Achernar is most noted for being an oval shaped like a chicken egg. Achernar is within our Galaxy, The Milky Way Galaxy and is in fact, the least spherical star observed within The Milky Way Galaxy. Introduction
Vega, also known as Wega, Lucida Lyrae, Alpha Lyrae, α Lyrae, 3 Lyrae, BD+38°3238, GCTP 4293.00, HD 172167, GJ 721, HIP 91262, HR 7001, LTT 15486 and SAO 67174, is a Blue-tinged White Main Sequence Star (A0V) located in the Lyra Constellation. Vega has a mass of 2.135 Solar Masses, a Solar Radius of 2.362 Solar Radiuses, and a Luminosity of 40.12 Solar Luminosities. Vega has a temperature of 9602 Kelvin and a Surface Gravity of 4.1 Centimetre-gram-second system of units. Vega is 455 Million Years Old. Vega is 25 Light Years from The Sun. Profile of Vega Vega is the fifth-brightest star in the night sky here on Earth. It is also the brightest star in the northern constellation of Lyra. It has been studied so much that it is in fact nicknamed "arguably the next most important star in the sky after the sun."[Sic] Around 12,000 B.C., when humans were thought to have walked to places on Earth such as Australia and New Guinea, was when Vega was the Northern Pole Star. Today that star is Polaris. Thought Vega is old, The Sun is tenfold the age of Vega making it relatively young. Nova
A Nova is an Astronomical phenomenon that begets a spontaneous appearance of a bright apparently new star that will fade in brightness over the period of many weeks or months. The different causes of a nova are as divergent as they come. One Thing is in common however; All Novae or Novas, involve a white dwarf within a near proximity binary system. The Main Classes of Novas are The Classical Novae, Recurrent Novae (RNe) and The Dwarf Novae. All three classes are considered cataclysmic variable stars. The Classical Nova The Classical Novas are the most common form of Nova. The Creation of Classical Novas are probably a close binary system encompassing a white dwarf and either A Main Sequence Star, A Giant Star or a Red Giant Star. The Orbital period of The White Dwarf and it's companion star is around one day to several days long. Over the days of these orbits, the accreted matter of the companion star will be pulled to the surface of The White Dwarf which in turn, creates a dense and shallow atmosphere made mostly of hydrogen. This hydrogen is then heated by the white dwarf and the high temperature rise high enough to ignite causing speedy runaway fusion. The Spontaneous increase in Power and Energy expels the atmosphere into Interstellar Space which then creates an envelope seen by the observer as visible light. This is why a nova can be mistaken for a new star being born. Recurrent Novae Recurrent Novas are novae that continuously bursts in intervals. These type of Novae are rare with only 10 known in Today's World (May 2020) The Intervals typically occurs in the magnitude of decades. Dwarf Novae Dwarf Novae, also known as a U Geminorum-Type Variable Star, is a novae that mocks the same quality of The Classical Novae, except is much dimmer, less Grand, and repeat more frequently than The Classical Novae. Introduction
Magnets, they stick together when a Positively Charged side and a Negatively Charged Side face each other. All who graduated Elementary School should know this basic fact. These magnets and even the ones on thy refrigerator are actually quite weak when compared with a Magnetar. A Magnetar a Neutron Star with a Super Extremely Powerful Magnetic Field. Neutron Magnet The Magnetar can have a magnetic field range of 100,000,000,000,000 gauss to 10,000,000,000,000,000 gauss or 10,000,000,000 Tesla to 1,000,000,000,000 Tesla. A gauss sometimes symbolized as G or Gs, is a cgs unit of measurement named after German Physicist Carl Friedrich Gauss. A Tesla, symbolized by T, is a unit of magnetic induction used in The International System of Units named after the Serbian-American inventor Nikola Tesla. A Magnetar's magnetic field will decay in Power of the emissions of X Rays and Gamma Rays overtime. Like Normal Neutron Stars, Magnetars are also usually 20 Kilometers or 12 Miles in diameter and are twofold as massive as The Sun in our Solar System. The Powerful First Discovery The First Magnetar was discovered in March of 1979. At this time on the fifth of March, two Soviet Union space probes (unmanned) were struck by an Awesome Blast made of Gamma Radiation. The reading of radiation on the two probes, Venera 11 and Venera 12, in the timespan of a millisecond, went from 100 counts per second to 200,000 counts per second! An almost Instant change. Eleven seconds later, The Awesome Blast of Gamma Rays Attacked The Nasa Space Probe, Helios 2. The Blast was 100 fold that of a Solar burst from The Sun! This blast was discovered to being coming from Galaxy, Large Magellanic Cloud. The preparater, SGR 0525-66. The First Magnetar was discovered. This event would go on to be known as GRB790305b. Introduction
Pulsars, Pulses from Neutron Stars & Quasars, Pulses from Black Hole. Balzars or Blazors are Active galactic nucleus that with a jet comprised ionized matter, is directed at the observer on Earth. A Blazor comes from The Center of a Galaxy that contains a Supermassive Black Hole. The Ionized matter itself travels at near light speed toward the observer. Blazar/Blazor The First Blazar was discovered in the late 1950s via Radio Astronomy. The Blazor is a Powerful source of energy emission all across the electromagnetic spectrum. The Blazar comes in two categories, The BL Lac Objects & The Optically Violently Variation (OVV) quasars. In visible-wavelength images, almost all blazars are seen to be compact and like a dot, but high resolution images have revealed that Blazors are located at the centers of elliptical galaxies. Large one's with Supermassive Black Holes to be exact. The Blazor is powered by the matter fallout of The Supermassive Black Hole in The Center of The Elliptical Galaxy. Introduction
Super, is a word that describes Power, Big, Strong, Extra. The definition for Super in The Oxford Dictionary is Extremely Good. The word Massive describe that of something Big, Large, Giant, Colossal, etc. The Oxford definition of Massive is Extremely Large or Serious. A Black Hole according to The Oxford Dictionary is "an area in space that nothing, not even light, can escape from, because gravity (= the force that pulls objects in space towards each other) is so strong there". Now what do we get when we combine all of these words into something real? A Supermassive Black Hole. But, what is a Supermassive Black Hole and when does it happen? Supermassive Black Hole A Supermassive Black Hole is known as The most gigantic of the types of Black Holes. These Supermassive Black Holes are gigantic, and it is believed that they are in the center of a Large Galaxy including our own, The Milky Way Galaxy. Now just because it's bigger, doesn't mean it is more powerful. Supermassive Black Holes are believed to have less gravitational force than that of a common Black Hole. So it may be bigger, but it ain't better. Nay, for yes, it may hold an entire galaxy together, but a regular ole joe smoe Black Hole is indeed, stronger than a Supermassive Black Hole. A Supermassive Black Hole is formed when one Black Hole consumes enough of other Black Holes and matter, becoming larger and larger until it finally becomes large enough to be classified a Supermassive Black Hole. Conclusion The Supermassive Black Hole shows usv that just because something is bigger, doesn't mean it is stronger or better. There is a Biblical Story of both David and Goliath. Goliath is a colossal Giant, while David is mere young man. It like a Parrot versus a T Rex. That does not stop David however, from defeating Goliath. Sometimes, smaller things have a much greater force than larger things. Think of a bullet as opposed to a spear. While yes, the spear is larger, the bullet is much more deadly. It all depends on how it is used, and how it functions. Bigger is not always Better. Introduction
In Ancient China, a Solar Eclipse was thought to be a Sun Eating Dragon, so what was a Lunar Eclipse? A Sun Reviving Phoenix? Not likely. At least there is no written record of that being the belief. A Lunar Eclipse like A Solar Eclipse, has to do with The Sun, The Earth, The Moon & The Position of The Trio Lunar Eclipse A Solar Eclipse is when The Moon cover The Sun's Position completely, The Opposite would be deadly, however, a semi opposite does happen. It's called a Lunar Eclipse. A Lunar Eclipse is when The Moon gets no shine from The Sun because it is completely on the opposite side of The Earth from our vision. Only the light from The Earth, shows it's even there. Conclusion The Lunar Eclipse, Like The Black Hole and Dark Matter, shows us that just because ye cannot see something, that does not mean it isn't there. We know of and feel wind. Can we see wind? How about our Skeletons, we know we have them, but can we see them? There are things that cannot be seen but are known to be, emotions for example. And sometimes, it's the invisible things that are the most important. Introduction
Thousands of years ago in Ancient China, there was a Tradition of stopping a Dragon from devouring The Sun. One random day, The Sun would just be sitting there, minding it own business in the morning sky, and then all of a sudden, it would go dark. A Dragon was eating it! The peoples of Ancient China, did not take this lightly. They made noise! They screamed at The Dragon and caused a ruckus to scare The Dragon away. This always worked, but why did this work every single time? Solar Eclipse Was there really a Sun-Eating Dragon in the sky, and did The People of Ancient China really have any effect on the course of this event? No to both questions. The people had absolutely no control on the event and there was no a Sun-Eating Dragon; because instead of a Dragon, was, The Moon. This particular event, they confused for a Dragon eating The Sun, is what is known in Today's World, as a Solar Eclipse. A Solar Eclipse is when The Moon, Luna, moves completely in front of The Sun from our direct sky view. This causing The Sun's Shine to be covered causes a brief night time. A Solar Eclipse can last up to 7 minutes and 31 seconds long. Definitely not a long enough night to get the recommended eight hours of sleep a man needs. Not to worry, the real night time will come later. Solar Eclipses occur on around The World about every 18 months though in some part of The World, it only occurs once every 360 to 420 years. Conclusion So it's not a Dragon eating The Sun, it's just the Moon covering it's shine. Old ideas are not dumb ideas, but with limited knowledge, one can only think of so much. As we grow as a species, we continue to improve our broad range our collective knowledge. We may 'know' a lot of things today, that in the future, may be wrong. We must not let certain knowledge be absolute. For once we were screaming at Dragons, and now, we view the same event with awe. What is fact today, can be fantasy tomorrow. Always remember to continue to improve, and we will continue to know more and more about The World. Introduction
Quasars, also known as QSo or Quasi-Stellar Objects, is an Powerful luminous active galactic nucleus (AGN). The AGN occurs when, a gaseous accretion disk surrounds a Supermassive Black Hole that is millions to billions fold the size of The Sun. The gaseous accretion disk plummets into The Supermassive Black Hole producing tons of energy called electromagnetic radiation. The Super Power produced by a Quasar is colossal and The Top Powerful Quasars produce a luminosity multi thousandfold that of a Galaxy. Discovery Quasars were first discovered in The Late 1950's via The All-Sky Radio Surveys with the first two being 3C 48 & 3C 273. In 1960, Hundreds of Quasars were discovered that year alone. These discoveries were recorded in the Third Cambridge Catalogue. In 1963, The ID of 3C 48 as an olptical object was confirmed. IN The 1970's it was discovered that not all quasars were Super Powerful as initially researched in the earlier years. Subtypes of Quasars The taxonomic scheme of Quasars come in many varieties of different subtypes. Some of these are: - Broad Absorption-line Quasars or (BAL) Quasars are those quasars that display a broad amount of absorption lines that are blue shifted to that of it's own rest frame. This is a result of the gas flowing out of the active nucleus in the direction of the observer. - Optically Violent Variable or (OVV) Quasars are those that are radio-loud and have The Jet are pointed toward the observer. - Radio-Loud Quasars are quasars with Powerful Jets that are intense sources of radio-wavelength emission. - Radio-Quiet Quasars are quasars less powerful jets, with weaker radio emission than that of the radio-loud Quasars. - Red Quasars are quasars with optical colors that are redder than normal and this is thought to be because of moderate amounts of dust within the quasar host galaxy. - Type II Quasars are quasars where the accretion disk and broad emission lines are highly obscured by a dense amount of gas and dust - Weak Emission Line Quasars are quasars that have a hard to make out emission lines of that of the ultraviolet/optical spectrum. Name of Quasars A few of the names of confirmed Quasars are 3C 48, 3C 273, Einstein Cross, Twin Quasar, Triple Quasar, Cloverfield, Teacup Galaxy, Webster LQG & QQQ J1519+0627 Introduction
The Brightest Star in the night sky. The illumination is great indeed. Only The Sun can compete, but The Sun is in the morning sky. The Sun rules the day, Sirius rules the night. I am being serious. The brightest star is Sirius. Location Sirius is located in The Canis Major (Big Dog) Constellation. Sirius is within our own galaxy, The Milky Way Galaxy. Sirius is 8.6 Light Years away from Earth. Facts Sirius is also known as Alpha Canis Majoris or The Dog Star. Sirius is a Binary Star. It Companion Star is known as Sirius B and Sirius B is in fact a similar size to that of The Sun even though it is a White Dwarf. Sirius B is actually the first White Dwarf to ever be discovered. Sirius and Sirius B are around 20 Earth's distances apart. Sirius is a Blue-White Star that is 25.4 fold brighter than The Sun. Sirius has a surface temperature of 9940 Kelvin or 9667 degrees Celsius or 17,432 degrees Fahrenheit. Sirius has a diameter of 12,000 Kilometers. Introduction
With each Pulse, Aloha is given to thee though blood. Without the pulse, Aloha is not with thee. Thou art Haole without the pulse. With all blood within thy veins, thou art a unique individual whose purpose is unique within itself. Stars too can have Pulses. Neutron Star As was discussed in earlier times, A Neutron Star is a collapsed Supernova from a Red Giant or Blue Giant Star. Besides Black holes, Neutron Stars are both the smallest and densest stars in The Universe. They are even called White Stars. Neutron Stars that have a Pulse are called Pulsars. Pulsars A Pulsar is a Neutron Star that has a high magnetized rotation which emissions beams of electromagnetic radiation out of its magnetic poles. Pulsars form when a Neutron Star keeps the majority of its angular momentum then forms a very fast rotation speed. With this being, a beam pulsates from The Neutron Star in radioactive form and a pulse is seen. The Power of The Rotation in The Pulsar comes from its initial rotational energy in The Neutron Star. When The Pulsar's spin-period slow down a good amount, the radio pulsar mechanism is thought to turn off thus ending the Pulsar. This point is called The Death Line. A Pulsar will live from 10 Million years to 100 Million Years. As of this time, there have been approximately over 2000 Pulsars discovered in Space. A few names of these Pulsars are: Crab PSR, Hulse-Taylor Binary, PSR J0437-4715, Vela Pulsar, Geminga, Black Widow Pulsar, Bursting Pulsar, RX J1856.5-3754, AR Scorpii, Hercules X-1, 3C 58 & Calvera. Conclusion Even Stars can have pulses. A Black Hole can be seen a death; without the breathe; Haole. A Neutron Star; A White Hole; who has a Pulse can be seen as Aloha, The Breath of Life. Two counters that are a part of life. One can choose death or life. One can choose Haole or Aloha; it's up to be. Be a Black Hole of doom or a Pulsar of Aloha. Introduction
There is an array of all kinds of Star and Star things. This list includes Supernovae, Solar Stars, Red Giants, Blue Giants, Red Supergiants, Blue Supergiants, Neutron Stars, White Dwarfs, Black Dwarfs, Brown Dwarfs, Planetary Nursery, Planetary Nebula and Black Holes. There is still one type of Star we hath not discuss so far. That star is, The Red Dwarf. Small Red Star A Red Dwarf is the smallest and coolest star in The Main Sequence Star Stage. It's red, as we see by its name. It's spectral class is L0 to L2, giving it the red light. It has a small mass, approximately 7.5 percent of The Sun's mass. Type M red dwarfs have maximum temperature is 3900 Kelvin or 3626.85 degrees Celsius or 6560.33 degrees Fahrenheit. Type K red dwarfs have a maximum temperature of 5200 Kelvin or 4926.85 degrees Celsius or 8900.33 degrees Fahrenheit. Due to a red dwarfs small stature, it produces a small amount of fusion rates and pressure which leads to it having such a low temperature. This does help it live longer than other types of stars. For example, A Solar Star, like our Sun, lives around 10 Billion Years while a Red Dwarfs lives for 100 Billion Years. The life of Red Dwarf compared to The Solar Star is tenfold! Red Dwarfs last longer than the current age of The Universe, 13.8 Billion Years, Incredible! Red Dwarfs in The Universe. There are an estimated 80 Billion Red Dwarf Stars in The Universe. 20 Billion of those are Binary and the other 60 billion are single stars. A few of these stars are TRAPPIST-1, Proxima Centauri, Barnard's Star, Lacaille 8760, Gliese 581, Wolf 359, VB 10, Teegarden's Star, EBLM J0555-57, AD Leonis & Teide 1. Conclusion Red dwarfs show us that being small doesn't always put thee in a disadvantage. Sure, their size leads to lower temperatures, less awe, and less intrigue; but what is does have is longevity. Red Dwarfs outlive their other star counterparts by far. That's an advantage I bet we all would like to have. Introduction
Deep in Space is a darkness and despair so deep that even light and Joy cannot escape its grasp. The heavy weight of its force is more than anything in existence can deal with. You cannot see it for it is the king of darkness, the absence of light, the destroyer of all the bring vision to Aloha. All thou can see of it, is the dying light it steals from thy eyes sight. It is a Black Hole. Supernovae Start Supernovae of all types come from either Giant or SuperGiant Stars. A Supernova is a Super Powerful Awesome Space Star Explosion that is beautiful and awe inspiring. New Stars can be created by The Creator Supernova. A Supernova usually gives more than it takes, at least when it ends up becoming a Neutron Star. But what is it called when it takes more than it gives, essentially becoming materialistic and lacking a Transcendent Existential Purpose? Well, it's called a Black Hole. Black Hole When The Load on The Supernova is great enough, it will collapse in on itself. When this occurs all light and matter near it cannot escape its gravitational pull. Once you get caught, its over, you are trapped for eternity. There are a load of theorizes of what happens to the light and matter after it is captured varies and we do not know for sure. I will explore multiple theories in separate articles in the future. Conclusion A Supernova becoming a Neutron Star is like Virtue. It gives more than it takes and ends up beautiful even after death of its glory, its legacy is sealed. A Black Hole is like Vice, for it consumes all things around it endlessly and to no greater purpose. It captures and keeps all in its grasp for all eternity without relent. This goes to show the difference between Virtue and Vice and the real nature of Freedom. True Freedom is The Freedom to Pursue Virtue while The Freedom to commit Vice is not Freedom, for Vice imprisons the individual and the collective. Introduction
Nebulae name is rooted in Latin, it translates to Gas or Cloud. This would accurately describe a Nebula. A Nebula is in fact a Gas and Cloud in Space. So is a Star however, so what makes a Nebula different? Well to put it into more specific meaning, a Nebula is a gossamer cloud of gas and dust in interstellar space. It can have a range of some hundreds of light years. These Astronomical articles are not small by any means of the measure I do declare. On the conjury, Nebulae are beyond colossal in stature. I would dare to say, thou would not want to drive in this fog, thou would not be able to see the road clearly for thy entire life, even at light speed. The clouds on Earth have nothing on these odysseys. A few Nebulae we know of are The Eagle Nebula, Crab Nebula, Ring Nebula, Orion Nebula, Helix Nebula, Dumbbell Nebula, Horsehead Nebula, Omega Nebula, Lagoon Nebula, Eskimo Nebula, Veil Nebula, North America Nebula, Coalsack Nebula, Saturn Nebula, Pelican Nebula, Owl Nebula, Boomerang Nebula, Egg Nebula, Lemon Slice Nebula, Medusa Nebula, Ghost Nebula, Iris Nebula, Crescent Nebula & Flame Nebula. There are an estimated 3000 Nebulae in The Universe. The Origin of Nebulae Nebulae come from The Explosion of dying stars. These explosions come from Supernovae. Aftermath Nebulae after being created become a space for star creation. A Nebulae becomes Star Nurseries. Conclusion Nebulae come from the explosions of dying stars. Nebulae in turn become the birthplace of new stars. It's like a Hydra, thou cut off one head, two more grow in its place; except in a Nebula, more than two stars are born. This cycle is similar to life's cycle of life, death and rebirth. Except maybe the order is a little different. One lives, one gives new birth to another or others than one dies. Introduction
Black Dwarfs, don't exist, yet. At this time they are theoretical. This is because the it would take for a White Dwarf to cool down to become a Black Dwarf trillions of years. See the problem here? The Universe is only 13.8 Billion Years. There just hasn't been enough time alloted for this astronomical event to occur. So we're about 986 Billion Years off, for this to happen. IN all honesty, even more than that since this 986 Billion number comes from subtracting 13.8 billion out of 1 trillion. Earlier it was stated that it takes trillions of years for a White Dwarf to become a Black Dwarf. Plus this doesn't take into account the time it takes for a Star to become even a White Dwarfs. There are several steps taken before even that occurs. Protostar, Tauri Star, Main Sequence Star (Sun-Like Star size), then Red Giant, then Planetary Nebula and finally White Dwarf. That takes a long time. Even the Red Dwarf that skips straight into a White Dwarf still takes time to do. So we are nowhere close to observing a Black Dwarf, at least not in our Universe. A Black Dwarf Saying all this, the next question is begging to be asked. What exactly is a Black Dwarfs and what does it do? Not much is known due in being a theory, but the theory states that this stage in a Stars life is when a White Dwarf no longer pushes heat or luminosity, it will become invisible to the naked-eye. It will effectively be Black(the absence of light). It'll take special technology in order to even see it. This won't be impossible since recently a photo of a Black Hole, which light can't escape from its gravity, was taken. Conclusion It's crazy to think that something in the Astronomy core doesn't even exist yet. This should not surprise us however, for there was a point in time where we didn't even exist yet. Just because it doesn't exist now, doesn't mean it will in the future. This theory is a good one nonetheless. Why? Well, what happens when your in a room with no windows or openings and you turn the light off? Blackness. This would apply to something in space that doesn't emit or reflect light. Tell me, what is the color of space, not the object itself, but space? Exactly my point. It may be a theory now, but there is good reason to believe it will exist one day and someday, we may be able to observe it! Introduction
Many things happen to Stars after they die depending on their size. There are Supernovas, Black Holes, Planetary Nebulae, Neutron Stars, Black Dwarfs and White Dwarfs. White Dwarfs, also known as a degenerate star, is a dense ( density equal to that of H2O water times 1 Million) stellar core remnant that is near its end. White Dwarfs are mostly made of electron degenerate matter. Their mass is that near to The Sun. White Dwarfs want to become Neutron Stars, but simply do not have what it takes, the mass, to become a Neutron Star. White Star White Dwarfs are recognized for their White Color that they illuminate. It gets its color from the emissions of their stored energy. Fusion does not occur in a White Dwarf, i.e. part of why it is also called a Degenerate Star. No gravity necessary Most stars dead or alive, are supported against their own gravity via normal gas pressure; not White Dwarfs however. Instead White Dwarfs are supported by the degenerative pressure of their electron gas within their interior. Degeneracy pressure is an increased resistance exercised by electrons making up the gas, this is a result of stellar contraction. Composition of a White Dwarf White Dwarf's centers are made of a blend of both the elements Carbon and Oxygen. Around its center is a thin layer of helium; and a fine layer of hydrogen in most situations. Some White Dwarfs with actually have, though this is rare, have a thin carbon envelope. Where do White dwarfs come from? A Star that is initially 3 to 4 Solar Masses will become a White Dwarfs. This sometimes can be a higher number but typically the star is 3 to 4 Solar Masses. Stars that can become a White Dwarfs are Sun-Like Stars, Red Giants, Red Dwarfs & Planetary Nebulae. Our Sun will eventually become a White Dwarfs but first The Sun will expand and become a Red Giant. After this it will become a Planetary Nebulae. Over time, the mass of The Sun will wither away and The Planetary Nebula Sun will become a White Dwarf. Examples of White Dwarfs A few examples of White Dwarfs Stars are Sirius (The Brightest Star seen on Earth), Sirius A, IK Pegasi, Wolf 489, NN Serpentis, PSR J0348+0432, Procyon B & Lambda Boötis. There are currently believed to be 8 White Dwarfs in space. Introduction A Brown Dwarf, also known as a Failed Star, is a mass in space that is in between being labeled a Star or a Planet. This does not mean that a Brown Dwarf is small by any means of the measure, for a Brown Dwarf, while the size of 0.075% that of The Sun it is still as big as 75 Jupiter-sized planets. To be specifics a Brown can be from 2.5e+28 Kilograms to 1.5e+28 Kilograms. Examples of Brown Dwarfs are Upsilon Andromedae, Gliese 229, CT Chamaeleontis, Epsilon Indi & Xi Ursae Majoris B. Failure of a star What makes a Brown Dwarf a "failed star" is the fact that they do not retain a stable luminosity by thermonuclear fusion of hydrogen. Both Stars and Brown Dwarfs start off with their cores contracting and fusing hydrogen, achieving higher temperature. The difference comes later on when The Brown Dwarf ceases to contract due to their cores being dense enough to pause things with electron degeneracy pressure. For Brown Dwarfs the size above 60 Jupiters, will come to stabilize and fusion of hydrogen will halt. The Name Brown Dwarf Brown Dwarfs, despite their name, are not the color brown. Brown Dwarfs are actually a deep red or magenta color. Once Upon A Time, Brown Dwarf were titled Black Dwarfs, but it was later changed to Brown Dwarf, since it's actually color was reddish, but the title Red Dwarf was already taken, so Brown Dwarf became its new name. Afterlife of Brown Dwarf Brown Dwarf don't really die like other stars do, Brown Dwarfs simply remain Brown Dwarfs eventually cooling down more & more over time. Conclusion Some things in life never begin, sometimes they begin well and then never come into being. Either by chance or by lack of effort doth this occur. Brown Dwarfs being failed stars represents this well. If you do not get up and work at something, thou shalt suffer the same fate as a Brown Dwarf. Do not be stagnant in life, but move and improve thyself and thou can reach the stars! Introduction
Giant are among us in The Universe. The Giant Stars overpower in size that of The Sun bigtime. The Giant Stars themselves though, are not even the biggest, for they are too overpowered in size by Super Giants! Supergiants are as big as it gets, becoming so big that they either become Supernovae, Neutron Stars or Black Holes. There are two types of Supergiants, Red Supergiants and Blue Supergiants. Just like Giants are split into Blue and Red, so are Supergiants! Blue Super Giant Blue Supergiants are blue, of course, are extremely fierce in the sense of high temperatures and have a very high luminosity. In fact that are around 10,000 to One Million times brighter than The Sun. Blue Supergiants have a surface temperature of 10,000 Kelvin to 50,000 Kelvin or 9727 degrees Celsius to 49727 degrees Celsius or 17540 degrees Fahrenheit to 89540 degrees Fahrenheit. For a Main Sequence Star to become a Blue Supergiants it has to fit the following criteria: 10-300 Solar Mass ( A Solar Mass is equal to 1.989e+30 Kilograms, 4.385e+30 Pounds, 2.192e+27 Us Tons or 1.989e+27 Metric Tons) and be an O class or B class star (a B type star is a yellow star similar to The Sun, an O type Star is blue-white star with the spectral type O and are 10,000 to 1 Million times the size of The Sun.). These stars will evolve from their main sequence state and compose of heavier elements and expand continuously. Four examples of Blue Supergiants are UW Canis Major, Rigel, Zeta Puppis & MACS J1149 Lensed Star 1 also known as Icarus. Red Super Giant Larger than Blue Supergiants are Red Supergiants. Red Supergiants, by volume, are the biggest stars in The Universe. Their luminosity class is spectre type K or spectre type M. Despite their size, Red Giants are relatively cold compared to other stars, with a surface temperature falling below 4100 Kelvin (3827 degrees Celsius or 6920 degrees Fahrenheit). The Mass of Red Supergiants are 10 Solar Masses to 40 Solar Masses (1.989e+31 Kilograms to 7.956e+31 Kilograms, 4.385e+31 pounds to 1.754e+32 Pounds, 2.192e+28 US tons to 8.77e+28 US tons, 1.989e+28 Metric Tons to 7.956e+28 Metric Tons). Red Supergiants have a Solar Radius (R) of 264R to 303R (1.837e+8 Kilometers to 2.108e+8 Kilometers or 1.141e+8 Miles to 1.31e+8 Miles). One other characteristic of Red Supergiants are their slow rotational patterns. The minimum rotation velocity of a Red Supergiant is 5 km/s (Kilometers per second) This is still faster than a bullet, but compared to other stars, this velocity is relatively slow. Betelgeuse, a Red Supergiant, for example takes around 30 Earth Years to complete a entire rotation. Other examples of Red Supergiants are VY Canis Majoris, Mu Cephei & KW Sagittarii. Supernova Supergiants, Red & Blue become Supernovae when they die. One example of a Supernovae that was once a Blue Supergiant is Supernova 1987A who is a Type 2 Supernova. Conclusion What Supergiants and giants teach us is that, there is always someone bigger and better than the one who is bigger and better than thee. Even Giant Stars, themselves larger in their own respect, are dwarfed in comparison to Supergiants. However, being bigger isn't always an advantage. Red Supergiants for example are slower than other stars by a significant margin. This is true for all thing, living or nonliving. Introduction
The Sun is The Power of The Solar System! Without The Sun we on Earth wouldn't even be alive! The Energy from The Sun is what makes life on Earth possible. No Sun, no life. Now there are many stars in The Universe that come in a wide variety different from The Sun, but there are also stars like our sun. They are called Sun-Like Stars. Solar-type Star Sun-like Stars are also known as Solar analog or Solar-type Stars. Solar-Type Stars are a Main-Sequence star that have Yellow color. On the B-V Color Index it has a range of .48 and .80. The Sun is a .68 on the B-V Color Index. Examples of Solar-Type Stars are The Sun, Alpha Centaurus A, Delta Pavonis, Tau Ceti & 72 Herculis. Solar Analog Solar Analogs are like The Sun photometrically. This means that light and luminosity of The Sun and Solar Analog Stars are similar. Solar Analog Stars are a temperature of 5278 Kelvin to 6278 Kelvin or 5005 degrees Celsius to 6005 degrees Celsius or 9041 degrees Fahrenheit to 10839 degrees Fahrenheit. This is within 500 Kelvin (227 degrees Celsius or 440 degrees Fahrenheit) from the temperature of The Sun. Example of Solar Analog Stars are The Sun, Sigma Draconis, 51 Pegasi, 61 Virginis, 47 Ursae Majoris, 20 Leonis Minoris, Alpha Mensae and Psi Serpentis. Solar Twin A Solar Twin is a Star that is almost identical to The Sun hence the word twin. A Clone of The Sun hypothetically would be a G2V Star with a surface temperature of 5,778 Kelvin or 5505 degrees Celsius or 9941 degrees Fahrenheit. A Clone Star to The Sun would also have to be 4.603 Billion Years old (The Age of The Sun). To this date there hath not been a Clones of The Sun discovered. This does not mean it isn't out there in Space, but we have not observe one yet. Now a Star does not need to be a Clone of The Sun to be considered a Solar Twin, twins in the human species don't have the exact everything. To be considered a Solar Twin thou must be 50 Kelvin from The Sun (-223.15 degrees Celsius or -369.67 degrees Fahrenheit). The temperature range then is 5728 Kelvin to 6728 Kelvin (5455 to 6455 degrees Celsius or 9851 to 11651 degrees Fahrenheit). The Age of a Solar Twin is also 1 Billion years from the age of The Sun, older or younger. This means The Stars age must be between 3.6 giga-annum to 5.6 giga-annum. A giga-annum is a term used to describe a Billion Years, so 1 Billion equals 1 giga-annum; abbreviated Ga. Another term for a Solar Twin is a HabStar; Habitable Star. These stars, being so similar to The Sun, have the potential to house planets in its orbit that can support life like Earth does. To be considered a HabStar a star must be a Main Sequence Star, have the capability of maintain terrestrial planet in it orbit, have a age of at least 3 giga-annums, does not have a Stellar Companion Star, Support a stable habitable zone, and be not vary on its state of being. One Star that matches this criteria is HIP 11915 which is 185.53 Light Years from Earth. Examples of Solar Twins are The Sun, 18 Scorpii, Kepler-452, HD 150248 & HD 101364. Conclusion There is a lot of different astronomical objects in The Universe. There is even a multitude of different types of Stars. However, there are stars there are like our Sun. These Sun-Like Stars are all over the cosmos and they behave and look like The Sun, some may even have a planet orbiting it that contains life! We too, vary like the stars in the night sky and this might make us feel isolated and alone. Even if there are clones of us, like The Sun not having clones, this does not mean that we are alone in The World. There are hundred if not thousands or millions of people who have the same interest, look similar and act just like us. People with similar lifestyles and similar experience that we can find community and fellowship in. Finding these people is a key component of living a healthy life. When we find people who hold our same values, interest and experiences, we feel better about ourselves and key feature of human survival is found. Remember, no man is an island. Neutron StarIntroduction
Neutron Stars are star that are formed by the collapse of a Supernova Explosion from a Massive Star. Besides Black holes, Neutron Stars are the smallest and densest star in The Universe. Neutron Star have been called White Holes in fact; hypothetically, also they have been called quark stars and strange stars. A Neutron Star no longer generates its own heat and chills overtime. This does not mean that a Neutron Star is safe to walk on however, for an average Neutron Star is around 600,000 Kelvin or 599727 degrees Celsius or 1.1 Million degrees Fahrenheit. Definitely not safe to walk on, unless you want you feet to melt. A Neutron Star has a mass 1.5 times that of The Sun. However its radius is 10 Kilometers or 6.2 Miles. This means that runner running a Marathon will have ran around a Neutron Star a little over 4 times. This small size combined with the large mass means that the gravity on a Neutron Star is very high. A good analogy is a sugar cube thou put in thy cup of joe would weigh one hundred million tons on a Neutron Star. Now that's what I call some strong coffee. Supernova Start Every Star that is 8 times the Mass of The Sun has the possibility of becoming a Neutron Star one day in its lifecycle, or deathcycle technically. Before these Massive Star become Neutron Stars, they must go through one step. A Giant Star must first become a Supernova before it is to be a Neutron Star. More specifically it must become a Type 1B Supernova, Type 1C Supernova or a Type 2 Supernova. A Neutron Star forms from a highly swift rotational speed that overtime slows down to become a Neutron Star. There are times that Neutron Stars will have a glitch occur. A Glitch is a spontaneous and small increase in speed. This occurs due to a Starquake. Starquakes are just like Earthquakes, which rock the surface of the star causing the release of energy via seismic waves. There are also times where a Neutron Star will experience an Anti-Glitch which is a sudden decrease in the rotational speed. Aftermath Neutron Star that have a mass greater than 3 M will eventually collapse on its own weight and become Black Holes. This is the of the Neutron Star. Introduction
Star comes in a variety of different types. Not every Star is like The Sun, some are smaller and some are Giants. These Giants are legendary due to the unimaginable size they encompass. These Juggernaut Stars make our Sun look like a Rookie. There are even bigger Stars that are called Supergiants. Today though, we shall just discuss Giants. Red Giant Red Giants are gigantic, towering over and even over encompassing our own star, The Sun. These Stars are hot as hell! Red Giants have an average temperature of 5000 Kelvin, 4727 degrees Celsius or 8540 degrees Fahrenheit! Forget about getting a sunburn from this star, thou shalt receive a sun melt instead if not a sun vanish. This star however is in its late-stages of life. This star is about to die either becoming a Blue Giant than a Neutron Star, A Supernova than a Neutron Star, or a Planetary Nebula than a White dwarf. One day, our own Sun will become a Red Giant. This Star continues to expand, consuming anything in its path until one of the previously mentioned outcomes occur. This all happens because The Star's supply of Hydrogen atoms in the core have run out. This begins the imperial-like expansion of the star. This causes the star to become brighter due to its larger size than before. 3 famous Red Giants are Alpha Tauri, Alpha Bootis & Gamma Crucis. Blue Giant Blue Giants are rare as far as is known in Today's World. Blue Giants are Luminous and sizzling. Blue Giants however are not really a type of star as so much as a stage of a star. Blue Giants are evolved stars that have extensively lost its supply of hydrogen within its core. Eventually it will become a Red Giant and continues its path to death. An Example of a Blue Giant is The Blue Giant, Alcyone. Conclusion Whether a Blue Giant or Red Giant there are bigger stars out there in space than The Sun. We once thought that The Sun was the big boss in The Universe but that theory was squished overtime and now we know it isn't even close to being the biggest baddest star. This is a good lesson for us to understand for ourselves. That we should be humble and not believe we are the best in the world at a particular thing. The Old saying goes, that there is always someone bigger and tougher than thou art. This seems to be an universal truth that applies to more than just us humans. We should strive to be better versions of ourselves and not become static in our progress thinking that we are the best in the world; for eventually, voluntarily or involuntarily, we will be humbled and put in our place. Keep moving and getting better each and everyday and become the best version of yourself that thou can be. Do this, and thou shalt Thrive! |
