Introduction
Canis Major Overdensity also known as Canis Major Dwarf Galaxy, is a galaxy located within The Canis Major (Big Dog) Constellation. Canis Major Overdensity is a irregular galaxy 25,000 Light Years from The Solar System. Canis Major Overdensity was discovered in 2003 by A Team of Astronomers analyzing data from The Two-Micron All Sky Survey (2MASS). 
Stars in Canis Major Galaxy
Canis Major Overdensity has around 1 Billion Stars. Some of these stars include NGC 1851, NGC 1904, NGC 2298 and NGC 2808.
Ripped Apart
Canis Major Overdensity is being pulled apart by the gravitational force pull of our own galaxy, The Milky Way Galaxy. This causes a tidal disruption forming a ring that can wrap around The Milky Way Galaxy threefold called The Monoceros Ring. One day, thanks to our galaxy, Canis Major Overdensity may no longer exist. 

Introduction
Today, Man rules The World. Mankind Dominates every other species by far in terms of Power, Prestige, control and intelligence. The homosapien is The Top in Today's World. This was not always the case however. For, millions of years ago, The World was ruled by a different set of species. The World was ruled by Dinosaurs. 
Dinosaurs
Eons ago, Dinosaurs dominated the Earth. The eras of the dinosaurs were The Jurassic Era, The Triassic Era, and Cretaceous. A list of some of The Dinosaurs are:
- Tyrannosaurus Rex (T Rex), The King of The Dinosaurs
- Triceratops
- Diplodocus
- Velociraptor
- Spinosaurus
- Stegosaurus
- Brachiosaurus
- Ankylosaurus
- Megalosaurus 
- Mamenchisaurus
The Asteroid
The Dinosaurs were The Kings of The World for millions of years. None could stop them, except, a Big Rock. 66 Million Years ago, an Asteroid hit Earth and the impact made the Dinosaurs go extinct in a mass extinction event. If ye was not killed by the impact, the smug in the atmosphere would have. No Dinosaur was sparred from it's awesome impact on Earth. Today, we are believed to have discovered the crater where the asteroid, known as The Chicxulub impactor, striked Earth. Off The Yucatan Peninsula in Mexico North of Belize. The Chicxulub Crater is the official name of the impact zone and measures at 150 kilometers or 93 miles in diameters and has a depth of 20 kilometers or 12 miles! That's colossal! It is believe that the The Chicxulub impactor was believe to be 11 to 81 kilometers or 6.8 to 50.3 Miles in diameter! No wonder there was a mass extinction!
Conclusion
What the Mass Extinction of The Dinosaurs teaches us, is that we are not invincible and it only takes one big attack to destroy of all. We must remain vigilant, not paranoid, and expect the unexpected, the black swan. We must keep innovating a find a way to deal with a Chicxulub Impactor-like Asteroid in The future, less we go extinct ourselves in one veil swoop. If ye are not growing, ye are dying, and if we continue to adapt and improve, we can live on as a species, longer than The Dinosaurs. 

Introduction
Virgo Stellar Stream, a strange name for a galaxy compared to The Draco Galaxy, Andromeda Galaxy and The  Milky Way Galaxy; for it doesn't have the word galaxy in it's name. Nonetheless, Virgo Stellar Stream is still a galaxy. Also known as Virgo Overdensity, Virgo Stellar Stream is a dwarf spheroidal galaxy who, like The Andromeda Galaxy, will merge with our galaxy, The Milky Way; and in fact is in the process of merging with The Milky Way Galaxy. Located inside The Virgo Constellation, Virgo Stellar Stream was discovered in 2005 with suggestions of it's existence coming as early as 2001.
Virgo Bio
The Virgo Stellar Stream has a radius of 30 Kilo Light Years and is 30,000 Light Years from our Home World, Earth. The Virgo Stellar Stream was discovered by The Sloan Digital Sky Survey from Photometric data. The Virgo Stellar Stream gets int's name from The Fact that it is inside the Virgo Constellation and that it is a stream of stars. The Virgo Stellar Stream has a few hundred thousand stars within its boundaries. The reason for the low amount of stars, compared to other galaxies, is because a lot of the stars are star clusters. 

Introduction
The Milky Way Galaxy, The Galaxy that we call home. Once thought to be what encompassed the entire Universe, is now known as one of many like it. The Milky Way Galaxy is in fact one of about 100 Billion Galaxies! So much for The Milky Way being The Universe. Some of these other galaxies include, The Andromeda Galaxy, Sombrero Galaxy, Baby Boom Galaxy, Star Fish Galaxy & Virgo Stellar Stream. The Milky Way Galaxy has over 250 Billion plus or minus 150 Billion Stars in it's perimeters. It's radius is 52,850 Light years and The distance of The Sun to it's, likely Black Hole, Center is 26.4 plus minus 1.0 kly. And it takes about 240 Mega Light Years for  The Sun to revolve around the center of The Milky Way Galaxy. Yes, even The Sun revolves around something. 
Milky Way
The Name Milky Way, comes from the way we see the galaxy from Earth. Since we are inside of the actual galaxy, our view of its shape is quite obscured. Though we know now that The Milky Way Galaxy is a barred spiral galaxy, which means it is a spiral galaxy except that in the center is a bar shape of light. In Latin it is translated to via lactea and in Greek it is galaxias kyklos which translates from Greek to Milky Circle. 

Introduction
The Andromeda Galaxy, our neighbor galaxy, will one day; be a part of us. The Andromeda Galaxy has over 1 trillion starsand is a spiral galaxy! Andromeda Galaxy has a radius of 110,000 Light Years, which means, if ye went light speed through the Andromeda Galaxy, it would take ye 110,000 Earth Years from Start to End. It takes 2.537 Million Light Years to get from Earth to The Andromeda Galaxy. Discovered in 964 in Persia, Astronomer Abd al-Rahman al-Sufi describe it as a Nebulous Smear; which is why is was once known as The Andromeda Nebula. Other names for The Andromeda Galaxy are Messier 31, M31 & NGC 224. Not only is The Andromeda Galaxy our neighbor galaxy, it is also the nearest galaxy to our own. 
List of Stars
Some of the trillions of The Stars in The Andromeda Galaxy are Go And, AN And, HD 3883, 26 And, HD 225218, OP And, CG And, ET And, 51 And, 65 And, 2 And, 22 And, V428 And, 4 And, 10 And, LN And, GRB 34, Z And, WASP-1, S And, HAT-P-53 & R And. 
Andromeda Characteristics
The appearance of The Andromeda Galaxy as of visible light is classified as an SA(s)b Galaxy in the de Vaucouleurs-Sandage Extended Classification System which is a system that divides galaxies into the categories of Ellipticals, Lenticulars, Spirals & Irregulars. In the 2MASS survey data, Two Micron All-Sky Survey, which is an astronomy survey of The Whole Space Sky within the infrared view, it is a barred spiral Galaxy. 
Andromilky or Milkymeda?
One day in the future, The Milky Way and The Andromeda Galaxy will cease to be sovereign over themselves, one day, they shalt be one. Approximately 4 Billion Years from Today, Andromeda will collide with The Milky Way Galaxy and we will be a dual galaxy. Whether this will results in a peaceful fusion or a Super Awesome Powerful explosion, or a mix is yet to be known. Will this new galaxy be called Andromilky or Milkymeda? That's an answr only our predecessors 4 Billion Years from now can answer.
