Green Bean Galaxy, also known as J0113+0106 and J1155-0147, are two galaxies that are a rare quasar ionization echos. Ionization Echos or Light Echo are physical phenomenon that are caused by a light reflection off a distant surface from some sort of source that is delayed relative to the distance of said object. GBGs or Green Bean Galaxies are extremely rare, so rare, that in fact, on-average, only one is seen every 1.3 Billion Light Years across in a cube. They are known as Green Bean Galaxies because of their observable green color. Green Bean Galaxies was discovered by German Astronomer Mischa Schirmer.
