Astronomers have identified what the strange object at the center of the Milky Way galaxy is. They previously believed Milky Way’s mysterious object was a hydrogen gas cloud. It turns out that’s not what it is. Supposedly the mysterious appearance could be a pair of binary stars which orbits the black hole in the center of our galaxy.
Milky Way’s mysterious object is called G2 and in the past scientists believed it was a hydrogen cloud. But if it had been one the black hole at the center of Milky Way would have torn it apart. The results would have been celestial fireworks which would have changed the state of the galaxy’s black hole.
Andre Chez, one of the scientists who studied Milky Way’s mysterious object said that:
“G2 survived and continued happily on its orbit; a simple gas cloud would not have done that. G2 was basically unaffected by the black hole. There were no fireworks.”
The astronomers believe that G2 is one of the emerging class of stars close to the black hole which are created by the powerful gravity coming from the black hole. This gravity forces the binary stars to become one. The stars in our galaxy usually come in pairs. Scientists believe that the mysterious object in the Milky Way is actually a star which suffered an abrasion to its outside layer. When two stars become one near a black hole, the new star can expand for up to one million years before settling back down. Astronomers believe that this is the case with the GS star, and that the star is in the inflated stage at the moment.
Andre Chez said that,
“This may be happening more than we thought. The stars at the center of the galaxy are massive and mostly binaries. It’s possible that many of the stars we’ve been watching and not understanding may be the end product of mergers that are calm now.”
Right now Milky Way’s mysterious object, G2, is elongating near the black hole. Also, the surface of the G2 is heated by all the stars around it, which creates a giant cloud of gas, covering most of the big star’s surface.
