Astronomers solve puzzle about bizarre object at center of our galaxy: Enormous black hole drove two binary stars to merge

     Astronomers saw a bizarre object in the center of the milky way and believed that it was a hydrogen gas cloud headed to our galaxy's huge black hole. The astronomers eventually realized that a hydrogen gas cloud would be torn apart by the black hole and would not still be there, so what could this object in the center of our milky way be?

     A team led by Andrea Ghez determined that the object that they had named G2 was most likely to be a pair of binary stars that merged together because of the black hole's powerful gravity. G2 continued its orbit around the black hole, controlled by the black hole's gravitational pull, and a hydrogen cloud would not have done this.

     Ghez and her colleagues went to Hawaii's W.M. Keck Observatory, which has the world's two largest optical telescopes. With these two telescopes they discovered that when two stars near the black hole merge together, it usually takes more than 1 MILLION YEARS before it settles down. They realized that some of the weird stars they have seen near the black hole before might be the end product of mergers that are much calmer now.

      G2 is now in a "spaghetti fication." This is a common phenomenon near black holes in which objects become longer. At the same time, the gas at G2's surface is being heated by stars around it, which makes an enormous cloud of gas and dust that covers most of the huge star.

      The researchers would not have figured this out without the two telescopes. The telescopes more clearly reveals the space around the enormously big black hole. This helped them understand what the massive star actually was.

       As you can see, the mysterious object in the sky is a pair of binary stars that have merged together. The black hole controlled its orbit with its powerful gravity. Ghez and the other astronomers would not have been able to figure the mystery out without the powerful telescopes, and they are starting to understand the physics of black holes in a way that has never been possible before.

Questions:

1. If you got to name the two binary stars that merged together, what would you name it, and why?

 2. If the two powerful telescopes were not made yet, how would it have effected the work of the astronomers?
