Our Long Lost Galaxy Sibling

In the recently conducted research, scientists have discovered that Andromeda which is the largest galaxy in the Local Group containing the Milky Way consists of a halo around it. The scientists have lately found out that the halo is the remains of a sibling galaxy of the Milky Way. It was assumed that the Halo was eaten up by Andromeda 2 billion years before. This spectacular discovery is called as M 32p. The name is exactly same as the newly launched model of mobile phone. But in reality it is not. On the contrary, M 32p is the long lost sibling of our Milky Way galaxy. It is indeed very surprising to know that an entire galaxy, which is a part of the Milky Way, was unknown till the present day. It’s been decades now ever since the scientists have been trying to unveil the mystery of the halo that was found near Andromeda. It was very difficult for the scientists to digest the fact that Andromeda, the largest galaxy in our Local group, consists of a halo which larger than its own size. After years of long research and hard work, the puzzle got solved. The scientists have deduced that halo is the remains of M 32, which was cannibalized by Andromeda around 2 billion years ago. Experts have used innovative ways to explain their discovery to the public at large. They put to use the analogy of a kid who has eaten his/her breakfast on a dining table while her mother was away from her. Here, the kid is the Andromeda, also referred to as M32. After a while, when the mother, in this case, the scientists, return back, she finds put that the little kid who she had left on the dining table is nowhere to be seen. The mother finds breadcrumbs all over the floor covering an area which is much larger than the size of the dining table. These breadcrumbs are indicative of the halo around Andromeda, which is a proof of the existence of M32.
