cientists around the world are tracking a doomed cloud of gas as it makes a daring approach toward the monster black hole at the center of our Milky Way galaxy, a cosmic encounter that might reveal new secrets on how such supermassive black holes evolve.
The G2 space cloud, and its ultimate death by black hole, have been under close scrutiny since the cloud's fate was first identified in 2011. Now, the cloud is destined to be shredded by a supermassive black hole.
Although more than 1,000 exoplanets have been discovered since the first one was found in 1995, only a handful of those are thought to be habitable, at least by life as we know it. New research shows that exomoons, too, could provide habitable environments. Although we are yet to find exomoons, we have good reasons to believe that there should be many, even more than exoplanets.
