Supermassive Black Hole Creates A New Kind of Star

Although a black hole is known for swallowing everything, it appears that this one is “giving birth” to a new star in the solar system, so miracles do happen. This supermassive black hole called Sagittarius A is located in the Milky Way center and basically keeps the galaxy together.

Using data from NASA’s Chandra X-ray Observatory and other telescopes, researchers discovered a black hole that had a very unusual behavior, so they decided to be more cautious and to observe it more often. They immediately found that the black hole had a great “appetite.”

Andrea Ghez (UCLA professor of physics and astronomy and a co-senior author of the research) said: “We have never seen anything like this in the 24 years we have studied the supermassive black hole. Black holes may be driving binary stars to merge. It’s possible that many of the stars we’ve been watching and not understanding may be the end product of [these] mergers.”

The Sagittarius A Supermassive Black Hole Creates A New Kind of Star

The first two G objects were discovered in 2005 and 2012. Because the two objects followed the orbit around Sgr A*, some astronomers interpreted them as some kind of gas ripped away from a dead star.

Andrea’s research group has discovered four new G objects that look quite similar. One of the things that have gotten everyone excited about the G objects is that the stuff that gets pulled off of them by tidal forces as they sweep by the central black hole must inevitably fall into the black hole.

Usually, these objects have a solid structure, but they disintegrate near a black hole during their orbits. Finding these objects was the simple part. Now, they have to start analyzing them and also searching for others. The fact that these objects have been found near the Sagittarius A supermassive black hole means they could actually be feeding the black hole. So, this could be a reason why this one created a new star.
