According tomedia reports, the universe’s galaxies do not always look as beautiful and powerful as our milky galaxy, in the case of NGC 6240, an irregular galaxy about 300 million light-years from Earth, which looks like a broken egg.
Astronomers have long believed that collisions led to the creation of NGC 6240, which has two supermassive black holes inside, but the latest study is wrong: NGC 6240 actually has three supermassive black holes at the center of the galaxy.
The research paper, published last month in astronomy and Astrophysics, suggests that NGC 6240 may have been formed by a collision between three galaxies. The team observed the motion and mass of the black hole at the center of NGC 6240 using the Very Large Telescope (VLT) in Chile.
The centers of large galaxies usually have supermassive black holes, which are 100 million times larger than the mass of the sun. These black holes keep galaxies like the Milky Way moving constantly, spinning billions of stars and planets around the center of the galaxy, acting like a delightful cosmic carousel. But NGC 6240 is different.
It’s big, strangely shaped and very bright. Astronomers suspect that its intense light comes from a lot of dust. Previous studies have found two supermassive black holes in NGC 6240 that emit a ton of light — but now a new study from researchers at the University of G?ttingen in Germany and the University of Potsdam suggests that there may be another cosmic monster lurking in the galaxy.
Wlofram Kollatschny, an astronomer at the University of Gottingen and lead author of the study, said that through their observations and very high spatial resolution, they found that the interaction of the galaxy NGC 6240 hosted more than two, there are a third.
Peter Weilbacher of the Leibniz Institute of Astrophysics at the University of Potsdam and one of the co-authors of the study said it was the first sign that several galaxies and their central black holes were found to merge at the same time.
