Studying a galaxy from the inside may be tricky, but astronomers are still trying to learn a lot about our galaxy, according tomedia. Scientists believe one of their understandings about our galaxy — and many similar to ours — is that it orbits a black hole. In the Milky Way, for example, the central object of the Milky Way is thought to be a supermassive black hole. But new research from astrophysicists suggests that Sgr A, the center of our galaxy, may still have a black hole friend.
In a new study, a group of astrophysicists says they can better understand what is happening by observing the motion of stars near the center of a galaxy — even though they can’t actually see black holes directly.
While observing A particularly famous star, S0-2, the team noted that while there is no conclusive evidence that there is a small black hole around the main black hole, this possibility cannot be ruled out.
Next, observations of stars will no longer be the only tool in scientists’ arsenals, and in the future they will have an advanced detector called LISA (Laser Interferometer Space Antenna). It is currently under development and will likely lead to new discoveries for scientists, which could reveal that there is a second black hole at the center of our galaxy.
