An unusual black hole has been discovered
near the constellation Gemini. It is 69 times more massive than the Sun, and its existence in our galaxy is hard to explain.

According to Professor Jifeng Liu from the National Astronomy Observatory of China, scientists have always believed that the Milky Way’s largest stars lose some of their mass at the end of their lives. Therefore, they are generally unable to produce that large of an object. The black hole discovered is twice as massive as what researchers thought was possible in our galaxy.
It all started with the LB-1 star, a young blue giant located about 15,000 light-years away from our planet. Researchers analyzed its spectral oscillations and found that the star orbits an invisible object every 80 days, and that object turned out to be a huge black hole.
Chinese astrophysicists and their colleagues hope that further studies of the phenomenon and similar discoveries will help us understand exactly how these ‘heavyweights’ have appeared, where they form, and why they barely absorb any matter and do not emit beams of X-rays, when they are near a large star.
