A second black hole at our galaxy’s center?
There’s a supermassive black hole – 4 million times our sun’s mass – in the center of our Milky Way galaxy. Astronomers who’ve measured star movements near this central black hole are now saying there might be a 2nd companion black hole near it.

A new way to measure cosmic black holes
Supermassive black holes are the largest black holes, with masses that can exceed a billion Suns. Just this spring, the first-ever image of the supermassive black hole at the center of the Messier 87 galaxy was taken, and researchers recently spotted the largest supermassive black hole ever seen. Despite these groundbreaking efforts, figuring out how these black holes drive a galaxy’s…
Thousands of exoplanets may orbit supermassive black holes
It sounds unbelievable, but a new study from Kagoshima University and the National Astronomical Observatory of Japan says that exoplanets – thousands of them – could be orbiting supermassive black holes. Source: https://earthsky.org/space/thousands-of-exoplanets-may-orbit-supermassive-black-holes…
Planets around a black hole? Calculations show possibility of bizarre worlds
Theoreticians in two fields defied the received wisdom that planets only orbit stars like the sun. They proposed the possibility of thousands of planets around a supermassive black hole. Source: https://phys.org/news/2019-11-planets-black-hole-possibility-bizarre.html…
Black hole hurls star out of Milky Way
Astronomers have spotted a star – S5-HVs1 – speeding out of the Milky Way at around 4 million miles (more than 6 million km) per hour. They believe it’s being ejected from our galaxy after venturing too near the giant black hole at the Milky Way’s heart about 5 million years ago.

Star Ejected from Milky Way’s ‘Heart of Darkness’ Reaches Mind-Blowing Speed
As humankind’s ancestors were learning to walk upright, a star was launched out of the supermassive black hole at the center of our galaxy at a staggering 3.7 million mph (6 million km/h). Source: https://www.livescience.com/star-ejected-milky-way.html
