Milky Way, Supermassive Black Hole

Supermassive Black Hole Heading Towards The Milky Way Galaxy
The strange behavior of hypervelocity stars suggests a nearby dwarf galaxy must contain a supermassive black hole. If so, a collision with the Milky Way is inevitable.
There could be a supermassive black hole in the Large Magellanic Cloud hurling stars at the Milky Way
Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed. HVSs travel much faster than normal stars, and sometimes, they can exceed the galactic escape velocity.

Astrophysicists surprised by light show around the Milky Way’s supermassive black hole
Sagittarius A* is the supermassive black hole at the center of our home Milky Way galaxy. It has a mass equal to billions of suns and has an accretion disk made up of gas and dust surrounding it.
Webb telescope observes violence around Milky Way's central black hole
NASA's James Webb Space Telescope is providing the best look yet at the chaotic events unfolding around the supermassive black hole at the center of our Milky Way galaxy, observing a steady flickering of light punctuated by occasional bright flares as material is drawn inward by its enormous gravitational pull.
