Not long ago, the center of the Milky Way exploded

A titanic, expanding beam of energy sprang from close to the supermassive black hole in the center of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both poles of the galaxy and out into deep space.

Milky Way's Black Hole Has Grown 75 Times as Bright for a Few Hours

Observing Sagitarius A ( a supermassive balck hole in the center of our galaxy ) with the Keck's telescope, scientists just watched as its brightness bloomed to over 75 times normal for a few hours. Astronomers aren’t certain what caused the flaring. 

First detailed observations of material orbiting close to a black hole

The novel GRAVITY instrument has discovered clumps of gas swirling around at about 30 per cent of the speed of light on a circular orbit just outside the innermost stable orbit of a four million mass black hole.

Mystery objects whizzing about in Milky Way’s core

Spectroscopic measurements of gas dynamics at the core of the Milky Way have revealed several unusual objects visibly whizzing around the supermassive black hole at the center of the galaxy .

Stellar mass black holes swarm in Milky Way’s core

The Chandra Observatory has found direct evidence for up to 10 stellar-mass black holes and thousands more lurking within a few light years of Sagittarius A*, the supermassive black hole at the center of the Milky Way.

Tens of thousands of black holes may exist in Milky Way's center

Astrophysicists have discovered a dozen black holes gathered around Sagittarius A* (Sgr A*), the supermassive black hole in the center of the Milky Way Galaxy.

Infant stars discovered near Milky Way's supermassive black hole

ALMA has revealed signs of eleven low-mass stars forming perilously close — within three light-years — to the Milky Way’s supermassive black hole, known to astronomers as Sagittarius A*.

Astronomers just switched on a device that lets them observe the Milky Way's black hole

Astronomers working with the European Space Agency's (ESO) Very Large Telescope (VLT) in Chile have just announced that a black hole-observing device called GRAVITY is now fully operational and it's has already provided one accurate measurement.
