Milky Way’s Black Hole Grew 75 Times Brighter for a Few Hours

Even though the black hole at the center of the Milky Way is a monster, it’s still rather quiet. Called Sagittarius A*, it’s about 4.6 million times more massive than our Sun. Usually, it’s a brooding behemoth. But scientists observing Sgr. A* with the Keck Telescope just watched as its brightness bloomed to over 75 times normal for ...

Milky Way Heading for Catastrophic Collision

New research led by astrophysicists at Durham University, UK, predicts that the Large Magellanic Cloud (LMC) could hit the Milky Way in 2 billion years’ time. The collision could occur much earlier than the predicted impact between the Milky Way and another neighboring galaxy, Andromeda, which scientists say will hit our galaxy in 8 billion years. ...

Doomed Star in Milky Way Threatens Rare Gamma-Ray Burst

University of Sydney astronomers, working with international colleagues, have found a star system like none seen before in our galaxy. Scientists believe that one of the stars — about 8,000 light-years from Earth — is the first known candidate in the Milky Way to produce a dangerous gamma-ray burst, among the most energetic events in ...

Confirmed Collision Between 2 Milky Way Satellite Galaxies

If you’re standing in the Southern Hemisphere on a clear night, you can see two luminous clouds offset from the Milky Way. These clouds of stars are satellite galaxies of the Milky Way, called the Small Magellanic Cloud and the Large Magellanic Cloud, or SMC and LMC. Using newly released data from a new, powerful ...
