Gamma-ray beams seen in the Milky Way's central black hole suggest that the galaxy's center was much more active in the past, according to new research.

More than one billion stars in the Milky Way can be seen together in detail for the first time in an image captured by astronomers.

Astronomers from the U.K., France and Germany have discovered vast amounts of gas and dust in the galaxy containing the most distant supermassive black hole known to science.

A team of volunteers has pored over observations from NASA's Spitzer Space Telescope and discovered more than 5,000 "bubbles" in the disk of our Milky Way galaxy. Young, hot stars blow these bubbles into surrounding gas and dust, indicating areas of brand new star formation.
