Around 2015, astronomers took on the painstaking task of stitching together Hubble Space Telescope images of this galaxy, but that effort had focused on the galaxy's northern half. Still, however, the ...

"We can tell it's got this big central bulge of older stars and a star-forming disk that's not as active as you might expect given the galaxy's mass." Astronomers refer to the Andromeda Galaxy as M31 ...

The Andromeda Galaxy, also known as Messier 31 or M31 ... Hubble can only detect stars that are brighter than our Sun, and many low-mass stars fall below its sensitivity threshold.

While the events observed around Sgr A* are dramatic, this black hole is not as active as some at the center of other ...

Einstein predicted that massive objects bend light as it passes through their gravitational field. This week, a new telescope ...
