Though tiny, this newfound satellite galaxy around M31 offers big lessons — and questions — about how galaxies evolve.

Today, astronomers have measured the distance to the Andromeda Galaxy much more precisely; they find it to be about 2 1/2 million light years away. It is a majestic spiral-shaped galaxy ...

Sgr A*, in turn, is dwarfed by some supermassive black holes detected in other large galaxies such as one with a mass 6.5 billion times greater than that of the sun in a galaxy called Messier 87. That ...

Uranus will be visible to keen stargazers with a telescope ... Galaxies are huge collections of gas, dust, and billions of stars. Our closest major galaxy is the Andromeda Galaxy. At 2.5 million light ...
