The most dense galaxies known to exist in our universe have been discovered by 2 undergraduate students while looking through years of archival data.
Astronomers convened to present the latest findings on just about everything under the sun, and well beyond our solar system.
Powerful jets of material spewing from the edge of monster black holes may be more likely to arise where two galaxies have merged together.
Astronomers studying the globular star clusters orbiting the giant elliptical galaxy Centaurus A (NGC 5128) have stumbled upon a fascinating discovery -- the clusters are too massive.
Astronomers have found a quartet of quasars embedded in a single cloud of cold gas, a discovery that challenges currently held theories about how these rare objects form.
The Andromeda galaxy, the nearest spiral galaxy to our Milky Way, is sporting a massive halo of hot gas spanning a million light-years into intergalactic space.
A galaxy far, far away — farther, in fact, than any other known galaxy — has been measured by astronomers.
Astronomers have taken a census of distant spiral galaxies to help us understand what our Milky Way may have looked like in the distant past, also providing us with an invaluable look at the evolution of our own solar system.
