The massive Smith Cloud of hydrogen gas is on a collision course with the Milky Way galaxy, and while most gas clouds are destroyed in our galaxy's outer layer of hot ionized gas, scientists have discovered the cloud has a special line of defense: a "magnetic forcefield."
It's a galaxy far, far away. Astronomers scanning the heavens discovered the most distant known galaxy lying so far away that it gives scientists a look at the universe's infancy.
Scientists NASA's Chandra X-Ray Observatory have discovered the largest number of black holes in a galaxy outside of our own, and they're all right next door, ready to collide with our galaxy in several billion years.
A team of University of California Irvine (UCI) scientists has uncovered the cosmic equivalent of an elephant smaller than a mouse: a dwarf galaxy so small it only contains around 1,000 stars.
Scientists scanning the heavens have come across a rather unique and rare phenomenon - a galaxy that essentially has the maximum efficiency rate in star creation.
Awe-inspiring and eye-pleasing as they may be, the arms of spiral galaxies have remained a luminescent mystery to scientists for quite some time. New detailed computer simulations, however, are revealing more about spiral galaxies' arms, including the fact that they aren't as transient as previously thought, and that once formed, they sustain themselves.
The Hubble Space Telescope has spotted some of the earliest galaxies ever seen by man.
An blast from a quasar is the most powerful ever recorded, and could help scientists better understand the link between quasars and large galaxies.
NASA astronomers have announced that they have found the most distant galaxy using the Hubble and Spitzer space telescopes.
Scientists have found the first definitive hot gas bridge, spanning 10 million light-years, between two galaxy clusters.
Scientists have identified a galaxy so far away that the light we see from it began its journey to us only 400 million years after our universe was created.
Galaxies, much like humans, embrace chaos in their youth, and stabilize over time as they grow, according to astronomers.
Researchers have released a 3D map of over 500,000 galaxies and 100,000 quasars that helps them peer back in time to understand universe expansion and dark matter and dark energy.
