Scientists have discovered that "comatose" galaxies can be resurrected. If clusters of galaxies merge, a cosmic tsunami can drive the birth of a new generation of stars.
Astronomers have spotted 11 runaway galaxies that have been flung from their original homes to wander through space.
Giant galaxies may actually die from the inside out. Astronomers have shown for the first time how star formation in "dead" galaxies sputtered out billions of years ago.
Earth's sun apparently came late to the Milky Way galaxy.
Astronomers may have discovered baby galaxy clusters in our distant universe that could reveal a bit more about galaxy evolution and the role played by dark matter in shaping these clusters.
The Karl G. Jansky Very Large Array (VLA) has captured a spectacular, detailed image of one of the most fascinating regions of the universe. It's taken a picture of an area where clusters of hundreds of galaxies are colliding with one another.
While some galaxies are veritable star nurseries, others went barren years ago. Yet what causes some galaxies to produce new stars while others go silent? That's a good question and now, astronomers may have found the answer.
Astronomers have made a somewhat unusual finding. They've found a galaxy that looks old, but exists in a young universe. The findings reveal a bit more about galaxy formation and tell them a bit more about the early universe.
Why do starburst galaxies "burst?" Now, scientists may have found out why by dissecting a cluster of star-forming clouds at the heart of NGC 253, a starburst galaxy close to the Milky Way.
Scientists have uncovered a startling new discovery in the heart of what they thought was a "boring" galaxy. They've discovered a supermassive black hole explosively heating and blasting the gas in the galaxy, creating a type of galactic storm.
Say "cheese!" The NASA Hubble Space Telescope has captured an image of the galaxy cluster SDS J1038+4849 that makes it look as if the galaxy itself is smiling. But the new image isn't just a pretty face; it also tells astronomers a bit more about this galaxy.
