Astronomers may have just caught the first glimpse of the earliest stages of galaxy construction. They've spotted a building site, nicknamed "Sparky," that is a developing galaxy containing a dense core blazing with the light of millions of newborn stars.
Scientists may have just taken one step closer to uncovering the origin of the ultraviolet light that bathes our universe. The findings could tell researchers a bit more about how galaxies were first formed.
The NASA Hubble Space Telescope has captured the best view yet of two colliding galaxies that merged when the universe was only half of its current age. The latest image reveals a bit more about how these events occur in our universe.
Astronomers have managed to view the "Whirlpool Galaxy," Messier 51, with the Low Frequency Array (LOFAR) radio telescope in a frequency range just above those of commercial FM radio stations.
Astronomers have spotted a stream of gas that's a staggering 2.6 million light years long with the help of the William E. Gordon Telescope.
Astronomers have discovered one of the most distant galaxies to date. Not only that but the galaxy, which breaks the previous record holder by 200 million years, also serves as a cosmic magnifying glass, revealing new clues about the early universe.
Satellite galaxies move in rotating discs around larger ones. Yet these galaxies aren't predicted by current models, leaving astronomers baffled.
Astronomers are learning more about our universe each day. Now, they've taken a closer look at dwarf galaxies and have found that they don't "swarm" around larger ones like bees, but actually "dance" in orderly, disc-shaped orbits.
Astronomers have uncovered seven new dwarf galaxies while probing a nearby spiral galaxy. Using a new type of telescope, the researchers' finds may yield important insights into dark matter and galaxy evolution.
The NASA Hubble Space Telescope has made an unusual discovery. It's taken a snapshot of two elliptical galaxies merging into one while a "chain" of young, stellar superclusters wind around the galaxies' nuclei.
In this case, a certain galaxy is both red and dead. Astronomers have discovered the carbon monoxide in a galaxy located about 12 billion light-years from Earth and have found that it's running out of gas, slowly pushing it toward its own destruction.
Astronomers have discovered that the supermassive black holes at the cores of some galaxies drive massive outflows of molecular hydrogen gas, which can directly impact the galaxies' evolution.
