ESO's Very Large Telescope (VLT) has given scientists their best ever look at a spectacular cosmic collision. Researchers now have a view of the motion of gas being ripped out of a galaxy as it smashes into a vast galaxy cluster at high speed.
When Comet Siding Spring brushed past Mars, scientists captured data using NASA's MAVEN mission. Now, researchers have found that the comet was actually the cause of an intense meteor shower and added a new layer of ions, or charged particles to the ionosphere.
Using the Hubble Space Telescope, astronomers have uncovered a startling diversity in debris systems that coincide with the formation of exoplanets.
Astronomers are peering back in time with the help of the Large Millimeter Telescope (LMT) and its Redshift Search Receiver. Using these instruments, they've managed to estimate the rate of star formation inside murky distant galaxies shrouded in dust clouds
Using an experiment carried into space on a NASA suborbital rocket, astronomers have discovered a diffuse cosmic glow that appears to be more light than what's normally produced by known galaxies.
The Hubble Space Telescope has captured a striking new image of the multiple star system, XZ Tauri, its neighbor and nearby stellar objects. The new picture reveals XZ Tauri blowing a hot bubble of gas into the surrounding space.
Astronomers have officially captured the best image to date of planet formation around an infant star.
Scientists have made the most accurate study so far of a cocoon of gas and dust surrounding a triple star system. Using complementary observations from multiple instruments, the researchers have identified the complex dynamics at work within the system, called GG Tau.
Scientists may have found out how Vesta became shaped like it is. Using computer models to simulate collisions on Vesta, scientists have found out how Vesta may have gotten the deep grooves that encircle its midsection.
Astronomers may have found out exactly what a certain thin, bizarre object at the center of our galaxy might be. They've discovered that this object isn't a hydrogen gas cloud, but may instead be a pair of binary stars that is orbiting the black hole at the center of the Milky Way galaxy.
The Royal Observatory Greenwich and BBC's Sky at Night magazine hold a contest each year for the most amazing astronomy photos.
