The Hubble Space Telescope captured the image of two galaxies as they smashed into each other, forming a giant elliptical galaxy, NGC 3597.
Astronomers have captured the image of a supermassive and super-hungry spiral galaxy that is located 65 million light-years away.
An "X" marks an unusual spot on Pluto's plains
Astronomers used data from NASA's Great Observatories, which enabled them to carry out a detailed study of a large young galaxy cluster and they even weighed the mass of the galaxy.
A team of Australian and American researchers have discovered a distant, ancient cloud of gas, which likely contains the elements from the very first stars that formed in the universe.
A trio of bright stars on the outskirts of the Milky Way is racing away from the galaxy and may confirm a method for detecting dwarf galaxies dominated by dark matter.
Scientists may have gotten a glimpse of what life is like on other planets.
The most distant galaxy cluster to be found yet has been identified by astronomers.
The Hubble Space Telescope has spotted an ancient globular cluster 22,000 light-years away in the constellation of Serpens (The Serpent).
Eta Carinae is best known for an enormous eruptions seen in the mid-19th century. Now, scientists have found five similar objects in other galaxies for the first time.
Could you see a black hole with your naked eye? All you need is a 20 cm telescope in order to see a nearby, active black hole, according to researchers.
Globular star clusters can hold a million stars in a ball that's only about 100 light-years across on average. Now, though, scientists have found that these clusters may be good places to look for space-faring civilizations.
