The landmark 10th anniversary of the Hubble Space Telescope's Hubble Heritage Project is being celebrated with a "landscape" image from the cosmos.
There's an old saying in astronomy: Galaxies are like people. They're only normal until you get to know them.
These Hubble images offer an unprecedented view of a planetary game of Pac-Man among three red spots clustered together in Jupiter's atmosphere.
Hubble has found an answer to a long-standing puzzle by examining a strong magnetic field around the active galaxy NGC 1275.
NASA's Hubble Space Telescope captured this image of a nebula near star cluster NGC 2074 on Aug. 10, 2008, the day before the observatory completed its 100,00th orbit of Earth.
A new study of globular clusters has found evidence that these hardy pioneers are likely to form in dense areas, where star birth occurs at a rapid rate.
Astronomers have found that so-called barred spiral galaxies were far less plentiful 7 billion years ago than they are today, in the local universe.
These Hubble images offer an unprecedented view of a planetary game of Pac-Man among three red spots clustered together in Jupiter's atmosphere.
Astronomers have found the equivalent of three out-of-sync "clocks" in the ancient open star cluster NGC 6791.
Hubble captures a very thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago.
The Coma Cluster is one of the densest known galaxy collections in the universe.
Astronomers say they have found about half of the universe's "missing" normal matter, called baryons, in the space between galaxies.
Astronomers used Hubble and the W.M. Keck Observatory to study the galaxies as they existed 11 billion years ago.
Astronomy textbooks typically present galaxies as staid, solitary, and majestic island worlds of glittering stars, but galaxies have a wild side.
The Hubble photographed a gamma-ray burst that holds the record for being the intrinsically brightest naked-eye object ever seen from Earth.
