Astronomers using NASA's Hubble Space Telescope have found several quasars acting as gravitational lenses, making it easier to study the galaxies in which they're contained.
The numerous faint stars that comprise the Antlia Dwarf galaxy - first discovered in 1997 - are more than four million light-years from Earth.
Astronomers analyzing data from NASA's Hubble Telescope have identified what seems to be a clump of dark matter left behind from a collision between massive clusters of galaxies.
Astronomers using the Hubble Space Telescope have identified a new type of planet - a waterworld surrounded by a thick, steamy atmosphere.
NASA astronomers using the Hubble Space Telescope have found a cluster of young, blue stars encircling the first intermediate-mass black hole ever discovered.
The European Space Agency (ESA) has released new images of the Eagle Nebula, which is located some 6,500 light-years away in the constellation of Serpens.
Astronomers using NASA's Spitzer and Hubble space telescopes have discovered that one of the most distant galaxies known is churning out stars at the rate of 100 per year.
Scientists have discovered new evidence indicating that there may be complex hydrocarbons on the surface of Pluto.
NASA's Hubble Space Telescope has identified 18 "tiny" galaxies which existed 9 billion years ago and are brimming with star birth.
A new technique to study the bright disc of matter surrounding a distant black hole is as precise as spotting individual grains of sand on the surface of the moon.
Astronomers at Rice University have released a movie created from still Hubble Telescope images that shows energetic jets of glowing gas being ejected from young stars.
NASA has concluded that it will cost approximately $8.7 billion to finish construction of the James Webb Space Telescope in time for a 2018 launch.
NASA's Hubble Space Telescope has captured a beautiful picture of a giant cosmic necklace. Aptly dubbed the Necklace Nebula (PN G054.2-03.4), the image shows a recently discovered planetary nebula - the glowing remains of an ordinary, Sun-like star.
Quite by accident, astronomers using the Hubble Space Telescope have discovered a fourth moon orbiting the (dwarf) planet Pluto.
This week, the Hubble Space Telescope turned 21! Shots? Well, not for this special birthday.
Astronomers are poring over data from what they say is one of the most puzzling cosmic blasts ever observed.
Astronomers at NASA are peering ever further away into the universe, and have now discovered their most distant galaxy yet.
Hubble scientists have released a picture of a strange green blob floating near a neighboring spiral galaxy.
New images from the Hubble Space Telescope show an appropriately festive-looking bubble of gas in our neighbouring galaxy, the Large Magellanic Cloud.
Astronomers have long used powerful telescopes to peer into the past. But now, NASA and ESA are using the Hubble Space Telescope to look thousands of years into the future.
