Just like human eyes, the Hubble Space Telescope can't observe the sun directly - so NASA scientists plan to study Venus's solar transit in June by using the moon as a mirror.
The image snapped by NASA’s Hubble Space Telescope may seem like a quiet patch of sky at first glance.
Astrophysicists at the University of Warwick have identified four white dwarfs surrounded by dust from shattered planetary bodies which once bore striking similarities to the composition of the Earth.
Stars running out of nuclear fuel pass through the preplanetary or protoplanetary nebula stage - a short period in the cycle of stellar evolution that has nothing to do with planets.
Astronomers using the Hubble Space Telescope have for the first time captured images of auroras on the giant ice planet Uranus.
NASA’s Hubble Space Telescope has captured an image of NGC 4980, a spiral galaxy in the southern constellation of Hydra.
Messier 9 can best be described as a globular cluster, a roughly spherical swarm of stars that lies approximately 25,000 light-years from Earth.
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.
