NASA uses moon as mirror to watch Venus transit sun

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.

Hubble sees the eye of a galactic storm

The image snapped by NASA’s Hubble Space Telescope may seem like a quiet patch of sky at first glance. 

These dwarf stars consume exoplanets

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.

This nebula is running out of nuclear fuel

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.

Hubble snaps auroras on Uranus

Astronomers using the Hubble Space Telescope have for the first time captured images of auroras on the giant ice planet Uranus.

This spiral galaxy is in the Hydra Constellation

NASA’s Hubble Space Telescope has captured an image of NGC 4980, a spiral galaxy in the southern constellation of Hydra.

The glittering stars of Messier 9

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.

Quasars found acting as gravitational lenses

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 stars of the Antlia Dwarf galaxy

The numerous faint stars that comprise the Antlia Dwarf galaxy - first discovered in 1997 - are more than four million light-years from Earth.

Dark matter core remains an enigma

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.

'Waterworld' planet discovered

Astronomers using the Hubble Space Telescope have identified a new type of planet - a waterworld surrounded by a thick, steamy atmosphere.

This black hole came from a shredded galaxy

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 Eagle Nebula redux

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.

Ancient galaxy seen creating two stars a week

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.

Complex molecules discovered on Pluto

Scientists have discovered new evidence indicating that there may be complex hydrocarbons on the surface of Pluto.

NASA's Hubble observes "tiny" galaxies bursting with stars

NASA's Hubble Space Telescope has identified 18 "tiny" galaxies which existed 9 billion years ago and are brimming with star birth.

Hubble directly observes a black hole accretion disk

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.

Video: Hubble, supersonic jets & newly formed stars

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 wants $8.7 billion to launch new telescope

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.

Hubble snaps pic of Necklace Nebula

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.
