Stars are giant, luminous spheres of plasma. Galaxies consist of stars, stellar remnants, dust, gas, and dark matter, bound together by gravity. Learn more about stars and galaxies.
A celestial triangle made up of the moon, Mars and Regulus can be seen in the sky early Saturday morning.
The Carina nebula's cold dusty clouds are host to some of the most massive stars in our galaxy.
The Milky Way and its neighbor, the Andromeda galaxy, seem to be slowing down their rates of star formation.
Properties of asteroid Lutetia have been found to be similar to the original material that formed the Earth. The animation depicts what is thought to have caused its drastic change in orbit to now reside in the asteroid belt between Mars and Jupiter.
Astronomers were surprised to find no traces of heavy elements in these primordial gas clouds.
The universe's first stars were not as massive as previous theoretical models predicted.
Zoom into the Hubble GOODS South Deep (GSD) field, observers see "extreme emission line galaxies." GOODS combines deep observations from Spitzer, Hubble, Chandra, Herschel and XMM-Newton.
The 69 tiny, ancient galaxies are forming stars much faster than expected.
Mars pays a visit to the brightest star in the constellation Leo tonight.
All the pulsars – with the exception of one found by the Fermi Gamma-Ray Telescope – are a billion years old or more. A recent discovery has found one that is only 25 million years old and is still packing a lot of pulsing gamma-ray punch.
Two early galaxies were found to contain more heavier chemical elements than was previously thought possible.

The night sky above the 2600-metre-high Cerro Paranal in the Atacama Desert in Chile is dark and clear in this space wallpaper.
The first image of a sun-like star that's surrounded by spiral-arms makes scientists think that planets lurking within are the cause. Such worlds could space-scape gas and dust into arms, rings and lanes.
The European VISTA telescope has found two clusters of ancient stars in our Milky Way galaxy.
