Astronomers found molecules of a simple form of sugar, known as glycolaldehyde, around a young star.
Most stars come in pairs. NASA's Kepler space telescope has now confirmed a pair of planets orbiting a pair of stars about 5000 light years from Earth. So we see their light from long, long ago; but not so far away (& very much within our own galaxy)
The brightest planet and the largest star are just the start of the night's sky's extreme objects.
A look at these weird, light-gobbling cosmic monsters.
Periodic nova eruptions from a binary star system is a sign of bigger trouble brewing. Red giant stars donate mass to their white dwarf companions until - over a critical mass - the dwarves destroy themselves in Type 1a supernova explosions.
The two newfound galaxies are spirals with two large companion galaxies, just like our own Milky Way.
Einstein's General Theory of Relativity predicts that in the 'big picture' of the universe, matter is scattered randomly. Australian astronomers conducted the largest ever survey of galaxies on this scale to prove that his theory was correct.
This stunning space wallpaper shows the central region of a beautiful spiral galaxy, Messier 83.
The clusters are located about 170,000 light-years away.
This space wallpaper reveals an artist's impression of galaxy at center of Phoenix Cluster.
Some key facts about the faraway cluster, which may be the most massive ever found.
See images depicting the Phoenix galaxy cluster that is breaking several important cosmic records.
A distant galaxy cluster is smashing records left and right.
How do scientists know the shape of the Milky Way when we can only see it from the inside?
Scientists discovered a pulsar that is fleeing rapidly from the supernova that birthed it.
Dark clouds of dust, called globules, are silhouetted against nearby, bright stars in this space wallpaper. Little is known about the globules, except that they are generally associated with areas of star formation.
The map could help crack the mystery of dark energy and dark matter.
Nearly 400,000 galaxies are represented in an animation derived from the Sloan Digital Sky Survey (SDSS) data release 7. Miguel Arago and Alex Szalay of John Hopkins University and Mark Subbarao of the Adler Planetarium created this amazing view.
