Hubble watches exploding star fade into oblivion

Astronomers using NASA's Hubble Space Telescope captured the quick, fading celebrity status of a supernova, the self-detonation of a star. The Hubble snapshots have been assembled into a telling movie of the titanic stellar blast ....

Very Large Telescope spots galaxies trapped in the web of a supermassive black hole

With the help of ESO's Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole, the first time such a close grouping has been seen within the first billion years ....

Scientists precisely measure total amount of matter in the universe

The team determined that matter makes up about 31% of the total amount of matter and energy in the universe. Cosmologists believe about 20% of the total matter is made of regular -- or "baryonic" ....

Astronomers model, determine how disk galaxies evolve so smoothly

This illustration shows how two sample star orbits are scattered from nearly circular orbits by the gravity of massive clumps within galaxies. Researchers have found that millions of orbital changes, like those shown here, smooth ....

Pair of massive baby stars swaddled in salty water vapor

ALMA composite image of a binary massive protostar IRAS 16547-4247. Different colors show the different distributions of dust particles (yellow), methyl cyanide (CH3CN, red), salt (NaCl, green), and hot water vapor (H2O, blue). Bottom insets ....
