NASA has released an amazing composite image of NGC 6357, a region where radiation from hot, young stars is energizing the surrounding gas and dust. This...
Astronomers have used the Atacama Large Millimeter/submillimetre Array (ALMA) to observe the early stages in the formation of a new star system. For the...
ASASSN-15lh, an extremely bright explosion in a massive galaxy 3.82 billion light-years away, was thought to be the most luminous supernova ever seen....
Astronomers have used CSIRO’s Australia Telescope Compact Array (ATCA) and NASA’s Chandra X-ray Observatory to show that a recently-discovered lensed...
Kepler 11145123, a slowly rotating star roughly 5,000 light-years away, is the most spherical natural object ever measured, more spherical than the Sun,...
A multinational team of astronomers has spotted a brown dwarf orbiting a K-type dwarf star approximately 16,300 light-years away. The object was discovered...
New observations with SPHERE, an advanced exoplanet-hunting instrument on the Very Large Telescope at ESO’s Paranal Observatory, have revealed striking...
An international team of astronomers has discovered a giant extrasolar planet orbiting a young star called CVSO 30. Not only have the scientists detected...
Astronomers using observations from NASA’s Kepler and Swift space observatories have spotted 18 fast-spinning stars that produce X-rays at more than...
A triple protostar system surrounded by a disk with a spiral structure has been observed by astronomers using the Atacama Large Millimeter/submillimeter...
Astronomers using ESO’s Very Large Telescope Interferometer (VLTI) in Chile have snapped the most detailed image ever of the Eta Carinae stellar system.
This...
The Sun’s nearest stellar neighbor, Proxima Centauri, has a regular cycle of starspots, according to a team of astronomers from the Harvard-Smithsonian...
Astronomers using ESO’s VISTA infrared survey telescope have discovered a dozen ancient stars, of a type known as RR Lyrae, in the vicinity of the center...
A rogue black hole has been found in the outer regions of the lenticular galaxy SDSS J141711.07+522540.8 (GJ1417+52 for short). Evidence suggests this...
Planets form from epic collisions between asteroids and even bigger bodies, called protoplanets. Sometimes the colliding bodies are ground to dust, and...
This detailed view of the reflection nebula Messier 78 was taken with the Visible and Infrared Survey Telescope for Astronomy (VISTA) at ESO’s Paranal...
Astronomers using the Atacama Large Millimeter/submillimeter Array have detected a pair of trailing symmetric spiral arms in the protoplanetary disk surrounding...
