Comet 67P’s nucleus was born when two became one.
New maps from NASA’s Dawn spacecraft reveal more about both the landscape and composition of the largest asteroid.
Scientists have confirmed that water-soaked salts likely create dark seasonal lines on Mars.
Astronomers think a bright X-ray source in the galaxy NGC 1313 is a mid-size black hole.
Astronomers have confirmed that the quasar PG 1302-102 is probably a binary supermassive black hole, its members less than a tenth of a light-year apart.
Astronomers have detected waves working together in the solar atmosphere, potentially heating the gas through turbulence.
The latest image from NASA's Dawn spacecraft reveals structure in the bright spots on the asteroid 1 Ceres.
Astronomers have discovered that one galaxy of a nearby double-galaxy system has a giant, star-studded ring.
Astronomers have identified the smallest supermassive black hole ever detected in a galaxy’s center.
Astronomers have found that a massive filament of gas in the early universe actually seems to be a humongous, galaxy-forming disk.
Astronomers have confirmed the existence of an exoplanet found via microlensing — the first time they’ve been able to successfully follow up on this method.
