LIGO Detects Third Black Hole Merger
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
Seventh TRAPPIST-1 Planet Confirmed
Astronomers have confirmed the existence of the seventh planet around the ultracool dwarf star TRAPPIST-1.
How Hard Did It Rain on Ancient Mars?
Mars was once far wetter than it is now — but just how much rain fell, and when?
Enceladus: Hydrothermal Heating Confirmed
Astronomers have more evidence that the hidden ocean inside Saturn’s moon Enceladus is heated by hydrothermal activity.
Sun Triggers Ceres’ Fleeting Atmosphere
Planetary scientists think the Sun may inadvertently create a transitory, tenuous atmosphere around the dwarf planet Ceres — and in an unexpected way.
Mars Lost Atmosphere to Space
NASA’s MAVEN mission has confirmed that the solar wind stripped the Red Planet of its atmosphere.
Stars Born in Galactic Wind
Astronomers have found newborn stars in gas pouring out of a galactic nucleus.
Seven-Planet Star Hides Age, Might Be Deadly
The star with seven exoplanets puts out enough high-energy radiation to tear away the inner planets’ atmospheres in a few billion years.
Seven Earth-Sized Planets Found Orbiting Dim Star
Astronomers have found seven Earth-sized planets around a cool red dwarf, all of which have the potential for liquid surface water.
Active Black Hole Encourages Starbirth
Astronomers have discovered long filaments of cold gas — the ingredient for making stars — cocooning giant bubbles inflated by a black hole.
Scientists Find Organics on Ceres
The Dawn spacecraft has detected organic compounds on the dwarf planet Ceres.
Cosmic Void “Pushes” Milky Way
Astronomers have discovered a giant cosmic void that explains why our Local Group of galaxies is moving through the universe as fast as it is.
Proxima Centauri b Likely a Desert World
Astronomers suspect the Sun’s closest stellar neighbor desiccated its potentially rocky exoplanet, destroying the planet’s chances for habitability.
Mystery Object in Cygnus A Galaxy
Astronomers have discovered an object in the active galaxy Cygnus A that wasn’t there before.
Voyagers Flying Through Galactic Clouds
Astronomers have combined data from the Voyager spacecraft and the Hubble Space Telescope to probe the stuff between the stars.
Paired Stars in Cygnus En Route to Merger
Astronomers suspect that a binary star system in Cygnus is preparing to make one star of two, erupting in a red nova visible to the naked eye.
What’s Inside a Black Hole?
What’s inside a black hole? Wormholes? Alternate universes? If you fell into a black hole, only one thing’s for sure: its tidal forces would kill you.
