Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
LIGO has detected another black hole merger, raising the tally to five.
The 2017 solar eclipse could easily be the most watched event in US history. Can we learn something from it?
A new study of data archived from the Galaxy Evolution Explorer (GALEX) spacecraft is revealing just how hard life might be on planets like those in the TRAPPIST-1 system.
Following the release of the 2018 budget, the space agency has ordered an “orderly closeout” for the Asteroid Redirect program.
A suborbital launch from Wallops Flight Facility tested a critical piece of landing hardware for the Mars 2020 rover.
A recent NASA study outlines possible dedicated missions to the "ice giant" planets Uranus and Neptune that might leave Earth as early as 2030.
NASA's Parker Solar Probe, set to launch in 2018, will be humanity's first effort to "touch the Sun," revolutionizing our understanding of the Sun's corona, the solar wind, and the greater heliosphere.
The European Space Agency has released its investigation into the crash of the Schiaparelli Mars lander in October 2016.
Russia's first crowd-funded satellite, named Mayak (Russian for "beacon of light"), promises to be the “brightest object in the night sky next to the Moon.”
Are astronomers being misled about a possible ninth planet by the quirky alignment of orbits that they’re finding in the distant Kuiper Belt?
Astronomers have discovered a potentially rocky planet around a red dwarf star just 11 light-years away.
Astronomers may have watched a star collapse directly into a black hole — minus the supernova. The failed supernova could help understand how stars die.
A team of astronomers has taken a close look at a nearby galaxy — and discovered an unusual structure that sheds light on supermassive black holes’ relationships with their host galaxies.
Enrich the eclipse experience — especially the long, partial phases — with solar eclipse activities for kids and families.
Astrobiology students cultivated leafy greens, sweet potatoes, and even hops in simulated Martian dirt.
Think the total solar eclipse is "sold out"? Think again — and grab your camping gear. Private campsites and RV parks within the long path of totality are still available for those willing to travel.
Astronomers have found what could be the closest known pair of supermassive black holes detected via direct imaging, orbiting each other only a light-year apart.
Our galaxy's center region is producing gamma rays, but astronomers are still debating whether pulsars or dark matter are the source. Three recent studies tackle the debate head-on.
Observations of a stellar explosion that refused to fade away have astronomers scratching their heads. What created the blast — and could it explain massive black holes?
The celestial event of this young century — the great American total solar eclipse of 2017 — is now just weeks away. The biggest remaining question is, where will you be when the Moon’s shadow arrives?
In addition to clogged roads and crowded hotels, the 2017 solar eclipse had another big effect on U.S. infrastructure: reduced solar power production.
The arrival of an object from beyond the solar system caught astronomers by surprise — but that doesn't mean that they were unprepared to study it.
NASA engineers directed the historic spacecraft Voyager 1 to fire its backup thrusters for the first time in 37 years.
The Great American Eclipse may be over, but there are some exciting places around the globe getting ready for their own dances with darkness.
