Astronomers announce the discovery of bloated gas giant KELT-9b, the hottest "hot Jupiter" exoplanet known orbiting a short-lived massive star.
The most comprehensive and detailed exoplanet catalog released yet marks the end of an era for Kepler, the planet-hunting telescope.
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.
An unusual dawn total lunar eclipse presents special challenges and great photo opportunities. Here's what you need to know to make the most of it.
The dust storm on Mars that broke out at the end of May is now affecting the skies across the entire planet.
They look like leftover gravel from a freshly laid asphalt road, but the black stones that spattered across the snow in the wake of the January 16th Michigan fireball were anything but terrestrial. They belonged to a tiny asteroid on a recent foray to the outer asteroid belt but now grounded for good on Earth.…
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.
The Kilopower fission reactor will offer a more efficient and more powerful portable power source for solar system exploration.
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.
