NASA is developing a key instrument for a mission to the Martian moons, Phobos and Deimos.
Rapid-response observations by major observatories shows that the first-known interstellar visitor is 10 times longer than it is wide.
The Zwicky Transient Facility has taken its first image, covering an area equivalent to 247 full Moons in a single shot. This beginning is part of an ongoing sea change in astronomy.
LIGO has detected another black hole merger, raising the tally to five.
A suborbital launch from Wallops Flight Facility tested a critical piece of landing hardware for the Mars 2020 rover.
Astronomers have discovered a potentially rocky planet around a red dwarf star just 11 light-years away.
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.
Early next year, an international team will track the uncontrolled atmospheric reentry of Tiangong 1, China's first prototype space station.
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?
Venus bids farewell at dawn, but not before a close encounter with returning Jupiter.
By watching a star’s disappearance, astronomers learned about the state of the ultrathin atmosphere of Triton, Neptune's largest moon.
Two telescopes — one on the ground and one in space — watched a black hole’s jet turn on, enabling astronomers to probe its origin.
Tantalizing new observations hint that there's a lot more going on in the Proxima Centauri system — the one that hosts the exoplanet nearest Earth — than meets the eye.
Observations from NASA's MAVEN spacecraft reveal that the solar wind causes unexpected interactions with the Red Planet's weak magnetism.
What can we learn from observations made with digital cameras mounted on ~10-cm telescopes? It turns out, a lot about the solar corona.
Just discovered, Comet Heinze (C/2017 T) will zoom by Earth in January and may just show up in your binoculars.
The Moon occults two 1st-magnitude stars for much of North America just six days apart. The first event happens mostly in early-evening darkness, the second in broad daylight — an extra challenge for the adventurous.
Engineers are looking for a way to continue using Curiosity's drill after a 10-month hiatus, but restoring the drill will probably take several more months.
As you'll hear in this month's astronomy podcast, Venus and Jupiter are putting on quite a show low in the east before dawn.
International Observe the Moon Night gathers people together to observe the Moon and to learn more about it. This year InOMN will be on Saturday, October 28th.
An upcoming study will take the old calibration standard of the Moon's brightness to a new level of precision.
Telescopes only picked it up a week ago, but it's likely been traveling through interstellar space for millions of years.
A professional observatory in Greece has begun recording flashes created when bits of interplanetary debris strike the Moon.
See what cosmic dust can do! Head outside this weekend for the peak of the Orionid meteor shower and an eyeful of zodiacal light.
You'd think scientists would have Saturn all figured out after watching it up close for 13 years. They don't.
