The MeerKAT radio telescope has produced its first light image — even at quarter-strength, it’s already the best of its kind in the Southern Hemisphere.
Abandoned for 25 years, a 12-meter antenna once used during the Cold War is now introducing astronomy students to the radio universe.
NASA is commencing work on the Wide Field Infrared Survey Telescope (WFIRST), the successor to the Hubble and the James Webb Space Telescopes.
Japan’s newest X-ray satellite, Hitomi (formerly Astro-H), promises to reveal the hot and hidden universe.
LIGO scientists have announced the direct detection of gravitational waves, a discovery that won't just open a new window on the cosmos — it'll smash the door wide open.
NASA has assembled the primary mirror for the James Webb Space Telescope, a big step on the way to the telescope’s October 2018 launch.
Gossip is racing around the physics and astronomy community: has LIGO finally heard its first black-hole merger? Here’s the reality.
NASA's new remote observatory located on a windswept island in the mid-Atlantic provides a critical capability for tracking space junk.
An innovative Earth-observing satellite now shows near-daily views of our home planet online.

A proposal released earlier this month calls for a giant orbiting space telescope that may revolutionize astronomy.
With the initial release of the USNO's Robotic Astrometric Catalog (URAT1), astronomers now have precise positions for about 228 million stars in the northern sky. Given my love of stone walls, I've been thinking about building one in the backyard to enclose the flower beds. But I haven't had the gumption to actually buy the…
After 17 years, researchers using the Parkes radio telescope in Australia have identified the culprit behind a mysterious type of radio signal: two on-site microwave ovens.
