NASA’s Artemis III Lander Test Will be a "Dress Rehearsal" for Returning to the Moon!
Before Artemis astronauts land on the Moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Data from that mission, along with future uncrewed demonstration missions at the Moon,
Submillimeter Array Catches a Gamma-Ray Burst Thanks to new Fast-Response System
The Submillimeter Array's (SMA) new semi-automated alert system demonstrates how the radio interferometer quickly responds to discoveries from space-based telescopes.
On The Hunt For Earth’s First Complex Life

The Dark Energy Camera's New Image is Reminiscent of van Gogh
The Dark Energy Camera (DECam) has a massive 570 megapixel camera, and its new image is of the Corona Australis Molecular Cloud. Corona Australis is one of the closest star-forming regions to Earth. It's not as well-studied as the Orion Molecular Cloud or Ophiuchus, but as DECam's new iage of Corona Australis shows, it's just as fascinating.
What's It Like to Travel Near the Speed of Light? Part 4: The Hot View
An accelerating observer finds their empty vacuum glowing with real particles, a bizarre effect called Unruh radiation. It's a cousin to Hawking radiation, but with no black hole required, just a rocket and its throttle.
