Astronomers have used NASA’s Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the “Treble Clef” because its distinct shape strongly resembles the musical symbol.

If you’ve ever had your car start sluggishly, or not at all, on a particularly frigid winter morning, you know standard batteries do not like extreme cold. That’s why NASA researchers are working to develop a battery that could function in the brutal cold of the moon’s south pole, where nighttime temperatures plunge to minus […]

The space industry is rapidly expanding. About 20,000 satellites already circle Earth, a number that could reach 100,000 by 2030. They bring growing environmental costs: space debris, collision risks, atmospheric pollution from launches and reentry and interference with astronomical observations.

A research team from the Kyushu Institute of Technology, Kwansei Gakuin University, Tokyo City University, Kanazawa University, the University of Tokyo and other institutions has successfully completed the test operations conducted since the satellite was released into orbit. Having confirmed that the satellite meets its specified performance requirements, the team has begun routine operations for […]

A commercial lander that will be at the forefront of NASA’s efforts to establish a moon base, humanity’s first lunar outpost, has passed a series of critical tests at the agency’s Jet Propulsion Laboratory in Southern California. The tests simulated the extreme temperatures and vacuum of space, as well as the intense shaking and ear-splitting […]

Turbulence is ubiquitous and occurs every day, such as when milk is stirred into coffee or in the stormy motions of the ocean and the atmosphere. Media in space and astrophysical systems can also develop turbulence, but the physics is different because the medium is in an ionized state (known as the plasma state) and […]

The James Webb Space Telescope (JWST) has detected a possible supernova in the early universe just days after the star exploded. Called AT 2026abck, the transient lies in a star-forming galaxy at a redshift of 5.017 and was found without the help of gravitational lensing. JWST observations suggest the event was caught only about four […]

The speed of an asteroid’s spin can tell astronomers a surprising amount about what it is made of. However, existing approaches to measuring spin based on telescope observations can often produce misleading estimates.
