The U.S. Federal Communications Commission can approve massive spaceflight projects on its own, even ones that could permanently change how the night sky looks for everyone on Earth. Space law experts note that despite protests from astronomers and dark-sky advocates, the agency is effectively the only gatekeeper, leaving little room for other authorities to block or shape such projects.

Astronomers report 'groundbreaking' observations of a dead, collapsed star that repeatedly flashes toward Earth as it wobbles, with the pulsing apparently driven by a huge outflow of gas — described colorfully as a giant cosmic 'fart'. The findings offer a rare look at the behavior of a stellar remnant and the material it expels.

An astronomer is tracking how Starlink satellites gradually sink in their orbits, using the drag they experience to measure the density of Earth's upper atmosphere. The approach turns a common headache for astronomers — the growing swarm of satellites — into a global measuring instrument, a 'planetary barometer' for atmospheric conditions that affect satellite lifetimes and space operations.

Researchers have reported detecting a direct radio signal from a planet outside the solar system for the first time. The announcement is being widely shared as a potential milestone in the study of exoplanets, since radio emissions have previously been observed mainly from stars and other cosmic objects rather than from planets themselves. Details about which planet was involved and how the signal was confirmed have not yet been widely reported.

Harvard scientists report detecting a radio signal apparently coming directly from a planet outside the solar system. If confirmed, it would be a rare example of a radio emission traced to an exoplanet, possibly generated by the planet's magnetic field interacting with its star. Astronomers say such detections could open a new way to study distant planets, though further observations are needed to verify the signal's origin.
