Invisible radiation leaking out of private satellites, like SpaceX's Starlink spacecraft, is disrupting radio astronomers' ability to detect important signals from across the universe. If left unchecked, we could reach an "inflection point" beyond which we can no longer properly study the cosmos, researchers warn.

First theorized in 1938, heat's wave-like flow through superfluids, known as "second sound", has proven difficult to directly observe. Now, a new technique has finally done it, and could be used to study neutron stars and high-temperature superconductors.

A NASA-funded plan to build a large radio telescope on the moon's far side is nearing final approval and could become a reality by the 2030s, researchers say. The ambitious project will help safeguard astronomy from satellite "megaconstellations" — and help scientists unravel more of the radio spectrum.

The number of satellites orbiting Earth is rising fast, thanks to private companies such as SpaceX. But just how big will these "megaconstellations" become? And what problems might they cause?
