Astronomers spotted lone planet KMT-2024-BLG-0816 when, like a cosmic lens, it amplified the light of a background star. The planet passed so close to the line of sight that it was possible to see how the brightness of different edges of the stellar disk changed. They didn't find a host star nearby,

If neutron stars had tiny bumps, they would constantly hum with gravitational waves. Using LIGO, scientists searched for that hum from 34 pulsars, the largest search of its kind. No signals were found, which pushes the theoretical limits even lower. The Crab pulsar, for instance, turns less than 0.0

The updated GWTC-5.0 catalog includes 161 recent gravitational-wave bursts from black hole collisions. Thanks to improved detector sensitivity, some signals are now record-breakingly clear, allowing for more precise measurements of black hole masses and stricter tests of relativity. The total number
