Black hole merger confirms Hawking's area law

A clear signal from the merger of two black holes, each about 33 solar masses, confirmed Hawking's theorem: the final horizon area turned out larger than the sum of the initial ones. This strengthens the link between black hole area and entropy.

Star explosions accelerate particles to record energies

The LHAASO observatory studied gamma-ray emission from supernova remnant IC 443 and found that particles there are accelerated to record energies with no signs of slowing down. This is direct confirmation: it's star explosions that produce the most energetic cosmic rays bombarding Earth.

Solar Storm Illuminated Magnetic Fields in Space

Usually, cosmic rays arrive evenly from all directions, but when the Sun ejects a magnetic cloud, their paths bend. On November 4, 2021, the LHAASO observatory caught a temporary lopsidedness, offering the first-ever glimpse of invisible magnetic structures in interplanetary space.

Tuning Into the Hum of Spinning Stars

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

Record Haul: 161 Black Hole Mergers in Gravitational Waves

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
