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.

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.

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
