A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

What new methods can be developed in the search for extraterrestrial intelligence (SETI)? This is what a recent white paper ...

Young Pulsar Halo Candidate : Around the 62,400-year-old pulsar J0248+6021, LHAASO detected diffuse gamma-ray emission spanning 29–49 light-years.

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before seen.

These processes can be monitored by measuring the high-energy electromagnetic radiation and particles that they emit including x-rays, ultraviolet light and gamma rays.

A Century-Old Mystery and the Power of PeVatrons Cosmic rays, discovered in 1912, are particles—mostly protons—that travel through space at nearly the speed of light. For over a century, their ...

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

"This discovery heralds a broader understanding of the diversity in massive stars' deaths and a need for deeper ...

The telescope design is a candidate for use in new effort to study high-energy gamma-rays that will involve more than 100 telescopes.

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The ...
