Astronomers have made a historic discovery by directly detecting cosmic rays deep inside a dense, starless molecular cloud.

For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its outer surface. Using the High Altitude Water Cherenkov Observatory (HAWC), ...

Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

The traditional astrophysical recipe for life as we know it is quite simple: Get a rocky, gas-shrouded world in a “habitable zone” orbit around a star so that it’s not too hot or too cold. Then just ...
