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.

MISSOULA, Mont. — The sky can produce a plethora of unique and awe-inspiring sights. One phenomenon well worth keeping a watch for often occurs when the sun is low on the horizon. Many viewers have ...

We’ve all seen them before, and what a beautiful sight they are. Those beams of sunlight you can actually see poking through the clouds are called crepuscular rays. The phrase “Crepuscular Rays” ...

A radio telescope in outback Western Australia has been used to observe radiation from cosmic rays in two neighbouring galaxies, showing areas of star formation and echoes of past supernovae. The ...

A cosmic gas cloud has a mysterious gamma-ray "heartbeat" that appears to be in sync with a neighboring black hole. Using data from the Arecibo Observatory in Puerto Rico and NASA's Fermi Gamma-ray ...
