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

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

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), ...

What appears to be a ghostly hand reaching across the universe toward a defenseless spiral galaxy in a new telescope image is a rarely seen cosmic phenomenon, according to astronomers. The Dark Energy ...

Astronomers have spotted six rogue worlds, or cosmic objects that don't orbit stars, using the James Webb Space Telescope. The celestial bodies are slightly bigger than Jupiter, and the observations ...

Where starlight doesn't reach, new things are born: For the first time, an international research team has directly measured the effect of cosmic radiation in a cold molecular cloud. The observation ...

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 ...
