Astronomers have made a historic discovery by directly detecting cosmic rays deep inside a dense, starless molecular cloud. This breakthrough provides an invaluable look at the invisible particles ...

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

Astronomers have found a pair of extraordinary cosmic objects that dramatically burst in X-rays. This discovery, obtained with NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton observatory, may ...

But if cosmic-ray immersion is sufficient—and common—then the conditions that helped shape Earth may arise around a large fraction of sun-like stars. Discover the latest in science, tech, and space ...

Some of the most energetic cosmic rays in the galaxy may come from a surprisingly small source. If Max Planck Institute for Astrophysics researcher Laura Olivera-Nieto and her colleagues are right, ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration shows cosmic rays streaming at Earth. Earth is under constant bombardment by high-energy charged particles called ...

The study of cosmic rays and heliospheric physics bridges our understanding of high‐energy particles from distant astrophysical sources and the dynamic environment shaped by the solar wind and ...

Energetic particles that pop briefly into existence when cosmic rays hit Earth’s atmosphere could help assess hidden damage to buildings in Ukraine after the war ends. In the 1970s, a pioneering ...

If recent measurements of cosmic ray particles are correct, then we may have the first evidence that the universe as we know it is really a giant computer simulation. Humans have explored the laws of ...

Georgia State Regents’ Professor of Physics and Astronomy Xiaochun He and his students have developed a detector to measure cosmic rays and investigate how space weather can impact our changing ...
