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

Want to see cosmic rays? You might need a lot of expensive exotic gear. Nah. [The ActionLab] shows how a cup of coffee or cocoa can show you cosmic rays — or something — with just the right lighting ...

Researchers have detected an extremely energetic cosmic ray from an unknown source in the universe. The detection of a cosmic ray with such high energy is "exceedingly rare" and the latest discovery, ...

Stars and planets form in cold, dense clouds of gas and dust, where cosmic rays are the dominant source of ionization and heating. Cosmic rays are high-energy particles, including protons, electrons, ...

There are plenty of mysteries in the cosmos, and researchers from the University of Utah have found a new clue in one from more than 30 years ago. In 1991, scientists detected a cosmic ray so powerful ...

Where starlight doesn't reach, new things are born: For the first time, an international research team has directly measured ...

An extremely energetic cosmic ray – an extragalactic particle with an energy exceeding ~240 exa-electron volts (EeV) – has been detected by the Telescope Array experiment’s surface detector, ...

Cosmic rays, consisting predominantly of high-energy protons and nuclei originating from distant astrophysical sources, interact continuously with the solar wind and the heliospheric magnetic fields.

It's 1961, and four intrepid cosmic explorers journey to space under the leadership of Reed Richards, where they encounter ...
