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

Using NASA's James Webb Space Telescope, Technion-Israel Institute of Technology researchers measure cosmic rays in far-off ...

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

Deep inside a nearby galaxy, a black hole sits behind a thick wall of dust. Almost all its light gets trapped.

CERN's ALICE collaboration reveals how fragile deuterons survive high-energy collisions, impacting models of cosmic rays and dark matter.

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, ...

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu ...

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

The path of 14C from cosmic rays to cellulose. Green arrows denote newer pools of 14C and brown arrows denote older pools. The size of the arrow reflects best estimates of size of the carbon pool.

One such cloud is called Barnard 68, located about 500 light years from Earth in the constellation Ophiuchus. Its interior is 9 Kelvin (−264 °C) cold and so dense (and thus opaque) that light can ...
