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

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

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

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

“It’s very slow, but over billions of years, it’s a very strong effect.” That is the main surprise of the observations of the ...

Francesca Capel and Nadine Bourriche analyze the most energetic particle that has ever hit Earth and its possible origin in ...

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

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, ...

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

A jetliner was nearly knocked out of the sky and sent plummeting to a deadly crash that would have killed all onboard by a bizarre attack from outer space – an explosive burst of cosmic rays sent ...

We show how this "cosmic clock" uncovers the evolution of rivers, coasts and habitats.

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 ...
