On Jan. 31, 1958, Explorer 1 became the first satellite launched by the United States. Its primary science instrument, a cosmic ray detector, was designed to measure the radiation environment in Earth ...

Since it turned on, the James Webb Space Telescope has revealed dozens of mysterious red blobs in space. The so-called Little ...

It's the second most energetic cosmic ray ever to be detected striking Earth.

Scientists use distant gamma ray bursts to prove that light maintains its constant speed, reinforcing Einstein's theory.

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), ...

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

Research findings are available online in the Astrophysical Journal. The original story “ Student made cosmic dust in the lab revealing life’s early chemical origins ” is published in The Brighter ...

The Mu2e experiment reached an important milestone as the collaboration moved a key component of the experiment, called the ...

Imagine being able to see through walls of steel and concrete without cutting, drilling, or opening a single door. For decades, this has been the dream of scientists and security experts tasked with ...

Watching proteins move as they drive the chemical reactions that sustain life is one of the grand challenges of modern biology. In recent years, X-ray free-electron lasers, or XFELs, have begun to ...

Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It ...
