NASA astronauts Suni Williams and Butch Wilmore were selected for the first crewed test flight on Boeing's Starliner and were ...

The recent discovery of a stupendously powerful neutrino has left scientists scratching their heads. New research suggests it ...

This is the radiation produced when electrons and positron pairs decay ... Collisions between certain subatomic particles can ...

Detecting radiation is a fundamental necessity for national security, but doing so effectively and at a distance is a tall ...

Two bands of radiation called the Van Allen belts encircle Earth. After a May 2024 solar superstorm, two more showed up between those belts.

Relatively dense, the hydrogen-laden H 2 O molecule can slow down radiation particles as they zip past. Plus, water is something that astronauts will have to bring lots of on deep space missions.

Researchers have found a way to use tardigrade proteins to potentially revolutionize cancer treatment and space travel.

Emily Mason, a heliophysicist at San Diego-based research firm Predictive Science, and her colleagues observed coronal loops ...

That's where radiation therapy can help. It uses high-energy particles to make tiny breaks in the DNA of cancer cells to destroy or damage them, so they can no longer make new copies. The aim is ...

Blazars are active galaxies that emit narrow jets of ionized matter from their centers, aimed towards Earth. Depending on ...

Researchers said alpha particles are promising therapies that target cancer while minimizing the damage to nearby healthy tissues.
