cosmic ray

Since extreme temperatures and cosmic rays break down rubber or turn it to a brittle glass, metal alloys and high-performance plastic are chief contenders for airless space tyres.

Researchers put detectors deep underground to shield them from cosmic rays and background radiation.

Tracking lines arc through the expansive field, recalling cosmic rays shooting across a cloud chamber.

Inspired by his doctoral adviser, John A. Simpson, Dr. Stone performed his first cosmic ray experiments in 1961 while working on Discover 36, an Air Force spy satellite.

Now that the spacecraft is outside the Sun’s protective bubble, its electronics are also vulnerable to strikes from galactic cosmic rays, charged particles accelerated to ultrahigh energies by supernovae and other cosmic engines.
