The cosmic microwave background (CMB) is the oldest light in the Universe, emitted approximately 380,000 years after the Big Bang. It is microwave radiation that uniformly fills space, a witness to ...

Background: Galactic cosmic radiation (GCR) is a naturally occurring environmental radiation that originates from outer space. GCR is modulated by solar activity, and its intensity increases with ...

☢️👁️ Hardware for a hackable DIY gamma-ray spectrometer using a popular NaI(Tl) scintillator, SiPM and a Raspberry Pi Pico.

Scientists believe that extended exposure to zero gravity, cosmic radiation, and alien environments could drastically alter how animals evolve. Over generations, could space-born creatures become ...

New research by the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe's infancy—the earliest cosmic time yet accessible to humans. Measuring ...

The map shows the cosmic microwave background (CMB), a faint remnant radiation from the early stages of the universe. It began as the earliest light just 380,000 years after the big bang ...

Could some animals be tapping into cosmic radiation for survival? Scientists are exploring whether certain microbes, fungi, and even deep-sea creatures have adapted to use high-energy space ...

He concluded that penetrating radiation was entering the atmosphere from above. He had discovered cosmic rays. These high-energy particles arriving from outer space are mainly (89%) protons – nuclei ...
