Future missions to the Moon, Mars, and beyond will expose astronauts to levels of radiation far greater than those ...

A study published in Physical Review Letters by a research team at Penn State University offers a potential explanation. Led by Kohta Murase, a professor of physics and astronomy, the investigators ...

George Smoot, who shared the Nobel Prize for Physics in 2006 for his studies of the cosmic microwave background (CMB), died on 18 September at the age of 80. Smoot’s work on the blackbody form and ...

The pairs should then scatter on the cosmic microwave background to generate lower-energy gamma rays—yet these have not been captured by gamma-ray space telescopes, such as the Fermi satellite. Up to ...

WASHINGTON — A startup named Cosmic Shielding says it has found a way to close the technology gap that limits how much computing power satellites can carry into orbit. The Atlanta-based company ...

Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult ...

"By reproducing relativistic plasma conditions in the lab, we can measure processes that shape the evolution of cosmic jets and better understand the origin of magnetic fields in intergalactic space." ...

Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental ...

When we gaze up at the night sky, we often marvel at the twinkling stars, distant planets, and expansive galaxies. Yet, beyond the visible spectrum lies a more mysterious aspect of the cosmos—cosmic ...

Natural background radiation coming from cosmic rays, the earth's crust, and food can vary from place to place. Altitude is one factor that plays a role in radiation levels, as does geology. The graph ...
