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 ...

The Van Allen Probe A, a 1,323-pound NASA satellite that once studied how the Van Allen radiation belts protect the planet from cosmic radiation and space weather, is expected to re-enter Earth’s ...

Cosmic voids are different. These vast expanses contain very little matter. In such places, the vacuum of space-time itself becomes the dominant component. If you were positioned at the center of a ...

Originally built for a two-year mission, the probes collected vital data on the Van Allen belts, which shield Earth from cosmic radiation and solar storms. The mission ended in 2019 when the ...

Astronomers have discovered the brightest and most distant "megamaser" to date. The cosmic energy beam is shooting toward ...

For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo ...

When electronics meet cosmic rays, bad things can happen. Chip makers need to test what their products can withstand, and ...

Estimate your cosmic radiation dose during a flight HERE. For nearly three decades, 52-year-old Sara Nelson has been exposed to radiation every time she goes to work — a risk shared by hundreds of ...

The universe is a place of unimaginable beauty and wonder—shimmering galaxies that dance across the cosmic stage, nebulae ...

Space is tough on materials. Radiation, UV light, atomic oxygen and sharp temperature swings can degrade metals, polymers and coatings over time. This article looks at the current ways researchers are ...
