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 ...

Scientists have identified an accelerator that produces the highest-energy protons in our galaxy, a finding that could clarify the nature of the fast-moving particles filling the space between stars.

Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...

Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help explain where these particles come from. Using the DAMPE space telescope, ...

When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them ...

The first step on the moon was one of humanity's most exciting accomplishments. Now scientists are planning return trips—and dreaming of Mars beyond. And finally, the trip to Mars is planned for the ...

The discovery could transform how researchers monitor and forecast solar storms that have harmful effects on satellites, communication systems, and power grids.

NASA's Artemis I mission takes a selfie of the Orion capsule on its way to the moon. Travel beyond the Earth's atmosphere and magnetic fields involves exposure to high levels of radiation from the sun ...

Juno mission detected particles near Jupiter moving close to the speed of light The discovery helps explain the origin of high-energy particles like cosmic rays Jupiter's larger bow shock accelerates ...

For more than a century, cosmic rays have remained one of astronomy’s lingering puzzles. These tiny particles move through space carrying extraordinary amounts of energy, arriving from distant corners ...
