“For example, Chandra’s X-rays reveal the high-energy radiation around the supermassive black hole at the center of M31 as ...

The 21-centimeter signal is a distinct wavelength of radiation that burst right after the Big Bang and could be key to the ...

This stunning Hubble view of spiral galaxy UGC 11397 captures more than graceful arms and glowing stars—it hides a ravenous ...

The origin of lithium (Li), the third element of the periodic table, has long been shrouded in mystery. This element, commonly found in cosmic rays as two stable isotopes, 6Li and 7Li, is crucial ...

Filling in the Cosmic Ray Spectrum Gap What makes this theory especially compelling is how well it fits into a known gap in the cosmic ray spectrum. At lower energies, cosmic rays come from within ...

Cosmic rays may offer an out-of-this-world answer to a long-standing mystery about lightning on Earth, a new study suggests. Thunderstorms are exceedingly common; a staggering 3 million lightning ...

First reported in 1912 by Austrian physicist Victor Hess, cosmic rays were discovered after a series of balloon ascents meant to explore ionizing radiation that was first detected on an ...

Researchers at the Large High Altitude Air Shower Observatory (LHAASO) have accurately measured the cosmic ray all-particle energy spectrum and the mean logarithmic mass in the range of 0.3–30 ...

“The study measured the proton spectrum in cosmic-rays from 50 TeV to 1.3 PeV, effectively connecting observations from both space-based and ground-based measurements,” Mohanty describes. Among the ...

Cosmic rays "have been detected here on Earth for more than 100 years now. Yet, their origin remains largely unknown," Julia Tjus, a professor of physics and astronomy at Ruhr University in ...

The GRAPES-3 experiment in Ooty, India discovered a kink in the cosmic-ray proton spectrum at around 166 tera-electron-volt (TeV). The new feature will advance our understanding of the cosmic ray ...

Cosmic ray found decades ago had 'more energy than was theoretically possible' The most powerful cosmic ray, named the Oh-My-God particle, was detected more than 30 years ago and measured around ...
