A solar image that self-described UFO expert Scott C Waring says was captured on 3 October has prompted him to claim that a ...

NASA have shed light on a supposed 'alien spacecraft' pictured in one satellite picture, believed by so-called UFO researchers to be around 2.5 metres in length ...

Cosmic rays seen at Earth show a wide range of particle energies, from 10 7 electron-volts (eV) to more than 10 20 eV, the latter being about the same as the kinetic energy of a 450 gram football ...

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better ...

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, ...

Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts of mass, including carbon, nitrogen and oxygen—the building blocks of life.

For more than 60 years, physicists have chased one of the universe's most stubborn puzzles: where do the most energetic particles ever detected come from? A new study published May 7, 2026, in ...

The observation of ultrahigh-energy radiation from a binary star system suggests that such “gamma-ray binaries” could be significant contributors to the cosmic-ray spectrum. LHAASO’s detectors are ...

More than 600 feet below the surface of Antarctica, ultrasensitive detectors picked up the tracks of cosmic rays crashing down from outer space. The Askaryan Radio Array is a group of sensors drilled ...

A solar storm hitting Earth appears to have reduced the amount of incoming high-energy cosmic rays, suggesting a new way of measuring solar activity. Storm alert. A coronal mass ejection was recorded ...
