Kinky particles: the GRAPES-3 experiment in Ooty, India depicted with a simulated cosmic ray shower. The inset shows the cosmic ray proton spectrum measurement by GRAPES-3 along with observations by ...

When you look up at the night sky, it seems deep black with bright stars scattered across it. That familiar view leads many ...

Researchers have succeeded in the direct, high-precision measurements of cosmic-ray electron spectrum up to 4.8 TeV, based on observations with the Calorimetric Electron Telescope (CALET).

In January, two astronomers captured the world’s fascination when they announced that the universe’s collective color is a pale shade of green. However, this cosmic tint didn’t sit right with some ...

The Universe may appear like a vast expanse of darkness but the average colour is actually beige, according to scientists. They studied the colour of light emitted by 200,000 galaxies to see what the ...

Long-term study The HESS observatory in Namibia has made a “unique measurement” of the electron and positron cosmic ray spectrum. (Courtesy: Klepser/DESY/HESS collaboration/CC BY-SA 3.0) A new ...

For the first time, scientists have watched high‑energy cosmic rays at work deep inside a thick cloud of gas, not just at its outer surface. Using the High Altitude Water Cherenkov Observatory (HAWC), ...

WASHINGTON -- When Mother Nature decorated the universe, she chose a color slightly greener than a pale, pale turquoise. And like an ordinary human homeowner, she'll redecorate eventually, shifting to ...

Galactic cosmic rays (GCRs) are energetic particles traveling across the Galaxy as high-energy beams, and are a unique probe to explore the astrophysical particle accelerators and the interstellar ...
