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 ...

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 ...

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).

Astronomers have worked out the colour of the Universe — and it's a shade between aquamarine and a pale turquoise. This is the colour resulting from a 'census' of light from 166,000 galaxies, captured ...

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 ...

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 ...

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 shape of the spectrum of cosmic ray electrons in the 100 GeV range and beyond can provide information about a variety of problems in cosmic ray astrophysics. The differential energy spectrum ...

With its jewel-like star clusters, swirling galaxies and orange Suns, pictures of the universe are usually impossibly beautiful and brightly coloured. But as Nasa has pointed out the real colour of ...

Nothing gave me more pleasure recently than the reported discovery that the universe is turquoise. What made this pleasurable was not the colour itself, so much as the fact that it is not a colour you ...
