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 ...

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 ...

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 ...
