A new theoretical study proposes that light from distant galaxies could be slightly shifted in color by interactions with ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

A University of York study suggests dark matter may subtly tint light red or blue as it passes through space, leaving a ...

Scientists working with the Gemini North and Keck II telescopes have discovered a galaxy that's made from 99.99% dark matter. And they noticed it because it was "fluffy." Share on Facebook (opens in a ...

Dark matter is a type of matter that does not emit, absorb, or reflect light, making it invisible to telescopes. Israeli scientists have outlined a groundbreaking method to study dark matter, ...

"It's a fairly unusual question to ask in the scientific world, because most researchers would agree that dark matter is dark, but we have shown that even dark matter that is the darkest kind ...

Dark matter is invisible. It's all around us. And we have no idea what it is. The universe is so much bigger than what people can see. Visible matter — which makes up the things you can see like the ...

"Now there is an intriguing possibility that dark matter may be more complex and vibrant than we expected." When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

Dark matter, the invisible substance believed to account for over 80 percent of the universe’s mass, is not an easy thing to detect. We can see its gravitational pull on visible matter, however — ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...
