Dark matter is a hypothetical substance that outweighs regular matter – which makes stars, planets, and everything we can see and touch – by five to one. But we don’t know what it is.

Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have found compelling evidence of a dark matter-deficient dwarf galaxy, FCC 224. This ultra-diffuse galaxy is located on the ...

But in a new study, published in Physical Review Letters, we show that both could be linked to one of the most elusive ingredients in the universe: dark matter. In particular, we propose that a ...

Welcome to the kingdom of the dark. We do not understand what dark matter is, but we know that it exists. The evidence goes all the way back to the 1930s and the efforts of pioneering astronomer ...

For almost a century, scientists have tried to explain this by searching for a hidden force called dark matter. It’s been an idea so accepted that entire models of the universe rely on it.

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build ...

In the 1930s, astronomer Fritz Zwicky named this matter “dark matter,” and in the 1970s, astronomer Vera Rubin discovered indirect evidence of its existence. Scientists theorized that dark matter, ...
