A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

A quiet shift in the numbers behind the universe’s growth is pushing scientists toward a bold possibility. Two of the cosmos’ ...

Two of the universe's most mysterious particles may be colliding invisibly throughout the cosmos — a discovery that could solve one of the biggest lingering problems in our standard model of cosmology ...

For nearly a century, scientists have been searching for dark matter — the fundamental, invisible substance believed to make up most of the cosmos. After nine decades of sustained effort, a new study ...

Dark matter doesn’t emit, absorb, or reflect light. It’s invisible but supposedly makes up 85% of the universe’s mass.

For decades, scientists have speculated about the existence of dark matter, the invisible substance that makes up most of the universe’s mass. Now, thanks to groundbreaking research using NASA’s Fermi ...

A new experiment called QROCODILE, led by the University of Zurich and the Hebrew University of Jerusalem, has achieved record sensitivity in the hunt for light dark matter. Using superconducting ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

Scientists have used laser-excited thorium-229 to probe for ultralight dark matter, even without a fully built nuclear clock. Thorium-229’s unique nuclear transition offers up to a billion times more ...

A new study from Tel Aviv University has predicted, for the first time, the groundbreaking results that can be obtained from detecting radio waves coming to us from the early Universe. The findings ...

New research suggests that dark matter could gather over vast periods of time at the heart of Jupiter-sized planets, creating black holes that eat these worlds from within. This striking concept may ...
