An international team of researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP) has shed light on a ...

A new study suggests the Milky Way’s gamma-ray glow could be a dark matter signal shaped by ancient galactic mergers.

A gamma ray glow at our galaxy’s center has puzzled scientists for almost two decades. New computer simulations back the ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

Astronomers have shed light on a decades-long debate about why galaxies rotate faster than expected, and whether this ...

An unexpected monster black hole was found hiding inside one of the Milky Way's tiniest neighbors, rewriting what scientists ...

As a kid, did you ever play that game Guess Who? If you haven't, it's actually kinda fun. You have two players, each with a board in front of them. On the board are a bunch of flip cards with ...

Something seems to be missing from the universe, and the favored model of physics calls it “dark matter” – but despite a century of searching, it remains a no-show. A new paper proposes an alternative ...

An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

A team of astronomers have found a mysterious object in the distant universe that could be dark matter or an inactive smaller, or dwarf, galaxy.

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...
