The astronomers Michel Mayor and Didier Queloz won half of the prize for their 1995 discovery of a Jupiter-like planet orbiting a nearby star. The cosmologist James Peebles won the other half for work exploring the structure of the universe.
New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.
A strange glow coming from the Milky Way’s center was thought to be due to ordinary pulsars. But a new look at a years-old study shows that dark matter might still be responsible.
Priyamvada Natarajan has pioneered the mapping and modeling of the universe’s invisible contents, especially dark matter and supermassive black holes.
Astronomers couldn’t find enough satellite galaxies orbiting the Milky Way. Now they have the opposite problem.
Dark matter may occasionally interact with minerals in the earth, leaving telltale tracks that physicists hope to decipher.
A scientist and programmer with a literary bent, Valeria Pettorino thinks multiple angles and diverse points of view are needed to unriddle the nature of dark matter and dark energy.
Computer simulations have become so accurate that cosmologists can now use them to study dark matter, supermassive black holes and other mysteries of the real evolving cosmos.
A roundup of some of the most important discoveries gleaned so far from the Gaia space observatory’s new map of the galaxy.
