Three experiments will begin upgrades that could help them corner the particles responsible for the universe’s missing mass
 

David Spergel explains why a widely publicized gravitational-wave discovery could be wrong, and how it could affect the public’s perception of science

The recent discovery of gravitational waves emerging from the big bang may point a way forward

A co-designer of an experiment that might have confirmed gravitational waves isn't bothered by criticism that cosmic dust may account for his results

Cosmic dust is crucial to the birth of stars and planets, but how so much of it came to be present in the young universe has been a mystery

Changes measured by the Swarm satellite show that our magnetic field is weakening 10 times faster than originally predicted, especially over the Western Hemisphere

Theoretical physicist Carlo Rovelli, one of the creators of loop quantum gravity, and his collaborator Hal Haggard have just come out with a new paper on black holes.

A galaxy four billion light-years from us was has three supermassive black holes at its center, with two in a tight formation. Clara Moskowitz reports

Mysterious light at the center of the milky way could be our first look at dark particles

The discovery could help us understand how planets and solar systems form
