Scientists have released a new survey of all the matter in the universe, which could shed light on the forces that shaped its evolution.

Astronomers have found that mysterious dark energy may originate in black holes.

By spotting and counting tiny galaxies, we can work out how much dark matter is hiding in the cosmos.

Analyzing more than two decades’ worth of supernova explosions, astrophysicists now have the most precise limits yet on the composition and evolution of the universe.

A new technique could improve the precision of atomic clocks and of quantum sensors for detecting dark matter or gravitational waves.

Recent results cast doubt on dark matter.

There’s a perfectly good alternative to dark matter, but most scientists aren’t keen on the idea.

Simulations show some galaxies lose their dark matter in collisions. They show how galaxies can exist without dark matter, once thought impossibe.

Time ends when the universe does.

The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
