Dark Matter

Here's how the biggest thing in the universe could reveal secrets of the smallest things.

We now have a better idea of how big black holes were born in the early universe, a new study reports.

Before the Big Bang, time may have run in reverse.

These tiny subatomic particles, showering down from the depths of space, continue to surprise (and annoy) physicists chasing them.

Astronomers barely know anything about dark matter, but now they know this: It behaves differently in old, dying galaxies than in new, star-forming ones.

Past studies suggested there was less dark matter earlier on in the universe’s history.

As 2019 nears, physicists are hard at work on the next generation of dark matter detectors, and on parsing confusing data from detectors that already exist.

Stars that have been torn from their natal galaxies and now float within huge galaxy clusters can serve as dark-matter probes, a new study suggests.

A summertime sparkle seemed to hint that researchers had found dark matter, but it looks like those scientists were wrong.

Scientists think there's a 'dark matter hurricane' coming, but it's definitely not going to kill you. It's actually kind of exciting.

To study what is accelerating our universe's expansion, scientists will use a new experiment that employs choreographed robots to watch millions of galaxies every 20 minutes.

Mysterious quantum stars that act like single, monster atoms could form surprisingly quickly.

A new map of dark matter all over the universe could reveal things scientists don't know about dark energy.

A remarkable new image from the Hubble Space Telescope captures a close-up view of some of the most distant galaxies in the universe.
