Thanks to X-ray telescopes, scientists in the 1970s found the first real evidence that black holes actually existed, and astronomer Andrew Fabian has used X-ray research to unlock incredible mysteries ever since, including a giant sound...

Models of the universe’s early days have only been possible with dark matter as a variable, but we still don’t have proof that dark matter exists. But recently, scientists may have found a way to replicate the results without the...

In a fun, exciting talk, teenager Henry Lin looks at something unexpected in the sky: distant galaxy clusters. By studying the properties of the universe's largest pieces, says the Intel Science Fair award winner, we can learn quite a...

The first full-color images from the James Webb Space Telescope are finally here! Let's take a look, talk about what we're seeing, and compare them to the most detailed version of these images we had before.

Take a tour of the Hydra I galaxy cluster. A galaxy in the region, NGC 3312, is "losing cold gas as it moves through the hot gas within the cluster," according to the European Southern Observatory.

Dark Flow. We investigate why hundreds of galaxy clusters are rapidly drifting towards a specific point just outside the known universe.

Gravitational microlensing events are revealing the mysteries of rogue planets, but what are they, and how does it work? And what role does the Nancy Grace Roman Space Telescope play in helping us spot more rogue planets in the future?

Okay, so we are about 150 million years into the lifetime of the universe. We've got a bunch of hydrogen and helium and not much else. But then gravity takes over, and boom! We've got stars! How, you ask? Well you'd better watch this!

Gravitational microlensing events are revealing the mysteries of rogue planets, but what are they, and how does it work? And what role does the Nancy Grace Roman Space Telescope play in helping us spot more rogue planets in the future?

Astronomers seem to have revealed a puzzling detail in the way dark matter behaves.

They found small, dense concentrations of dark matter that bend and magnify light much more strongly than...
