Astronomers have found that mysterious dark energy may originate in black holes.
While we can’t see inside a black hole, we can spot the intensely bright glowing disc that surrounds one. Now, we might better understand why these discs appear to ‘twinkle’.
The James Webb Space Telescope is providing astronomers with images and data that reveal secrets from the earliest era of the universe.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
Spiral galaxies like M100, pictured here, may hold answers about the nature of dark matter.

A comparison of star-forming galaxies suggests, surprisingly, that dark matter and visible matter do interact – taking us closer to understanding what keeps the galaxies together.
James Webb has peered into the distant Universe.
James Webb has spotted extremely distant galaxies formed soon after the Big Bang, but are they old or young? Or is this the wrong question to ask?
Long before the James Webb telescope brought us these deep field images, artists have been capturing notions of space.
This cluster of galaxies, called Stephan’s Quintet, is a composite image produced from two cameras aboard the James Webb Space Telescope.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.

Recent results cast doubt on dark matter.
The mirror on the James Webb Space Telescope is fully aligned and producing incredibly sharp images, like this test image of a star.

It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.

Next-generation radio telescopes unravel the mysteries of ghostly circles in the sky.

Some black holes are isolated in space and therefore near impossible to detect.
Some stars travel at high speeds through the universe and sometimes leave spectacular clouds of dust and gas in their wake.

Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.
Anyone with an internet connection can search the universe and possibly discover never-before-seen galaxies.

JSWT may be able to discover signs of life on planets around other stars.

It will be a nail-biting wait as scientists launch and deploy the most complex observatory ever built.

Studying the extreme environment of the Virgo Cluster — which comprises thousands of galaxies — helps us learn what factors can affect and start or stop star formation.
There’s a lot we don’t know about galaxies.
We have to look back to the Big Bang to find out.
Flouride is created by Wolf–Rayet stars, here seen in the Milky Way by the Hubble Space Telescope.
Tracing the cosmic origin of toothpaste, scientists got a glimpse into the surprising chemistry of early galaxies.
