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’.
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.
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 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.
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.
Even experts were not prepared for the crispness of the new images from the James Webb space telescope.
Recent results cast doubt on dark matter.
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.
Complementary science will be at the heart of the Square Kilometre Array.
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.
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.
We have to look back to the Big Bang to find out.
Tracing the cosmic origin of toothpaste, scientists got a glimpse into the surprising chemistry of early galaxies.
