Now out in space for more than two years, the James Webb Space Telescope is a stunningly sophisticated instrument.
Space telescopes are limited in size due to the difficulties and cost of getting into orbit. By revamping an old optical technology, researchers are working on a lightweight and thin telescope design.
A spacecraft set to launch this year will throw a spotlight on the mysterious ‘dark side’ of the universe.
A year on since the historic launch of the most powerful infrared telescope in human history, we admire and explore some of the best images it delivered in 2022.
Through direct comparison with images from Hubble, you can start to see the exquisite detail and clarity Webb provides.
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.
Sagittarius A* lies in the southern sky, passing directly above South Africa.
The telescopes primary mirror segments are now working together to provide a single, sharp image.
Cape astronomers were responsible for, among other things, the first measurement of the distance to a star; the first photographic sky survey and the accurate measurement of the distance to the sun.
There’s an extensive range of telescopes, mounts and accessories on the market, and trying to pick from it might have you seeing stars. Here’s what the experts suggest.
Like a cosmic butterfly in the sky, radio galaxy PKS 2014-55 was observed by CSIRO researchers with the Australian SKA Pathfinder telescope.
Two defunct satellites passed within metres of one another, prompting renewed focus on the dangers of space debris. But with many satellites treated as military secrets, how do we track the hazards?
‘The size, the grandeur, the peacefulness of being in the dark’: what it’s like to study space at Siding Spring Observatory

Three hours north-east of Parkes lies a remote astronomical research facility, unpolluted by city lights, where researchers are trying to unlock some of the biggest questions about our Universe.
Scientists turned Earth into one giant telescope to capture the uncapturable.
The Swift Observatory passed a milestone: 1 million snapshots of the universe. These exquisite and revealing pictures have captured the births and deaths of stars, gravitational waves and comets.
Science and art meet on the ‘big screen’ – turning data into visuals at the Lovell Telescope, Jodrell Bank.
A team of astronomers captured the moment when a wayward star was pulled into the mouth of a supermassive black hole.
When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase as Kepler retires.
The number of known exoplanets doubled this week to more than 3,200. But why have only a handful of these those new planets caught people’s imagination?
