Asteroid 20223 BU’s path in red, with green showing the orbit of geosynchronous satellites.
Discovered less than a week ago, the truck-sized asteroid skimmed much closer to Earth’s surface than most satellites.
Discover how a picture of the sky can become a symphony.
Chandra X-ray Observatory
Since ancient times, the stars have been set to music. Modern technology now enables scientists to convert images of space into real compositions.
Combined images from the ASKAP and Parkes radio telescopes.

Our galaxy should be full of traces of dead stars. Until now, we have found surprisingly few of these supernova remnants, but a new telescope collaboration is changing that.
The James Webb Space Telescope began sending its first images back to Earth in the summer of 2022.

NASA has been gaining momentum in recent years as investment into space has ramped up in the US. In 2022, missions dealt with the farthest, closest, hottest and coldest conditions in the universe.
The sky looks blue on a sunny day – but at night we can see the faint glow of its true colour.
The Carina star-forming region imaged by the JWST.
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.
When two neutron stars merge and create a black hole, they produce a powerful blast of gamma rays.

Gamma-ray bursts occur when a massive star explodes or when two neutron stars merge. A newly discovered burst has puzzled astronomers, as it lasted much longer than astronomers would have expected.
Stonehenge has long been the site of some of the most famous solstice celebrations.

The dead of winter, when the longest night of the year takes place, has also traditionally been celebrated as a time of renewal and reverence.
Your zodiac sign – like Sagittarius, the archer – might be in the stars, but your future isn’t.

Astrology and astronomy were once practiced side by side by scientists like Galileo and Kepler. And they’re more similar than you might think.
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.
Astronomers have unpacked the mystery of how one star’s death created the nebula NGC3132 – never before seen in such detail.
Trail from BlueWalker 3 above Kitt Peak telescope in Arizona.
The stars, planets and Milky Way we see at night are part of a wilderness shared across the globe and across centuries. But does BlueWalker 3 herald a night sky polluted with bright satellites?
A new particle accelerator at Michigan State University is set to discover thousands of never-before-seen isotopes.
Facility for Rare Isotope Beams
A new particle accelerator has just begun operation. It is the most powerful accelerator of its kind on Earth and will allow physicists to study some of the rarest matter in the universe.
A new study of ‘solar twins’ shows a fundamental constant appears to be the same throughout our local galactic neighbourhood.
People across Australia and New Zealand will be able to catch the blood moon. Here’s how to get the best view.

The IceCube telescope near the South Pole has received a first glimpse into the core of the galaxy NGC 1068.
Believe it or not, this sort-of happened before in Earth’s history – and now we have the Moon.
Astronomers have been looking for radio waves sent by a distant civilization for more than 60 years.

The binary star WR140 is surrounded by an astonishing array of nested shells of dust swirling into space.
In some African countries, astronomical research is quite developed.
