The Small Magellanic Cloud galaxy here seen in infrared light, but it looks different when viewed at other wavelengths.
The galaxies, stars and planets in our universe can look very different when you view them through equipment that sees beyond the visible light our eyes can see.

Four star names from Aboriginal Australia have been recognised by the International Astronomical Union. So what are they and where to find them?

Your guide to some of the best meteor showers for 2018. Where to look and when in both the northern and southern skies to catch nature's fireworks.
An artist’s impression of `Oumuamua, assuming it’s a rock.
Scientists looking for signs of alien life from the mystery object passing through our Solar system say they've found nothing "so far".
We’ve only travelled into space in the last century, but humanity’s desire to reach the moon is far from recent.
CSIRO Parkes radio telescope has discovered around half of all known pulsars.
In mid 1967, PhD student Jocelyn Bell at Cambridge University was helping to build a telescope. She went on to discover a little bit of "scruff" - the first evidence of a pulsar.
Blink and you’ll miss it – until the next one.

A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.
The star Betelgeuse varies in brightness.
A new look at some of the oral traditions of Aboriginal Australians shows a deep understanding of three red-giant variable stars, long before European observers.
It’s a bird… It’s a plane… No, it’s an object from another solar system! Astronomers have been scrambling to identify a mysterious object passing through our solar system at a speed of about 160,000 km/h. This NASA file image shows a simulation of asteroids passing the earth.
Astronomers have detected what is believed to be the first interstellar object ever seen passing through our solar system.

The science of red skies can also help us understand how stars form.
Map of all matter – most of which is invisible dark matter – between Earth and the edge of the observable universe.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.

A LIGO team member describes how the detection of a gravitational wave from a new source – merging neutron stars – vaults astronomy into a new era of 'multi-messenger' observations.

Astronomers have finally confirmed the source of the latest detected gravitational waves was the collission of a pair of neutron stars, what they'd been searching for all along.
The Australia Telescope Compact Array in Narrabri, NSW.
All it took was a single email alert to send the world's astronomers searching for the source of the latest gravitational wave detected.
The Zadko telescope was set to study the optical glow following a gamma ray burst.
Efforts to see the afterglow from a neutron star merger were nearly thwarted by bad weather and a cyber attack on an Australian telescope.

The gravitational wave itself is the least exciting part of the announcement from LIGO and Virgo. Observing this new source answers many longstanding questions.

International plan for a lunar space station may lag behind efforts by private companies.
Virgo detector in Italy.
New results from Italy and the US help us better estimate the position of the merging black holes that produced the gravitational waves.

Technology is driving a revolution in the way radio astronomers study the universe, and it could lead to new discoveries.
