The vast expanse of Western Australia is perfect for radio astronomy. Pete Wheeler, ICRAR

Tuning in to cosmic radio from the dawn of time

The Murchison Widefield Array sits in remote Western Australia far from noisy civilisation so it can help us understand the universe by tuning into radio waves from the distant cosmos.

Darkness is disappearing and that’s bad news for astronomy

Darkness is precious to astronomers, but it's also good for everybody. We should ensure we preserve the dark by using the latest technologies responsibly.

The hunt for ET will boost Australian astronomy

The Parkes radio telescope is part of the US$100 million search for life elsewhere in the universe, but the investment will also benefit other space research at The Dish.

How we found the source of the mystery signals at The Dish

Astronomers used to probing the universe always knew that strange signals detected by the Parkes radio telescope were coming from somewhere closer to home. But finding the source was the tricky bit.

A faster response needed to see Fast Radio Bursts in the universe

Astronomers are trying to improve their hunt for rapid bursts of radio emission in the universe called Fast Radio Bursts (FRBs) so they can better observe these mysterious events, which are thought to…

Let there be light! Celebrating the theory of electromagnetism

It’s hard to imagine life without mobile phones, radio and television. Yet the discovery of the electromagnetic waves that underpin such technologies grew out of an abstract theory that’s 150 years old…
The Mopra telescope will find itself out of commission in a year. Balt Indermuehle

Meet a real interstellar explorer – but its days are numbered

Australia’s Mopra telescope, nestled in NSW’s Warrumbungle National Park, is earmarked for closure in a year thanks to CSIRO funding cuts. But this one-of-a-kind telescope is well worth saving. Few of…
What future for the Parkes radio telescope amid the CSIRO cutbacks? CSIRO/Wayne England

Australia’s astronomy future in a climate of cutbacks

The future looks very bright for Australian radio astronomy but it was somewhat clouded earlier this year when CSIRO’s radio astronomy program took a dramatic hit in the Australian federal budget. CSIRO…

The first images from ASKAP reveal slices through space

The first images from Australia’s Square Kilometre Array Pathfinder (ASKAP) telescope have given scientists a sneak peek at the potential images to come from the much larger Square Kilometre Array (SKA…
The origin of today’s burst of energy has astronomers puzzled. AP Photographie /Flickr

Heavens above! What made the cosmic flash that lit Earth today?

A titanic eruption in our neighbouring galaxy, Andromeda, has sent shockwaves through the astronomical community here on Earth. NASA’s Swift satellite detected a flood of gamma rays at 21:15 UTC yesterday…
We’ve stellar astronomy research programmes and need to keep them up. Flickr/xJason.Rogersx (image cropped)

To reach for the stars, Australia must focus on astronomy

AUSTRALIA 2025: How will science address the challenges of the future? In collaboration with Australia’s chief scientist Ian Chubb, we’re asking how each science discipline will contribute to Australia…
We’ve known about the energetic jets that spew matter from black holes for nearly a century, but what are they made of? NASA

Cosmic jets: what’s shooting out of black holes?

While we tend to think of black holes as giant cosmic vacuum cleaners, it’s not all one-way travel. As gas falls in towards a black hole, it spirals gradually inwards like water going down a plug hole…

Fast Radio Bursts: new intergalactic messengers

How many electrons are there in the universe? That may seem nigh on impossible to calculate – let alone comprehend – but the discovery of a new population of astrophysical events called Fast Radio Bursts…
