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…

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…

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…
The SKA is on the horizon, but how do we get from here to there? Pete Wheeler, ICRAR

Aspiration vs delivery: the long road to the Square Kilometre Array

The Square Kilometre Array (SKA) radio telescope has been on the cards since the early 1990s. It took until May of last year to find out where it will be built – in South Africa, Australia and New Zealand…
