By sharing a location with the SKA, HIRAX will be able to conduct science in “radio-clear” skies across its wide frequency range.

From a mysterious energy of empty space to parallel universes, cosmology’s view of ‘nothing’ is anything but boring.
New observations show we don’t really understand the universe’s expansion.
The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
Cosmologists who were hoping to be the next Einstein have had to bin their theories.
Controversial new study challenges contemporary thinking about what the universe is made of.
We still can’t see the dark matter thought to make up about a quarter of the universe, but at least now we have a map of its structure.
Is dark energy just an illusion, as is often suggested? To resolve the dilemma, interpreting the basic principles of general relativity in a complex Universe may need a rethink.
The universe is expanding faster than expected, but we don’t know what’s driving it. Here are a few of the possible explanations, from dark energy to a modification of general relativity.
Dark energy is a completely unknown source making up 70% of the universe. Will any of the new projects designed to find out what it is succeed?
Astronomers think they may have found evidence within our galaxy of some of the missing matter thought to make up our universe.
Confirmation bias, the psychological effect that makes people unconsciously interpret information to confirm their beliefs, is a big threat to cosmology.
A unique map of the galaxies in the sky could shed light on the mysteries of the universe – including dark energy and dark matter.
Einstein’s theory of gravity says dark energy must be out there, accelerating the expansion of our universe. But what is it and how can we try to figure out more about it?
Dark matter’s mysteries are being steadily unravelled by new studies of remote galaxies.
Research of a supernova in our galaxy will increase the precision of which we can measure distances outside of our own galaxy…
A radical discovery by my colleagues and I – reported this week in Physical Review Letters – could help explain why it was possible for life (at least as we know it) to develop on Earth, but not in other…
Some astronomical questions can only be answered by looking at the whole sky all at once but the technology to do that doesn’t exist yet. Enter the new ARC Centre of Excellence for All-sky Astrophysics…
A vital part of professional astronomy is collecting data using large telescopes. In many cases, these telescopes are national or international facilities, with time available to all through a competitive…
