The Australian Square Kilometre Array Pathfinder uses several telescopes to survey the sky.
After months of running in test-mode, the Australian Square Kilometre Array Pathfinder telescope is now gathering data at an incredible rate to give us a new look at how our universe works.

A new book explores some of the big questions of why the universe exists and why it seems fine-tuned for life.
Leibniz’s 'great question' remains a central question in philosophy and science today.
The expanding universe.
New research out this month has led to speculation that the acceleration of the expanding universe might not be real after all. So what's really going on?
Truth is out there.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
Light from the universe’s first galaxies destroyed the hydrogen atoms that formed during the Big Bang.

A new telescope aims to figure out what became of the universe's original atoms once the first stars began to shine.
A small section from the ZFOURGE survey, which contains thousands of galaxies spanning billions of years.
Hundreds of images of thousands of galaxies have given astronomers one of the most detailed galaxy studies ever compiled.
An illustration showing the merger of two black holes and the gravitational waves that ripple outward.
The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.

Astronomers think they may have found evidence within our galaxy of some of the missing matter thought to make up our universe.
Like a cosmic roulette wheel, we exist because of a very lucky combination of factors.
If some of the laws of physics were only infinitesimally different, we would simply not exist. It almost looks like the universe itself was built for life. But how can that be?
A colour image of G63349, one of the galaxies in the survey, created using near-infrared (VISTA telescope) and optical (Sloan telescope) data collated by the GAMA survey. (The bright green object is a nearby star.)
Our universe's most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.
What secrets will space reveal?
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
The atmosphere of black holes contain a matter-antimatter plasma.
An exotic plasma could help shed light on why the universe as we know it is made up of more matter than antimatter.
Wide-eyes: the Square Kilometre Array in the Karoo in South Africa.
The Square Kilometre Array is the world's largest telescope – what will it do and how does it work?
The Hubble Space Telescope hovers at the boundary of Earth and space.
Twenty-five years on and the Hubble Space Telescope is still taking some amazing images. But there have been a few glitches over the years, right from day one.
Elliptical galaxies, like this one, are burnt out and no longer making stars.

What happens to a galaxy when it runs out of the stuff needed to forge new stars?
Looking for dark matter in the galaxy collisions such as in Abell 2744, dubbed Pandora’s Cluster.

Scientists know so much about dark matter apart from what it is exactly. But are they getting any closer?
Some of the antennas of the Murchison Widefield Array radio telescope, designed to uncover what happened in the first billion years of the universe.
More than 100 million years has been wiped off the age of the first stars but there is still the question of what happened in the first billion years of the universe. Earlier this month the European Space…
Spot the biggest.
The universe is such a big place that it is easy to get baffled by the measurements that astronomers make. The size of UY Scuti, possibly one of the largest stars we have observed to date, is certainly…
New data reveals no evidence of gravitational waves in the early universe, as observed by the BICEP2 radio telescope (pictured) near the South Pole.

One of this century’s greatest potential discoveries concerning the origins of the universe has now fallen to galactic dust. That’s according to a new joint-analysis of all the existing data – including…
