An artist’s impression shows the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to our solar system.
Astronomers have found an Earth-like planet orbiting our nearest neighbour, the red dwarf star Proxima Centauri. So any chance that planet may be habitable?
Artist’s impression of the surface of the planet Proxima b, orbiting Proxima Centauri.
Scientists have finally found an Earth-like planet we may actually be able to visit.
Specialized chamber to study dusty plasma in the lab.
The vast majority of matter in the universe is plasma: electrically charged gas. Scientists are untangling how dust interacts with plasma both in space and experimentally closer to home.
The annual Perseid meteor shower gives us a glimpse of remnants from the early formation of the solar system.
We can all reach for the stars in The Milky Way over Western Australia.
The drive the get more women involved in science should start at an early age. But as one space researcher found out, girls can get nudged out of science at school.
The FAST telescope.
The Aperture Spherical Radio Telescope could help reveal how the universe evolved.
The 500-metre Aperture Spherical Telescope (FAST) is the largest single-dish radio telescope in the world.
You can't just buy a radio telescope receiver off the shelf. So CSIRO has been hard at work building receivers for the world's largest telescopes using the very latest technology.
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.
An artists’s impression of how common planets are around the stars in the Milky Way.
A look at some of the more obscure methods astronomers use to detect planets around other stars, in the second of a two-part series on finding world's elsewhere in the universe.
The new discovery: The C-shaped “wide angle tail galaxy” (pink) surrounded by the galaxies of the Matorny-Terentev cluster (white).
The find by citizen scientists of at least 40 galaxies in a cluster more than a billion light years away is the astronomical equivalent of finding a needle in a haystack.
In the Exoplanet Era, we are learning that planets abound in the cosmos.
Astronomers have discovered more than 3,000 planets around other stars, so far. In the first of a two-part series we look at how they find world's elsewhere in the universe.
There are two broad ways to measure the expansion of the universe. One is based on the cosmic microwave background, shown here, along with our own galaxy viewed in microwave wavelengths.

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.
Artist’s rendition of one of the billions of rocky exoplanets in our galaxy.
Did life once exist on its surface?
Complex life may be rare in the universe because most planets become either too hot or too cold before life has a chance to get a foothold. This might explain why we have yet to bump into E.T.

Something mysterious is pulling our Milky Way through space at a much faster rate than expected. So what could it be?
Galileo’s sketches of the moon, showing its phases.
We take our understanding of the solar system for granted, but it took centuries to figure out. The original writings of Ptolemy, Copernicus, Galileo and others show how they sparked a revolution.
An artist’s impression of a transiting Jupiter-mass exoplanet around a star slightly more massive than the sun.
Many of the new planets found in other star systems have some extraordinary orbital behavior. So what's going on?
Windy black hole.
It was a rare and brief event, but powerful telescopes helped scientists get a glimpse of a black hole letting out a wind at 3,000km per second.
ESA’s Swarm constellation reveals new rapid changes of our magnetic field, tied directly to the heart of our planet’s molten iron core.
Space research never stops and it seems neither do the surprises. On ABC Breakfast News I covered some huge results from the last few weeks. Be still my beating (magnetic) heart Earth’s magnetic field…
Those tiny streaks sometimes land, and they can tell us a lot about the sky.
Hunting for meteorites in the vast Pilbara is hard work, but even a tiny speck can tell us a great deal about the sky billions of years ago.
An artist’s concept of select planetary discoveries made to date by NASA’s Kepler space telescope.
The number of known exoplanets doubled this week to more than 3,200. But why have only a handful of these those new planets caught people's imagination?
