Tanya Hill speaks with Meg Urry about distant galaxies and the supermassive black holes that lurk in their centres.
NASA has set a target date of 2030 for a manned mission to Mars. With no real scientific breakthroughs needed, success depends on developing the proper technology.
A rare super blood moon visible from parts of the Earth this month will delight those people lucky enough to see it. But why has this marvel of the solar system got some people so worried?
Plans to build a new telescope on a Hawaiian mountain highlight the complexities and sensitivities that arise when science interacts with indigenous communities.
Geomagnetic storms can interact with particles near Earth, causing issues for satellites and other tech. Researchers send balloons 20 miles into the sky to figure out just what's going on up there.
When government funding is cut from science and research in Australia, there are other ways to try to draw money from the public's purse?
They're are the overachievers of the universe: incredibly dense but very small when compared to others stars. So how much do we know about the extreme behaviour of neutron stars?
The next decade will be an exciting one for Australian astronomy, as we probe the heavens for answers to age old questions.
HD 219134 b may not be a catchy name - but our new planetary neighbour deserves just as much attention as Earth's cousin, Kepler-452 b.
Kepler-452b's discovery last week has raised the perennial question: are we alone in the universe? While the find's scientific import is huge, it also poses questions that go to the heart of religion.
Given Earth is our sole example of life in the universe, it's hard to know what we're looking for elsewhere in the cosmos.
In the long lead-up to our ultimate flyby of Pluto, space science has reconfigured our notions of what it means to be a solar system, a planet, a world.
Astronomers can tell a whole lot more about a star or a galaxy if they break up the visible light in a rainbow of colours.
The existence of a "Planet X" in the outer solar system was the subject of great speculation, and was finally settled with the discovery of Pluto in 1930.
From Twinkle Twinkle to Space Odyssey and beyond, humans have always turned to music to help deal with the profoundly confronting enormity of the cosmos. Is that a match made in the heavens?
The moon might harbor bits of the Earth that blasted off our planet billions of years ago. These lunar time capsules could hold secrets about conditions here at home back when life was first emerging.
Look up tonight and you'll see a stunning conjunction of the two brightest planets in the night sky.
A unique map of the galaxies in the sky could shed light on the mysteries of the universe – including dark energy and dark matter.
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
Astronomers have spotted the earliest known stars in the universe, belonging to a class of chemically pure stars that may never have been seen before.
