A hint of oxygen and a whiff of methane in a distant exoplanet's atmosphere may be the first evidence we discover of alien life.
Astronomers have built a new observatory in the cold dry air of a high plateau in Antarctica to peer through our atmosphere and observe carbon in our galaxy.
When Kepler was at the very height of his scientific career, his mother was accused of witchcraft.
Climate change is altering the iconic face of Jupiter, too
There's a lot of speculation about a star behaving strangely in our galaxy. But even if it's not evidence of alien intelligence, it's sure to be an amazing discovery.
Citizen science will ensure that the skies have no limit when it comes to research, as ordinary people are encouraged to take part in simple acts of exploration.
The reaction has been swift since a high-profile astronomer's legacy of sexual harassment against his students was exposed.
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.
