Scientists have discovered seven Earth-sized planets packed around a dim star.
The Earth’s magnetic field acts like a giant instrument playing magnetic music.
Hidden Figures is certainly inspirational, but the racial politics of the space programme were hardly so easily settled.
The Outer Space Treaty, now 50 years old, has so far never been violated. But things could be about to change.
As technology advances, tiny satellites no bigger than a loaf of bread have advanced from just proving they work to being big contributors in answering science questions.
Often eclipsed by Apollo 11, the final manned moonshot left far more than bootprints in the dust. In these troubling times, it also left us with a lasting message of hope.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
Listen to some weird space sounds and help identify crunches, whistles and other odd effects. It could help save our satellites.
Using terrestrial forensic science to point the finger of blame to criminals in space will be much harder than it looks.
Leibniz’s ‘great question’ remains a central question in philosophy and science today.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you’ve observed over the years.
Atmospheric changes on exoplanets could hold clues to our own environmental problems.
There’s a disturbing history of solar flares taking out the technology we depend on. As tech becomes more and more vital, knowing what is happening in space is growing ever more crucial.
Whatever happens next in new space race will happen quickly. The opportunity is there for Australia to be involved, but it won’t be there for long.
The rules on armed conflict on Earth are a major source of restraint on military operations. But the rules on the use of weapons in outer space are far from clear. We need to change that.
The latest data from the Dawn space probe points to underground ice flows and a water vapour atmosphere.
Mysterious radiation that appears to come from star HD 164595 is more likely to have a terrestrial origin.
Our growing dependency on satellites for all forms of communication has made the problem of space weather even more acute.
Films set in the ancient world can no longer adequately live up to the demands of the ‘epic’. Instead, we should look to films set in space.
