About 5 percent of all UFO sightings cannot be easily explained by weather or human technology. A physicist argues that there's compelling evidence to justify serious scientific study and that the skeptics should step aside – for the sake of humanity.
An asteroid on a collision course with Earth is inevitable. Astronomer Michael Lund explains how a new telescope under construction in Chile will become a vital tool for detecting objects that could devastate our planet.
35 years ago Sally Ride became the first American woman in space. But rather than focus on her own extraordinary achievements, her passion became boosting the number of girls pursuing STEM. Another pioneering astronaut remembers her friend and colleague.
Australia occupies a unique location vital for supporting NASA and ESA deep-space missions.
Following NASA's latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
Now's a great time to see Jupiter as it's about to be the closest to Earth for some time. Time too to catch up with the latest on the Juno mission, exploring the largest planet in our Solar System.
The little-known Rossi X-ray Timing Explorer spacecraft was like a Geiger counter for the universe, listening to black holes and zombie stars.
What is Mars made of? We hear from a scientist who will be part of the team analysing 'marsquake' seismic data and orbital imagery from the InSight mission to the red planet.
The new planet-hunting telescope TESS was successfully launched today by NASA, and Australia will play a key role in checking out any new worlds it discovers.
How long before we find a planet just like our own?
When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase.
It's been reported that astronaut Scott Kelly no longer has the same DNA as his twin brother after spending a year in space.
Surprising new results from the Juno mission may us help work out what's going on at Saturn and other gas giants, too.
Google's artificial intelligence has been taught to look for planets around other stars. It's already making new discoveries that scientists have missed.
A new trajectory means the mission to uncover core facts about the asteroid belt will happen sooner than planned.
Dreams of new footprints on the moon are more about domestic politics than foreign policy.
The discovery of tiny ripples in space from the violent collision of dense stars could help solve many mysteries – including where the gold in our jewellery comes from.
Future Mars colonists may want to form their own legal system. What would stop them?
