Today we hear about the Parkes radio telescope's role in the search for alien life. Our guide is the irrepressible John Sarkissian, the scientist who's had his eye on The Dish since childhood.
NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
A big year ahead for some of the meteor showers this year. Here’s your 2020 guide on when and where to look to catch nature’s fireworks.
On December 26 a solar eclipse will be visible from northern Australia, southern Asia and parts of the Middle East.
Sometimes it is difficult to take a photograph of an exoplanet because the star illuminating it is too bright. Now there is a new ‘deluminator’ telescope that can block out the extra light.
‘The size, the grandeur, the peacefulness of being in the dark’: what it’s like to study space at Siding Spring Observatory

Three hours north-east of Parkes lies a remote astronomical research facility, unpolluted by city lights, where researchers are trying to unlock some of the biggest questions about our Universe.
Many people are still upset that Pluto was demoted from being a planet. But definitions of various celestial objects are fairly fluid. So whether it is an asteroid or moon or planet is up for debate.
There is a massive black hole in the center of the Milky Way galaxy. Measurements of star orbits near this black hole suggest that there may be a second companion black hole nearby.
A determined approach to improving diversity will also lead to better science.
Astronomers using a new technique to hunt black holes found one 70 times as heavy as the Sun
Mysterious cosmic flashes known as gamma-ray bursts are caused by the death throes of massive stars.
There’s really no reason you can’t use binoculars to look into space – and in fact astronomers have been working on doing so for a long time.
Apollo 11 tends to steal the spotlight when it comes to lunar landings. But Apollo 12 was the first mission to make a precise pinpoint landing on the Moon - and without the aid of computers or GPS.
Dark sky sites can inspire new generations of stargazers, but a better long-term solution would be connecting people with the night sky where they live.
Beyond the outer edge of the Solar System, mysterious, unknown worlds await by the thousands. Astronomers can now finally find them and explore them - but will we find another Earth?
Michel Mayor and Didier Queloz thought it would take years to find a planet outside the solar system – they did it in months.
Astronomers have found 20 new moons around Saturn, and will keep finding more as technology improves.
Scientists who discovered planets in far off stellar systems and the fundamentals of the Big Bang Theory have earned the 2019 Nobel Prize in Physics.
A giant exomoon hundreds of times the size of Earth is revealing secrets about how giant planets like Jupiter and Saturn formed. They might also help astronomers find planets where life may thrive.
