Astronomers have discovered huge active plumes containing water vapour being released from the surface of Jupiter's moon Europa.  Jupiter's moon Europa has been a focus of extraterrestrial…

This is an interesting question I was asked recently on the space show. It's inspired by this 5 note theme from the 1970s movie. (if you don't see videos in this page, try reloading it). It's…

Whether human beings and extraterrestrials could communicate with each other using music. This is a question I was asked on the space show. It was inspired by the 1970s movie with this theme tune: 5…

Over a year after being launched, NASA's Van Allen Probes mission continues to unravel the mysteries of Earth's high-energy radiation belts that encircle our planet and pose hazards to orbiting…

Astronomers have identified the glowing wreck of a star that exploded a mere 2,500 years ago — the blink of an eye in astronomical terms - and revealed an astrophysical novelty of the Milky Way…

A model has shown that the subsurface ocean on Jupiter's moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life. Astronomers…

Separate teams of scientists have found faint signatures of water in the atmospheres of five distant planets, the first study to conclusively measure and compare the profiles and intensities of…

In boxing a devastating puncher has heavy hands. On a cosmic scale, the high-speed 'jets' spat out by black holes pack a lot of power because they contain heavy atoms, astronomers have found. Black-…

Our Galaxy may have been swallowing "pills" — clouds of gas with a magnetic wrapper — to keep making stars for the past eight billion years, according to CSIRO astronomer Dr. Alex Hill and colleagues…

A few months ago astronomers created a new 3-D map of stars at the center of our Galaxy which cleared showed the bulge at its core. Previous explanations suggested that the stars that form the bulge…
