But not many people know that the other gas giants in our Solar System – Jupiter, Uranus and Neptune – also have rings, although they’re much fainter than those of Saturn.
One of the most enduring mysteries of astronomy and space science is something that’s come to be universally known as the ‘Wow! signal’.
Australia woke to news this morning that NASA’s latest spacecraft launch from Florida’s Kennedy Space Center was a huge success. Our own Karina Holden was there for lift off!
After a stellar 50 years as one of the country’s major scientific assets, the Anglo-Australian Telescope continues to play a major role in keeping Australian astronomy on the world stage.
On October 10, NASA is launching a new mission to find habitable spots on Jupiter’s fourth-largest moon, Europa.
Earth is getting a tiny new mini-moon for a few weeks. It won’t be the first – or the last.
Comets and meteorites aren’t just space rocks; they’re a window into the history of Earth and have plenty to teach about the planet’s formation.
