A magnitude 3.9 earthquake occurred in the NSW Southern Highlands on Thursday morning, causing the ground to shake as far away as Orange and Canberra. So, how common are earthquakes in Australia and how did this one compare to our country’s largest recorded earthquakes? The ‘quake that shook NSW on Thursday morning had an epicentre […]
All manner of anti-shark devices claim to keep the apex predator away from humans, yet several marine ecologists say some hammerheads need protection from us. Scalloped hammerhead sharks (Sphyrna lewini), named for the notches along their distinct head, are critically endangered. Despite their ongoing global decline, we don’t know much about them. But in recent years, schools of the marine creatures have […]
There will be clear skies in eastern areas but swathes of thick cloud will cover the west. Wind speeds are forecast to reach more than 8000km/h. And pack your sunscreen, as it will be hot enough in the sunshine to forge iron. NASA has used the James Webb Space Telescope to produce one of the […]
Astronomers have discovered the oldest supermassive black hole yet – almost dating back to the time of the Big Bang. The black hole, which is an estimated 10 to 100 million times more massive than our sun, is 13.2 billion light-years away in the galaxy UHZ-1. This means its light has travelled 13.2 billion years to […]
New York: “Just keep telling the story”, says the director character in Wes Anderson’s latest film, Asteroid City, which takes a stylised look at mid-century America’s fascination with space and interstellar communications. Later this year, the Lunar Codex – a vast multimedia archive telling a story of the world’s people through creative arts – will start heading […]
NASA’s nearly 33-year-old observatory still has plenty of top science to do, and astronomers want to extend its lifetime. Once the James Webb Space Telescope (JWST) began operations last year, the comparisons began. Astronomers and others online posted side-by-side images of the same celestial objects captured by JWST and the Hubble Space Telescope, pointing out how […]
