In five or seven billion years time, the Sun’s life will come to an end. And it will be really spectacular - if you’re watching from far enough away.
Some people think the sky is blue because of sunlight reflected off the ocean and back into the sky. But that’s not the real reason.
The Parker probe will go closer to the sun than any other spacecraft has dared go before – literally touching it.
Energy from the sun’s rays can cause skin damage and cancers. Sunscreens can absorb or reflect the dangerous UV light. Here’s how it works.
Schools need to have a formal policy in place for how to deal with heatwaves effectively and keep children cool and well.
If we survive for another 7.59 billion years, our planet will spiral into the outer layers of the dying sun and melt away forever.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you’ve observed over the years.
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
Our growing dependency on satellites for all forms of communication has made the problem of space weather even more acute.
In the search for life on other planets in the universe we need to find the right kind of star, and it needs to have the right kind of space weather.
The search for new objects, including new planets, in our solar system has turned up some interesting finds. There have been a few failures over the years too.
Alongside the day’s high and low, weather reports generally contain a UV alert for a particular time. But what does it actually mean – and what should you do about it?
Astronauts living on the ISS get to experience the wonders of the universe’s natural phenomena like no one else.
It’s the windiest place in the entire solar system – and these storms can be felt here on Earth.
The recent claim that we might enter a mini ice age in 15 years is not only bad science, but it represents a failure of communication by both scientists and journalists.
Runners have a greater risk of developing skin cancer because they are more likely have sun damage on their skin as a result of chronic sun exposure.
A real-time hand-held device can help employers measure the impact of the sun on workers.
Keytruda® is the latest drug to be registered in Australia for the treatment of widespread melanoma. But we must wait to see if it meets the cost-effectiveness targets for PBS subsidisation.
Summer sunshine makes most of us feel better, but there may be more to the benefits than just feeling good.
