A gamma ray burst close to Earth could be devastating.
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.
Enjoy the full moon’s glow.
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.
Truth is out there.
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.
The UV Index was created last century largely for North American and European conditions, which rarely reach the ‘extreme’ range.
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.
Tempestuous times on the solar surface.
It's the windiest place in the entire solar system – and these storms can be felt here on Earth.
A gigantic sunspot almost 130,000 km across captured by NASA’s Solar Dynamic Observatory on October 23, 2014.
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.
Intensive sun exposure for marathon runners in the middle of the day could lead to sunburn, skin cancer and cataracts.
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.
Employers have a duty to keep their employees safe from the sun.
A real-time hand-held device can help employers measure the impact of the sun on workers.
Keytruda® targets a protein on the surface of immune cells that stopped them from attacking the melanoma cells.
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.
Research suggests that sunlight may have benefits that we have not yet discovered.
Summer sunshine makes most of us feel better, but there may be more to the benefits than just feeling good.
Sun exposure that doesn’t result in burning may still damage the skin cells.
Around 30 Australians are diagnosed with melanoma every day and more than 1,200 die from the disease each year. While small amounts of ultraviolet (UV) radiation are required for the production of vitamin…
If you’re at high risk of skin cancer, check your skin regularly.
The earlier you find a cancerous mole, the easier the treatment and the better the outcomes. But it’s not easy distinguishing between harmless, benign moles and those that warrant further attention. In…
GPS is used in many devices to help us navigate.
It’s well known that severe space weather events – which are quite rare – can have a negative impact on our use of Global Positioning System (GPS) enabled devices. But our research, published in Geophysical…
Ten Earths could be laid across the diameter of the gigantic sunspot in AR2191 during its previous rotation – captured on October 23, 2014.
NASA’s Solar Dynamic Observatory
The largest sunspot seen in 24 years is rotating back to face the Earth, and it looks to have grown even bigger. Last month, the solar active region known as AR12192 (also known as AR2192 to some of its…

Each month, at the time of new moon, the sun and moon are together in the daytime sky. Most of the time the moon passes by unnoticed. But at least twice a year, somewhere on Earth will see the moon pass…
Watching the sun over a nature reserve in ACT, Australia.
It’s the time of the equinox or more specifically the spring equinox for us in the southern hemisphere. The equinox is a midpoint. It’s around now that day and night become equal in length (but more about…
