Once there was water….
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
Ain’t half hot: but where’s it heading?
Astrophysicists found out after the January 2014 solar flare that their predictions of solar weather were not very accurate. Here's the fix (kind of).
TshepisoSAT, Africa’s first nano-satellite developed by students and staff at the Cape Peninsula University of Technology.
Nano-satellites are small and cool enough to inspire youth to consider careers in science, technology, engineering and mathematics.
Pale Blue Dot – Earth, imaged by Voyager 1 from 6 billion kilometres away.
From a big blue marble to a tiny dot in space -- reflections on our images of Earth.
Are you afraid of the dark matter?
European Southern Observatory
Every 30 mil years, Earth has to deal with more comet crashes from space and more intense geological activity from within. Dark matter may be the culprit in these episodes that can cause mass extinction.
No Earths were harmed in the making of this image.
The discovery of a thickly viscous layer which traps sinking plates below Earth's surface has wide implications, not least as a cause of earthquakes.
An iconic photo - Earthrise taken by Apollo 8 astronauts in 1968 - reflects how humans must now think of managing the Earth as a whole system.
Rather than impose regulations to limit carbon emissions, policies should focus on innovation and systems change through social sciences.
Artist’s concept of the moon-forming collision.
New experiments show that the asteroids that slammed into Earth and the moon more than 4 billion years ago were vaporised into a mist of iron. The findings, published in Nature Geoscience, suggest that…
Cruithne’s wacky orbit around the sun.
It's the satellite you probably didn't know that Earth has. If we could land on it, it could be pretty useful
Square away your personal philosophy now; proof of life beyond earth is coming.

Astronomers have found thousands of exoplanets and the hunt is on for life beyond Earth. Once biological neighbors are identified, our planet’s philosophies and religions will need to adapt.
Extreme fire is part of life in places like San Diego, USA, pictured earlier this month. But local fire captain Richard Cordova says it’s “very odd for the month of May to have these types of fires”.
Environmentalism is undergoing a radical transformation. New science has shown how long-held notions about trying to “save the planet” and preserve the life we have today no longer apply. Instead, a growing…
