It's now three weeks in space and counting for Butch Wilmore and Suni Williams, as NASA and Boeing troubleshoot problems with their space capsule. Three potential landing dates have so far been called off, and their flight home is now on hold.

Over-zealous aurora chasers in WA's south west damaged a site of historical and cultural importance during May's magnetic storm, now the spot has been removed from a map listing viewing sites.

When Wesley Lamont set up his camera to capture the aurora australis, he had no idea he was trampling on a fragile ecosystem and potentially causing decades of damage.

The Earth has seen its biggest geomagnetic storm in more than 20 years, creating spectacular auroras across the globe. And the Bureau of Meteorology says the southern lights should be visible again tonight. 

Director of the University of Tasmania's Greenhill Observatory Andrew Cole says the previous geomagnetic storm of this strength occurred over 20 years ago.

The Earth has experienced its strongest geomagnetic storm of the past 20 years, resulting in stunning light displays across the globe. But what are geomagnetic storms exactly and do they present a risk to people or the planet?

The aurora borealis and australis — the northern and southern lights — are captured by photographers around the world as a rare solar weather event colours the skies in magical hues.
