Our planet is due to be hit with a powerful solar storm, an event that happens about once every hundred years. New research shows that losses from the ensuing blackouts could total $US41.5 billion ($54 billion) per day in the US alone, including nearly $US7 billion ($9 billion) lost in trade.

Like an endless blaze roaring forth from the gates of Hell, the solar wind is majestic, awe inspiring and terrifying. The only proof you need that the Sun is the one and true master of our solar system is this never-before-seen view of a torrent of charged particles bursting out of our star's corona.
Video: It always makes for a beautiful video whenever the suns lashes out with a solar flare. Here's one from earlier this month. You can see how electric its movement are — it just whips up and explodes. The footage was captured in different wavelengths and then colour coded so that we can see what's happening in better detail. In this case, in 4K detail.
Video: Yesterday was the vernal equinox, or the autumnal equinox for those of us in the southern hemisphere. You might think that it's simply the mid-point between each solstice, but that's not exactly correct. Joe Hanson, host of It's OK to be Smart, explains.
It's taken half a century, but we're finally getting a handle on our Sun's complex magnetic field. A new model from NASA captures the strange surface interactions that create dramatic swirls of plasma and corneal mass ejections. If we can better understand the Sun's magnetic field, we might one day be able to predict when it will have an eruption triggering a solar storm.
