We’re a third of the way through the twelve days of Johnny Mackintosh and hitting the meat of the story – far more appetizing than those cold turkey sandwiches you’ve been eating. When my editor suggested “star blaze” to me for a title, this is the image that instantly sprang to mind. For me it simply oozes astonishing power and energy. Even though space is a vacuum that sound wave can’t cross, when I look at this I imagine a deep rumble that hasn’t stopped for five billion years and won’t for another five billion – all being well.

This raging furnace is our Sun. There’s a huge solar flare shooting out from the bottom left-hand corner. The Sun has an eleven year heartbeat, that we don’t understand but which means that the magnetic activity on its surface goes through eleven year cycles. In two to three years we’ll reach a maximum where big flares such as this will be more common, the aurora (the Northern and Southern Lights) will be become more spectacular and visible to more people and there may be times when your mobile phone stops working because of the effect on satellites in orbit. What this picture reminds me of is the incredible power of nature – of the awesome star blaze.

Tomorrow we’re taking several steps further out…
