If you’re lucky enough to visit the northern regions of Scandinavia or Canada in the winter, you may be in with a chance of observing this magnificent beauty of a cloud…
Once upon a time in a land far, far away, there only existed four basic elements: earth, water, air and fire. The ancient Greeks believed that these four elements constituted everything – in varying amounts and in varying proportions.
The Sun – you might think we’d know quite a lot about this thing already, given how important it is for the sustaining of life on Earth, and well… given just how noticeable it is in the sky. All throughout history, the Sun has represented a cornerstone in mythology, worshipped (and rightly so) by many civilisations. Over the past two weeks we’ve started to scrape away at the surface of what there is to understand about the Sun, but the simple truth is that, despite our everlasting efforts, there’s so much more yet to uncover about this mystical being.
In our last post we took a glimpse at auroras in the making – a spectacular light show staged not by a Roman deity sadly, but by the solar wind. Today we will see where this solar wind originates from (the Sun, unsurprisingly) and see how the draughts of the stars yield the lights of the skies.
