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.
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.
Forget your troubles for a moment and look at the sky.
The night sky, I mean.
Sadly in an urban metropolis such as the one I live in there isn’t much to see at night besides the faint glow of a near Full Moon. A telescope, however, paints on the black canvas of the night sky and unlocks an entirely new world.
