Around 15,000 years ago a star 20 times more massive than our Sun dramatically exploded in a region of space within the constellation Cygnus the Swan.
Since then the shockwave and expanding envelope of ejected stellar material and ionised gas has been racing apart, creating a nebulous structure over 130 light years across. This image, captured by Katie Hughes, from her home in Loch Lomond, is all that remains of this event (a supernova remnant) in visible light.
Thank you very much for sharing the stunning image Katie. Katie has recently started an Instagram page with more of her images. Please visit it here.
