“Transient luminous event” sounds like a euphemism for a ghost, but it’s actually a beautiful phenomenon that can sometimes be seen from the International Space Station. European Space Agency astronaut and current ISS resident Thomas Pesquet shared a view of an ethereal blue glow emerging over Europe. CNET reports: Transient luminous events are caused by upper-atmospheric lightning. This one happened in early September and Pesquet tweeted about it this week, calling it “a very rare occurrence.” “What is fascinating about this lightning is that just a few decades ago they had been observed anecdotally by pilots and scientists were not convinced they actually existed,” Pesquet said on Flickr. “Fast forward a few years and we can confirm elves, and sprites are very real and could be influencing our climate too!” Pesquet’s image represents a single frame from a time-lapse taken from the station. The image would be a beauty just for the way it shows the curve of Earth and the twinkling lights of Europe below. The transient luminous event captured at its finest moment takes it to the next level.
