From their perch, astronauts on the International Space Station have a special vantage of the Earth. Sometimes that view reveals things impossible to observe from the ground.
In late September, astronauts Thomas Pesquet and Andreas Mogensen spotted a glowing blue light over Europe from up in the ISS. They recorded a timelapse and posted a frame of it on Flickr. Pesquet’s caption calls the light a “thunder strike with a ‘transient luminous event’ in the upper atmosphere,” and says this rare occurrence will be further observed by a facility outside Europe’s Columbus laboratory near Munich, Germany.

Spectacular light events in the upper atmosphere are of increasing interest, and astronauts and astronomers have gotten creative naming them. While this particular luminous event hasn’t been named, other unique variations on storms include blue jets, red sprites, and elves. Blue jets are lightning bolts that zap upwards from thunderstorms into the stratosphere. Red SPRITEs (Stratospheric/mesospheric Perturbations Resulting from Intense Thunderstorm Electrification) are brief, soft flashes of color that emanate above an active thunderstorm. The glow can appear in a variety of colors but are usually red and often resemble jellyfish, carrots, or columns. ELVES (Emission of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources) are disk-shaped bursts of light that last just a thousandth of a second. Other fantastically named light phenomena include trolls, gnomes, and pixies.
