Astronaut Andreas Mogensen was floating 250-miles above the surface of Earth when he captured a mysterious blue light, or what looks like upside-down lightning.
They’re officially called “blue jets,” and its color is believed to be due to a set of blue and near-ultraviolet emission lines from neutral and ionized molecular nitrogen. In addition, whereas red sprites tend to be associated with significant lightning strikes, blue jets do not appear to be directly triggered by lightning (they do, however, appear to relate to strong hail activity in thunderstorms).
