Red Sprite

The European Space Agency (ESA) astronaut captures images of red sprite from ISS Cupola observatory.

It is dubbed as red lightening which lasts merely a millisecond.
It is a part of transient luminous event (TLE), a rare electrical discharge that can appear over thunder clouds.

Unlike typical lightning bolts that descend from the clouds to the ground, a sprite behaves inversely, ascending into the atmosphere, resembling a form of reverse lightning.

Location – It forms between 40 and 80 kilometers above Earth and is rarely visible from Earth.
Thor-Davis ISS experiment – It aims to investigate upper atmospheric lightning and its implications on greenhouse gas levels, thereby influencing global warming.
It will photograph storms from the vantage point of the International Space Station's (ISS) observatory.
Davis Camera – It works like the retina in our eyes that is sensitive to changes in light, allowing it to take up to the equivalent of 100.000 pictures per second.
