Gigantic jets (part of the Transient Luminous Event phenomena) typically form over intense tropic thunderstorms. Current research suggest they are initiated by intra-cloud lightning that triggers a discharge up into the ionosphere.

You can actually see the small blue leader develop above the cloud before it fully discharges as a gigantic jet with vibrant purple and red colors.

After the jet disappears, the leader flickers a few times and surprisingly produces a second jet shortly afterwards. That's something I have not seen before!

This video was recently published by #ESA, but it was extremely dark, so it was hard to see details.
Thanks to the ESA media team who provided me with a higher quality version, I was able to recover lots of shadow details and correct the hotpixel noise.
