A red sprite:


Upper-atmosphere lightning, also called trasient luminous discharge, includes red sprites, which appear above the cloud level in the stratospshere - often 50 - 90 miles above the ground - and are caused by the positive discharge of cloud-to-ground lightning. They often feature branches above or "tendrils" hanging down toward the clouds.

Blue jets erupt from the top of a cumulonimbus into the ionosphere, are rarer than sprites, and don't seem to be connected with traditional lightning though they may be associated with hail.

ELVES (a dummy acronym for Emissions of Light and Very low frequency perturbations from Electromagnetic pulse Sources) are short-lived (~ 1 millisecond) flattened discs of glow which are believed to be caused by the excitation of nitrogen molecules stemming from lightning discharge.

The scale of the universe

That is really cool.

Aye, that's a very good one.

Thanks. I have to figure out how to work 'yoctometer' into a fic.

Technobabble away my friend.

But it must make sense in the context of the story and narrative, Sionnach.

Or something along those lines.

How about a different context?

"I'm not even getting a blip on the yoctometer, sir."

... I just realized. I do have a fic idea where this can work. Thank you, Tsuki!

Hey, I'm useful for once!

True to their ominous appearance, mammatus clouds are often harbingers of a coming storm or other extreme weather system. Typically composed primarily of ice, they can extend for hundreds of miles in each direction and individual formations can remain visibly static for ten to fifteen minutes at a time. While they may appear foreboding they are merely the messengers - appearing around, before or even after severe weather.

Well, that kicks ass.
