AI Summary
5 min readThe Earth’s atmosphere, far from being empty, is a dynamic theater of electrical and fluid activity. In recent years, highly sensitive cameras have documented a series of previously unrecorded light-producing phenomena high in the sky, known collectively as transient luminous events (TLEs). These include red sprites, blue jets, gigantic jets, and elves—each a distinct, short-lived electrical discharge that occurs above thunderstorm systems. At the same time, amateur photographers and citizen scientists have helped identify entirely new cloud types, such as asperitas clouds, and researchers continue to study noctilucent clouds, which form at the edge of space. Together, these phenomena reveal that the atmosphere is far more active, strange, and interconnected than was once believed.

What you'll learn
- 1 (01:06) **Introduction to Transient Luminous Events (TLEs)** - Overview of rare, high-altitude light phenomena in Earth's atmosphere, setting up the mystery of what they are and why they're so elusive.
- 2 (02:23) **Red Sprites: Cold Plasma Jellyfish** - Description of red sprites, massive cold plasma events that can span 50 km and travel at 10% the speed of light.
- 3 (05:56) **Blue Jets and Gigantic Jets** - Distinct TLEs initiated by storm systems, producing cone-shaped jets that glow blue due to lower altitude and higher pressure.
- 4 (07:12) **Elves: The Rarest and Least Understood TLE** - Diffuse, ring-shaped phenomena that can grow up to 400 km in diameter but last only a millisecond, caused by an electromagnetic pulse from a thunderstorm.
- 5 (08:45) **Introduction to Asperitas Clouds** - A rare cloud type recognized by the WMO in 2017, described as looking like a stormy ocean flipped upside down.
- 6 (11:16) **The Discovery of Asperitas Clouds** - The story of amateur photographer Jane Wiggins' 2006 photo, which sparked a crowdsourced effort leading to official recognition.
- 7 (13:57) **What Makes Asperitas Clouds Unique** - Explanation of cloud classification and how asperitas clouds are defined by their rough, chaotic wave-like base, unlike the smooth undulatus type.
