Sky Oddities • Sub-Hub 4 • Plasma Phenomena
Auroras & Plasma Phenomena explores the glowing, electric and magnetically driven sky events that make Earth’s upper atmosphere look temporarily hacked by the Sun, thunderstorms and invisible electromagnetic forces.
This sub-hub covers luminous phenomena created by Earth’s magnetosphere, charged particles, plasma, atmospheric electricity and upper-atmosphere electromagnetic interactions — from auroras and STEVE to red sprites, blue jets, ELVES and mysterious atmospheric glows.
TL;DR: What This Sub-Hub Covers
- Auroras — glowing polar and low-latitude displays caused by charged particles interacting with Earth’s atmosphere.
- STEVE and SAR arcs — strange subauroral light phenomena linked to ionospheric and geomagnetic activity.
- Sprites, blue jets and ELVES — upper-atmosphere flashes triggered above powerful thunderstorms.
- Atmospheric plasma and luminous phenomena — rare glowing events, plasma-like observations and unexplained atmospheric lights.
What Are Auroras & Plasma Phenomena?
Auroras and plasma phenomena are luminous sky events produced when charged particles, magnetic fields, ionized gases, lightning systems or atmospheric electrical processes interact with Earth’s atmosphere.
Some are driven by Earth’s magnetic connection to the Sun. Others are triggered by thunderstorms or upper-atmosphere electrical discharges. Together, they form one of the strangest branches of sky oddities: glowing curtains, purple arcs, red flashes, blue columns, expanding rings and mysterious atmospheric light events.
Auroras Explained
Auroras are glowing displays produced when charged particles enter Earth’s upper atmosphere and excite oxygen and nitrogen. They include both the northern lights and southern lights, as well as rare low-latitude and extreme aurora events.

STEVE & Subauroral Phenomena Explained
STEVE is a narrow purple-white arc seen outside the usual auroral oval. Unlike normal auroras, STEVE is linked to fast subauroral ion flows and unusual ionospheric conditions. Related red arcs and subauroral glows reveal how strange Earth’s near-space environment can become.

Sprites, Blue Jets & ELVES Explained
Sprites, blue jets and ELVES are transient luminous events that occur high above thunderstorms. They are brief, strange and spectacular: red jellyfish-like flashes, blue upward jets and huge expanding rings of light near the edge of space.

Atmospheric Electricity & Plasma Phenomena Explained
Some glowing sky events are linked to atmospheric electricity, ionized air, rare plasma-like observations and poorly understood luminous atmospheric phenomena. This pillar acts as the 301 sink for strange glowing sky events that do not belong cleanly under auroras, STEVE or thunderstorm-driven upper-atmosphere flashes.

What This Sub-Hub Does Not Cover
This sub-hub focuses on luminous atmospheric and near-space phenomena as seen in the sky. It does not serve as the main home for solar physics or space weather topics.
- Solar cycles
- Solar flares
- Coronal mass ejections
- Space weather forecasting
- Solar physics
Those topics belong in the Space & Beyond cluster, especially the dedicated Space Weather section.
Related but separate: Ball Lightning Explained belongs in the Lightning Phenomena silo and should be linked here, not duplicated.
Why These Phenomena Matter
Auroras and plasma phenomena are not just beautiful lights. They reveal how Earth interacts with charged particles, magnetic fields, thunderstorms and the upper atmosphere. Some are well understood. Others remain rare, difficult to observe and scientifically fascinating — exactly the kind of sky weirdness Strange Sounds was built for.
FAQ: Auroras & Plasma Phenomena
Are auroras plasma phenomena?
Yes. Auroras involve charged particles and ionized atmospheric gases glowing in Earth’s upper atmosphere.
Is STEVE the same as an aurora?
No. STEVE looks aurora-like, but it is linked to different subauroral processes and fast ionospheric flows.
Are sprites and blue jets caused by auroras?
No. Sprites, blue jets and ELVES are triggered by thunderstorms, not by auroras.
Where should solar storms be covered?
Solar storms, solar flares, CMEs and space weather forecasting should be covered in the Space Weather cluster, not in this sub-hub.
