The color of the Aurora depends on the altitude and the atom being struck by solar radiation (causing excitation). At higher altitudes, there is more Atomic Oxygen than Nitrogen, leading to the common color stratifications you see.

500-200 km altitude
— Atomic Oxygen — Red
200-100 km
— Atomic Oxygen — Greenish-Yellow
— Ionized Nitrogen — Blue/Purple
100-80 km
— Nitrogen (N2) — Crimson

Oxygen only emits red at higher altitudes because once it’s excited, it takes a longer time to emit red than it does green. Why is that important? Well, at lower altitudes there is more Nitrogen for the Oxygen to bump into and absorb that excitation-energy before it gets a chance to emit red light. In this case, where the collision occurs, the Oxygen will emit Green and at low enough altitudes the Nitrogen-Oxygen collisions eventually prevent Oxygen from emitting any light at all.

During stronger storms, high energy solar particles will reach lower in the atmosphere and cause the Crimson emission from Nitrogen, creating a deep-red band at the lower edge of the aurora. Other elements emit light too, like Hydrogen (Blue) or Helium (Purple) which are at higher altitudes.

What does this mean?

That, my friend, is exactly the question you have to ask.

YOU LEFT OUT THE MOTHERFUCKING CRYSTAL PYRAMIDS THEY FOUND ON THE FLOOR OF THE BERMUDA TRIANGLE

OLDER THAN THE AZTECS AND COMPLETELY SMOOTH AND 3 TIMES BIGGER THAN THE EGYPTIAN CHEOPS AND NO ONE KNOWS HOW IT GOT THERE.

IM SORRY BUT WHY IS THIS THE FIRST TIME IVE HEARD OF THE CRYSTAL PYRAMIDS WHAT IS THIS SHIT

OKAY HERE’S YOUR DEBRIEFING OF THE CRYSTAL PYRAMID BECAUSE THAT IS SOME CRAZY SHIT.

IN 2012 FRENCH AND AMERICAN SCIENTISTS STUDYING THE BERMUDA TRIANGLE STUMBLED UPON THIS HUGE TRANSLUCENT PYRAMID

THIS THING MEASURED 300 METERS WIDE AND 200 METERS TALL. THAT’S BIGGER THAN THE PYRAMIDS OF GIZA SO YOU COULD IMAGINE HOW CRAZY THIS WAS TO THE SCIENTISTS

NOW THIS IS ALL 2000 METERS UNDERWATER. THE SCIENTISTS THEN DISCOVERED TWO HOLES AT THE TOP OF THE PYRAMID THAT MOVE WATER THRU AT AN EXTREMELY FAST RATE. THIS CAUSES MASIVE SURGE WAVES AND MIST ON THE SURFACE. THAT MAY BE THE REASON FOR THE INCIDENTS WITH BOATS AND PLANES CRASHING THERE

THEY’RE SAYING THAT THIS PYRAMID COULD BE FROM THE TIME BEFORE THE BIBLE SAYS NOAH’S ARK HAPPENED

OR ALIENS

BUT WHATEVER IT IS THE BERMUDA TRIANGLE JUST GOT LIKE A BILLION TIMES CREEPIER

so basically what i’m hearing is that we have found Atlantis

Basically what you found is a fabricated pseudo-science news article that has absolutely no academic source related to it.

Pls google harderer
