What is the rarest aurora borealis color?
green
It’s extremely rare to have an aurora without green. Green is the color people usually have in mind when they think of aurora. Above ~250km of altitude, the entities are extremely isolated and scares. The general density of the atmosphere is so low that particles rarely bump into each other anymore.
What happens if you touch the aurora borealis?
The aurora is emitted between 90 and 150 km in altitude (i.e. mostly above the ‘official’ boundary of space, 100 km), so ungloving your hand inside an aurora would likely be fatal (unless a fellow astronaut immediately reattaches your glove and repressurizes your suit).
What causes aurealis borealis?
When the solar wind gets past the magnetic field and travels towards the Earth, it runs into the atmosphere. As the protons and electrons from the solar wind hit the particles in the Earth’s atmosphere, they release energy – and this is what causes the northern lights.

Is the aurora borealis hot?
The northern lights look like fire, but they wouldn’t feel like one. Even though the temperature of the upper atmosphere can reach thousands of degrees Fahrenheit, the heat is based on the average speed of the molecules.
What are Northern Lights caused by?
Auroras occur when charged particles (electrons and protons) collide with gases in Earth’s upper atmosphere. Those collisions produce tiny flashes that fill the sky with colourful light. As billions of flashes occur in sequence, the auroras appear to move or ” dance ” in the sky.
What is a green aurora?
Most solar particles typically collide with our atmosphere at an altitude of around 60 to 150 miles where there are high concentrations of oxygen. When the Oxygen is “excited” at these altitudes it causes the Aurora to appear in shades of green.
