Green, Violet, and Gold: Aurora Facts to Drift Away To

The aurora borealis happens when charged particles from the sun travel along Earth's magnetic field lines and collide with atmospheric gases near the poles — causing them to glow. The colours depend on which gas is struck and at what altitude. This session explores the science of auroras slowly and beautifully: the solar physics, the atmospheric chemistry, and the geography of where and when to see them. Perfect for: astronomy and weather fans, nature wonder seekers, calming sleep. #NorthernLightsFacts #AuroraScience #SleepyScience #SpaceWeather #AuroraBorealis
