Do you wonder why you didn't see the Northern Lights with your eyes like all of the photos being posted? Letโs talk about the Aurora Borealis in general for a moment. Aurora Borealis are caused by electrons colliding with the upper reaches of Earth's atmosphere. This creates an energy release in the form of light. In best-case scenarios for onlookers, splashes of red/pink, green, yellow, blue and violet fill the night sky. Those color tones can vary moment by moment and based on conditions. Only in the most powerful energy storms can these be visible to the naked eye. People ask all the time why they cannot see the lights when photos are posted showing the beautiful heavens. The simple answer is that human eyes can't see the relatively faint colors of the aurora at night. ๐๐๐บ๐ฎ๐ป ๐ฒ๐๐ฒ๐ ๐ต๐ฎ๐๐ฒ ๐ฐ๐ผ๐ป๐ฒ๐ ๐ฎ๐ป๐ฑ ๐ฟ๐ผ๐ฑ๐ โ the cones work during the day and the rods work at night. Cone cells are high-resolution and detect color in bright light. These are the main cells we use for vision in the daytime. Rod cells can detect much fainter light at night, but only see in black and white and shades of gray. The Northern Lights only appear to us in shades milky of gray because the light is too faint to be sensed by our color-detecting cone cells. Camera sensors don't have that limitation. Couple that fact with long exposure times and high ISO settings of modern cameras and it becomes clear that the camera sensor has a much higher dynamic range of vision in the dark than people do.
Hopefully, that answers some of your questions!
