  • Aurora Borealis from Space: Why Astronauts Can't See the Northern Lights
    The Northern Lights, also known as the Aurora Borealis, are a beautiful display of light in the sky, but you can't see them from space.

    Here's why:

    * Auroras happen in the atmosphere: The Northern Lights are caused by charged particles from the sun interacting with the Earth's atmosphere. This happens in the thermosphere, a layer of the atmosphere about 80-600 kilometers (50-370 miles) above Earth's surface.

    * Space is above the atmosphere: Astronauts orbit Earth above the atmosphere, meaning they are actually above where the aurora occurs.

    So, while astronauts have amazing views of Earth, they wouldn't be able to see the Northern Lights themselves. They might be able to observe the aurora's effects on the Earth's magnetosphere with specialized instruments.
