- The northern lights, one of several astronomical phenomena, are shafts or curtains of colored light visible on occasion in the night sky.
- you have a lot to learn. plus we have to explain how they work for our science project.
- How does that work
- The Northern Lights are caused by the interaction of the solar wind - a stream of charged particles escaping the Sun - and our planet's magnetic field and atmosphere
- then, as these charged particles "excite" gases in our atmosphere, they make make them glow
- The solar wind can cause the Earth's magnetic field lines to disconnect from our planet. When these field lines "snap back" into position, charged particles from the solar wind are again pushed into the Earth's atmosphere, causing aurora.
- wow. that's so cool
