A Video Clip That Caught My Attention

Title: Northern Lights From Balloon (Project Aether Alaska)
Summary: This Video tells us more about the northern lights, where scientist, teachers and students to observe the Northern Lights or Aurora Borealis they had to launch weather balloons with equipment up to 100,000 feet. 
What I Learnt:

  1. I learnt that the Northern Lights are created when charged particles emitted from the sun during a solar flare and get's deflected by the Earth's magnetic field and collide with the upper atmosphere near the poles.
  2. The charges streaming in from the sun can damage satellites causing extensive power outages and disrupt planes around the poles.
  3. This might lead to a geomagnetic catastrophe.
