Have you ever seen northern lights? Nasa has released a video of the Northern lights seen in the Northern U.S. and in Canada.
Nasa astronomers have taken a breathtaking video of the Northern Lights seen in the Northern U.S and in Canada. The video was taken by the crew of Expedition 30 onboard the International Space Station on January 29, 2012 from 10:18:13 to 10:31:28 GMT.
In the video, we can clearly see the images of the light from the electric glow of hundreds of cities to a spectacular aurora borealis flickering on the northern horizon. The video begins as the space station is passing over the dark waters of the North Pacific Ocean northeast towards Vancouver Island. The Aurora Borealis can be seen far north, where both the underside and top of the aurora are visible.
Northern lights is also known Aurora Borealis, it is usually seen in the Northern Hemisphere. Aurora Borealis is formed when a "solar wind" of charged particles from the Sun enters the Earth's magnetic field, accelerating electrically charged particles trapped within. The high-speed particles then crash into Earth's upper atmosphere over the Polar Regions thereby causing the atmosphere to emit a natural multicoloured glow.
