Stunning footage shows the Northern Lights bursting with colour over Lapland as scientists reveal the spectacular light show is MORE colourful because of a change in the sun's atmosphere
Scientists say the spectacular light show was bursting with more colour this week because of a huge hole that has opened up in the sun's corona. The northern and southern lights, also known as the 'Auroras', are triggered when electrically-charged particles from the sun enter the Earth’s atmosphere. Solar flares only impact Earth when they occur on the side of the sun facing the Earth. Sometimes, these explosions can send out coronal mass ejections - large clouds of plasma and magnetic field that erupt from the sun. The increased number of charged-particles ejected from the hole in the sun's upper atmosphere combined with a potent burst of solar wind is believed to have fuelled more intense light shows. These have also extended the reach of the 'Aurora Borealis', or Northern Lights, which can now been seen at high latitudes in the US and UK. Posted by: Skidmark 2018-09-14 |
