NASA released a video on YouTube of a large solar flare filmed by the Solar Dynamics Observatory satellite.
It’s Friday, December 19 that the satellite Solar Dynamics Observatory (SDO) was film a major eruption on the surface of the sun. It’s Monday that NASA has released this video on his YouTube account.
It was watching this video that we can discover an important activity at the surface of the sun as it s ‘These material projections that measure mostly hundreds of thousands of miles.
Although very pretty and spectacular to watch, this kind of eruptions emits radiation (gamma rays, X, waves radio, etc.) and a cloud of ionized particles that can reach our planet. It was after one to three days they can disrupt communications, GPS and some electronic devices, can also cause magnetic storms capable of damaging the electricity distribution networks. In space, these radiations can make unusable spacecraft, satellites, shuttles, see be dangerous for astronauts.
Visually, these radiations are responsible visible auroras in the sky high altitude, mainly near the Arctic and Antarctic. Precisely on December 22, less than three days after the eruption, a series of images captured.
