A flash of light, a burst of energy: In a rare video captured by NASA, a solar flare is caught on camera. The flare peaked on Tuesday, creating a massive cloud that covered almost half the sun, NASA said. Solar flares are caused by a build up of magnetic energy, released into the solar atmosphere. The amount of energy is equivalent to millions of hydrogen bombs exploding at the same time.
Though the energy released is not heading directly at the Earth, it may cause some atmospheric disturbance on Wednesday or Thursday night, enough to cause some spectacular auroras and possibly disrupt some satellites, NASA reports .
