Big solar blowouts hold clue to space weather

more »

Solar jets are ejections from the surface of the Sun, where 1-10 tons of hot material are expelled at speeds of up to 1000 kilometers per second. Using space based observatories like Hinode and STEREO, solar physicists have recently discovered a new type of jet known as ‘blowout’ jets, which seem to be like the Coronal Mass Ejections (CMEs) that can disrupt the magnetic field of the Earth, but on a much smaller scale. Now a scientist has created a 3-D model of these events for the first time, with compelling computer-generated simulations that match the jets’ appearance from space.
