Spacecraft Witness 'Puffing' Sun Causing a Reluctant Eruption

Science World Report

Astronomers have spotted an unusual series of eruptions form the sun, thanks to a suite of spacecraft. The outermost layer of the sun is called the corona. The big, slow structure is reluctant to erupt, and does not begin to smoothly propagate outwards until several jets have occurred. Currently, the scientists plan to further investigate this event in order to find out whether there are shock waves, formed by the jets, passing through and driving the slow eruption, or whether magnetic reconfiguration is driving the jets, allowing the structure to slowly erupt. The findings could tell scientists a bit more about the sun and the forces that drive it.
