Solar Corona is more Structured, Dynamic than Previously Thought

The SwRI-led team processed solar coronal images to reveal universal gusts, jets and streams (green) emanating from the Sun, offering a possible explanation for the gusty solar wind found around Earth. The upcoming Parker Solar Probe will fly through this riotous torrent as the first spacecraft ever designed to 'touch' the Sun. Credit: Image Courtesy of NASA/SwRI/STEREO

A SWRI-led team discovered never-before-detected, fine-grained structures in the Sun’s outer atmosphere, or corona. The team imaged this critical region in detail using sophisticated software techniques and longer exposures from the COR-2 camera on board NASA’s Solar and Terrestrial Relations Observatory-A (STEREO-A).

The Sun’s outer corona is the source of the solar wind, the stream of charged particles that flow outward fr...
