Solar physicist Steven Cranmer of the University of Colorado Boulder, who has made simulations of magnetic reconnection in the outer corona, finds the results exciting.

DeForest and colleagues collected data for three days with STEREO in 2014 to gain more detail about small - scale changes in the outer corona than previously obtained.

Surprisingly, the team found that the outer corona is full of moving blobs and fine streams of plasma that vary in density by a factor of 10, suggesting that the magnetic field lines there are moving and merging more than scientists thought.

But in the best observations until now, the outer corona appeared smooth and uniform.

Newly analyzed observations from NASA's STEREO spacecraft show that the sun's outer corona is just as complicated as the highly structured inner corona, solar physicists reported December 12 at the fall meeting of the American Geophysical Union.

This image from the Interface Region Imaging Spectrograph (IRIS) shows emission from hot plasma (T ~ 80,000 - 100,000 K) in the Sun's transition region — the atmospheric layer between the surface and the outer corona.

Vibrant brown and orange — just like a mid-decade knit polyester shirt — these solar portraits snapped from Skylab, the first U.S. manned observatory, allowed the outer corona of the sun to be seen clearly for the first time.

«We've tracked sound - like waves through the outer corona and used these to map the atmosphere,» said Craig DeForest of the Southwest Research Institute in Boulder, Colorado.

Using a disk called an occulter to block out the sun's brightness, space telescopes like NASA's Solar and Heliospheric Observatory watch the outer corona all the time.
