Two active regions with their intense magnetic fields produced towering arches and spiraling coils of solar loops above them (June 29 - July 1, 2014) as they rotated into view. When viewed in extreme ultraviolet light, magnetic field lines are revealed by charged particles that travel along them.

A coronal hole, almost square in its shape, is one of the most noticeable features on the Sun of late (May 5-7, 2014). A coronal hole is an area where high-speed solar wind streams into space. It appears dark�in extreme ultraviolet light�as there is less material to emit in these wavelengths.

NASA’s Solar Dynamics Observatory (Little SDO) creates composite images, like the lead image, the show a series of eruptions in color-indiciative imagery to make visible the differences in wavelengths. Others in the collection make visible differences in intensity, radiation levels, temperature. All of them are beautiful.
