Eruptive events on the Sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material (called a coronal mass ejection – CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the Sun’s atmosphere, the corona. On July 19, 2012, an eruption occurred on the sun that produced all three. Watch the video…

A long filament of solar material that had been hovering in the Sun‘s atmosphere, the corona, erupted out into space. The coronal mass ejection, or CME, traveled at over 900 miles per second, held on August 31, 2012 at 4:36 p.m. EDT. Watch the video

During this total solar eclipse in 2008, the solar corona can be seen with naked eye.

Cloud iridescence is a fairly uncommon phenomenon and is usually observed in altocumulus, cirrocumulus clouds, most frequently seen near to the sun when small ice crystals in clouds individually scatter light.

The Sun’s corona is threaded with a complex network of magnetic fields, and this amazing new image from the Solar Dynamics Observatory shows the magnetic field lines associated with a coronal hole that is now turning to face Earth.
