Explanation:
Dramatic prominences can sometimes be seen looming
just beyond the edge of the sun.
A solar prominence is a cloud of solar gas held
just above the surface by the
Sun's magnetic field.
The Earth would easily fit below the
prominence on the left.
A quiescent prominence
typically lasts about a month, and may erupt in a
Coronal Mass Ejection (CME) expelling hot gas into the
Solar System.
Although very hot, prominences typically
appear dark when viewed against the
Sun,
since they are slightly cooler than the surface.
The above image in false color was taken on June 1 from Stuttgart,
Germany with an amateur telescope and camera.
