The
ultraviolet light of the sun appears to burn electric blue when seen by SOHO.
This image
shows a group of active regions that appear brighter in extreme UV light near the
sun's left edge. The loops on the sun's fringe reflect particles spinning along
and tracing magnetic field lines rising up and above several active regions.
Scientists can observe the slowly changing activity along these magnetic field
lines thanks to SOHO taking images every two and a half
minutes.
The Solar
& Heliospheric Observatory (SOHO) launched as a joint mission between ESA
and NASA in 1995. The spacecraft has the capability to image and examine the
sun from its core to the outer coronal wreath and the solar
wind.
