Tangled up in blue ☀️?
.
The lone active region visible on the Sun on April 24-26 put on a fine display, with tangled magnetic field lines swaying and twisting above it.
.
Active regions are areas of intense and complex magnetic fields on the Sun that are often associated with solar eruptions, though this region has not erupted with any significant solar storms while on the Earth-facing side of the Sun.
.
Seen in extreme ultraviolet light by NASA's Solar Dynamics Observatory, the magnetic field lines above the active region are traced out by the charged particles spinning along them. Extreme ultraviolet light is typically invisible to our eyes but is colorized here in teal.
