The Sun sported about a dozen active regions over a five-day period (May 14-18, 2015).
The Sun sported about a dozen active regions over a five-day period (May 14-18, 2015). The bright, spindly strands that extend out of these active regions are particles spinning along magnetic field lines that connect between areas of opposite polarity. These are viewed in the 171 Angstrom wavelength of extreme ultraviolet light, which in this case we have tinted red instead of its usual gold tint. The overall effect is like a graceful ballet of movement. Credit: NASA/SDO
