... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

. This graphic plots the source locations of the geysers scientists have located on Enceladus' south polar terrain. The 36 most active geyser, or jet, sources are marked by circles and color coded by the behavior of the grains erupting from the geysers. Other, less active sources are marked by small black squares.
