... The ring current (e.g., Frank, 1967) consists of geomagnetically trapped 10 - 200 keV ions (mainly H + , He + , and O + ) and electrons that drift azimuthally around the Earth at radial distances of about 2-7 Re (Earth radii), overlapping the radiation belt region. ... This index can be used to monitor the development of geomagnetic storm (see also geomagnetic activity ), as the main signature (actually definition) of the storm main phase is the build-up of an enhanced ring current. ...

. Astronomers using the European Southern Observatory's Very Large Telescope in Chile have captured this eye-catching image of planetary nebula Abell 33. Created when an aging star blew off its outer layers, this beautiful blue bubble is, by chance, aligned with a foreground star and bears an uncanny resemblance to a diamond engagement ring. This cosmic gem is unusually symmetric, appearing to be almost perfectly circular on the sky. ESO
