BLUE MOON: Tonight's full Moon is the second full Moon this month. According to modern folklore, that makes it a "Blue Moon." Strange but true: Most blue moons look red, pink or gray. On rare occasions, however, the Moon can actually turn blue. A video from NASA explains how.
IONIZATION WAVES: Magnetic fields snaking around the sun's southeastern limb are crackling with C- and M-class solar flares. Extreme UV pulses from the flares are illuminating Earth's upper atmosphere, causing waves of ionization to ripple around the dayside of our planet. Rob Stammes detected the sudden ionospheric disturbances (SIDs) from his laboratory in Lofoton, Norway:
