ALT The picture shows an area of concern over the LA Basin, foothills and valleys, with a 10-30% chance of a strong thunderstorm forming this afternoon, with brief heavy downpours, small hail, gusty winds and lightning from 2PM to 6 PM.
ALT Description of the difference between graupel and hail. Graupel is soft and wet, hail is hard and solid.
ALT NASA's Viking 1 Orbiter spacecraft photographed this region in the northern latitudes of Mars on July 25, 1976, while searching for a landing site for the Viking 2 Lander. The speckled appearance of the image is due to missing data, called bit errors, caused by problems in transmission of the photographic data from Mars to Earth. Bit errors comprise part of one of the 'eyes' and 'nostrils' on the eroded rock that resembles a human face near the center of the image. Shadows in the rock formation give the illusion of a nose and mouth. The image is in grayscale and shows rocks of different sizes along with small impact craters. dit: NASA/JPL-Caltech

ALT A hill with a V-shaped collapse structure, two craters and a circular fracture pattern — possibly the remains of a buried impact crater — appear to form the face of a bear on the Mars surface.
