Racetrack sailing stone and star trails. A sliding rock of the Racetrack Playa. The sliding rocks, or sailing stones, move across the mud flats of the Racetrack Playa, leaving trails behind in the mud. The explanation for their movement is not known with certainty, but many believe wind pushes the rocks over wet and perhaps icy mud in winter.

Milky Way during Full Lunar Eclipse over Arch Rock, Joshua Tree National Park, April 4 2015. The arch and surrounding landscape are illuminated by the faint light of the fully-eclipsed blood red moon. Light from the sun has passed obliquely through the Earth's thin atmosphere, taking on a red color, and is then reflected off the moon and reaches the Earth again to light the arch. The intensity of this light is so faint that the Milky Way can be seen clearly at the same time.
