    unknownskywalker: La Silla Star Trails North and South Fix your camera to a tripod and you can record graceful trails traced by the stars as planet Earth rotates on its axis. If the tripod is set up at ESO’s La Silla Observatory, high in the Atacama desert of Chile, your star trails would look something like this. Spanning about 4 hours on the night of January 24, the image is actually a composite of 250 consecutive 1-minute exposures, looking toward the north. The North Celestial Pole, at the center of the star trail arcs, is just below the horizon in this southern hemisphere perspective. In the foreground, the polished 15-meter diameter dish antenna of the Swedish-ESO Submillimeter Telescope (now decommissioned) shows star trails toward the south by reflection. Sweeping around the South Celestial Pole, the distorted arcs of those stars appear underneath the southern horizon in the focusing dish’s inverted view. Right of the dish is the dome of the observatory’s 3.6 meter telescope, home to the planet hunting HARPS spectrograph.

    unknownskywalker: Self Portrait NASA research pilot Tom Ryan manages a self-portrait while streaking over New Mexico in the ER-2 Earth Resources aircraft on a high-altitude mission carrying the MABEL laser instrument in April 2011. MABEL (Multiple Altimeter Beam Experimental Lidar) will demonstrate the photon-counting altimetry approach to simulate measurements from NASA’s next ice-observing satellite, ICESat-2, scheduled for launch in 2016.
