APOD: Martian Chiaroscuro (2014 Mar 22) Image Credit: HiRISE, MRO, LPL (U. Arizona), NASA http://apod.nasa.gov/apod/ap140322.html Explanation: Deep shadows create dramatic contrasts between light and dark in this high-resolution close-up of the martian surface. Recorded on January 24 by the HiRISE camera onboard the Mars Reconnaissance Orbiter, the scene spans about 1.5 kilometers across a sand dune field in a southern highlands crater. Captured when the Sun was just 5 degrees above the local horizon, only the dune crests are caught in full sunlight. With the long, cold winter approaching the red planet's southern hemisphere, bright ridges of seasonal frost line the martian dunes. http://hirise.lpl.arizona.edu/ http://mars.jpl.nasa.gov/mro/ http://uahirise.org/ESP_035143_1325 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140322 #APOD

APOD: The View Near a Black Hole (2014 Mar 23) Illustration Credit: April Hobart, CXC, NASA http://apod.nasa.gov/apod/ap140323.html Explanation: In the center of a swirling whirlpool of hot gas is likely a beast that has never been seen directly: a black hole. Studies of the bright light emitted by the swirling gas frequently indicate not only that a black hole is present, but also likely attributes. The gas surrounding GRO J1655-40, for example, has been found to display an unusual flickering at a rate of 450 times a second. Given a previous mass estimate for the central object of seven times the mass of our Sun, the rate of the fast flickering can be explained by a black hole that is rotating very rapidly. What physical mechanisms actually cause the flickering -- and a slower quasi-periodic oscillation (QPO) -- in accretion disks surrounding black holes and neutron stars remains a topic of much research. http://chandra.harvard.edu/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140323 #APOD
