APOD: Saturn Hurricane (2013 May 02) Image Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA http://apod.nasa.gov/apod/ap130502.html Explanation: Acquiring its first sunlit views of far northern Saturn late last year, the Cassini spacecraft's narrow-angle camera recorded this stunning image of the vortex at the ringed planet's north pole. The false color, near-infrared image results in red hues for low clouds and green for high ones, causing the north-polar hurricane to take on the appearance of a rose. Enormous by terrestrial hurricane standards, this storm's eye is about 2,000 kilometers wide, with clouds at the outer edge traveling at over 500 kilometers per hour. The north pole Saturn hurricane swirls inside the large, six-sided weather pattern known as the hexagon. Of course, in 2006 Cassini also imaged the hurricane at Saturn's south pole. http://www.ciclops.org/view_event/191/ http://www.jpl.nasa.gov/news/news.php?release=2013-149 http://solarsystem.nasa.gov/news/display.cfm?News_ID=43464 http://saturn.jpl.nasa.gov/news/newsreleases/newsrelease20130429/ http://www.esa.int/Our_Activities/Space_Science/Cassini_eyes_Saturn_hurricane Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130502 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0502 http://asterisk.apod.com/viewtopic.php?t=31277

APOD: Horsehead: A Wider View (2013 May 03) Composition and Processing: Robert Gendler Image Data: ESO, VISTA, HLA, Hubble Heritage Team (STScI/AURA) http://apod.nasa.gov/apod/ap130503.html Explanation: Combined image data from the massive, ground-based VISTA telescope and the Hubble Space Telescope was used to create this wide perspective of the interstellar landscape surrounding the famous Horsehead Nebula. Captured at near-infrared wavelengths, the region's dusty molecular cloud sprawls across the scene that covers an angle about two-thirds the size of the Full Moon on the sky. Left to right the frame spans just over 10 light-years at the Horsehead's estimated distance of 1,600 light-years. Also known as Barnard 33, the still recognizable Horsehead Nebula stands at the upper right, the near-infrared glow of a dusty pillar topped with newborn stars. Below and left, the bright reflection nebula NGC 2023 is itself the illuminated environs of a hot young star. Dense clouds below the base of the Horsehead and on the outskirts of NGC 2023 show the tell-tale far red emission of energetic jets, known as Herbig-Haro objects, also associated with newborn stars. http://www.robgendlerastropics.com/HH-HST-ESO.html Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130503 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0503

APOD: A Supercell Thunderstorm Cloud Over Montana (2013 May 05) Image Credit & Copyright: Sean R. Heavey http://apod.nasa.gov/apod/ap130505.html Explanation: Is that a spaceship or a cloud? Although it may seem like an alien mothership, it's actually a impressive thunderstorm cloud called a supercell. Such colossal storm systems center on mesocyclones -- rotating updrafts that can span several kilometers and deliver torrential rain and high winds including tornadoes. Jagged sculptured clouds adorn the supercell's edge, while wind swept dust and rain dominate the center. A tree waits patiently in the foreground. The above supercell cloud was photographed in July west of Glasgow, Montana, USA, caused minor damage, and lasted several hours before moving on. http://www.seanrheavey.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130505 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0505

APOD: Tails of Comet Lemmon (2013 May 06) Image Credit & Copyright: Gerald Rhemann http://apod.nasa.gov/apod/ap130506.html Explanation: What caused the interestingly intricate tails that Comet Lemmon displayed earlier this year? First of all, just about every comet that nears the Sun displays two tails: a dust tail and an ion tail. Comet Lemmon's dust tail, visible above and around the comet nucleus in off-white, is produced by sun-light reflecting dust shed by the comet's heated nucleus. Flowing and more sculptured, however, is C/2012 F6 (Lemmon)'s blue ion tail, created by the solar wind pushing ions expelled by the nucleus away from the Sun. Also of note is the coma seen surrounding Comet Lemmon's nucleus, tinted green by atomic carbon gas fluorescing in sunlight. The above image was taken from the dark skies of Namibia in mid-April. Comet Lemmon is fading as it now heads back to the outer Solar System. http://www.astrostudio.at/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130506 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0506

APOD: Galaxy Cove Vista (2013 May 07) Image Credit & Copyright: Rogelio Bernal Andreo (Deep Sky Colors) http://apod.nasa.gov/apod/ap130507.html Explanation: To see a vista like this takes patience, hiking, and a camera. Patience was needed in searching out just the right place and waiting for just the right time. A short hike was needed to reach this rugged perch above a secluded cove in Julia Pfeiffer Burns State Park in California, USA. And a camera was needed for the long exposure required to bring out the faint light from stars and nebula in the background Milky Way galaxy. Moonlight and a brief artificial flash illuminated the hidden beach and inlet behind nearby trees in the above composite image taken about two weeks ago. Usually obscured McWay Falls is visible just below the image center, while the Pacific Ocean is in view to its right. http://www.deepskycolors.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130507 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0507

APOD: Ring of Fire over Monument Valley (2013 May 09) Image Credit & Copyright: Tunç Tezel (TWAN) http://apod.nasa.gov/apod/ap130509.html Explanation: As the New Moon continues this season's celestial shadow play, an annular solar eclipse track begins in western Australia at 22:30 UT on May 9 -- near sunrise on May 10 local time. Because the eclipse occurs within a few days of lunar apogee, the Moon's silhouette does not quite cover the Sun during mid-eclipse, momentarily creating a spectacular ring of fire. While a larger region witnesses a partial eclipse, the annular mid-eclipse phase is visible along a shadow track only about 200 kilometers wide but 13,000 kilometers long, extending across the central Pacific. For given locations along it, the ring of fire lasts from 4 to 6 minutes. Near the horizon, the appearance of the May 9/10 annular eclipse (online viewing) is suggested by this dramatic composite from May of 2012. The timelapse sequence depicts an annular eclipse in progress before sunset over Monument Valley in the southwestern United States. http://twanight.org/Tezel Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130509 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0509
