APOD: Milky Way above Atacama Salt Lagoon (2014 Sep 16) Image Credit & Copyright: Alex Tudorica (AIfA, U. Bonn) http://apod.nasa.gov/apod/ap140916.html Explanation: Galaxies, stars, and a serene reflecting pool combine to create this memorable land and skyscape. The featured panorama is a 12-image mosaic taken last month from the Salar de Atacama salt flat in northern Chile. The calm water is Laguna Cejar, a salty lagoon featuring a large central sinkhole. On the image left, the astrophotographer's fiancee is seen capturing the same photogenic scene. The night sky is lit up with countless stars, the Large and Small Magellanic Cloud galaxies on the left, and the band of our Milky Way galaxy running diagonally up the right. The Milky Way may appear to be causing havoc at the horizon, but those are just the normal lights of a nearby town. https://www.flickr.com/photos/27891676@N05 http://www.astro.uni-bonn.de/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=140916 #APOD

APOD: The Butterfly Nebula from Hubble (2014 Oct 01) Image Credit: NASA, ESA, and the Hubble SM4 ERO Team; Reprocessing & Copyright: Francesco Antonucci http://apod.nasa.gov/apod/ap141001.html Explanation: The bright clusters and nebulae of planet Earth's night sky are often named for flowers or insects. Though its wingspan covers over 3 light-years, NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees C, the dying central star of this particular planetary nebula has become exceptionally hot, shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust. This sharp close-up of the dying star's nebula was recorded in 2009 by the Hubble Space Telescope's Wide Field Camera 3, and is presented here in reprocessed colors. Cutting across a bright cavity of ionized gas, the dust torus surrounding the central star is near the center of this view, almost edge-on to the line-of-sight. Molecular hydrogen has been detected in the hot star's dusty cosmic shroud. NGC 6302 lies about 4,000 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius). http://www.nasa.gov/ http://www.spacetelescope.org/ http://hubblesite.org/servicing_mission_4/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=141001 #APOD

APOD: From the Temple of the Sun to the Temple of the Moon (2014 Oct 07) Image Credit & Copyright: Dave Lane http://apod.nasa.gov/apod/ap141007.html Explanation: What connects the Sun to the Moon? Many answers have been given throughout history, but in the case of today's featured image, it appears to be the plane of our Milky Way Galaxy. The 16-image panorama was taken in Capitol Reef National Park, Utah, USA where two sandstone monoliths -- the Temple of the Moon on the right and the Temple of the Sun on the left -- rise dramatically from the desert. Each natural monument stands about 100 meters tall and survives from the Jurassic period 160 million years ago. Even older are many of the stars and nebula that dot the celestial background, including the Andromeda Galaxy. Tomorrow the Earth will connect the Sun to the Moon by way of its shadow: a total lunar eclipse will be visible from many locations around the globe. https://www.facebook.com/david.lane.520562 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=141007 #APOD

APOD: The Helix Nebula from Blanco and Hubble (2014 Oct 12) Image Credit: C. R. O'Dell, (Vanderbilt) et al. ESA, NOAO, NASA http://apod.nasa.gov/apod/ap141012.html Explanation: How did a star create the Helix nebula? The shapes of planetary nebula like the Helix are important because they likely hold clues to how stars like the Sun end their lives. Observations by the orbiting Hubble Space Telescope and the 4-meter Blanco Telescope in Chile, however, have shown the Helix is not really a simple helix. Rather, it incorporates two nearly perpendicular disks as well as arcs, shocks, and even features not well understood. Even so, many strikingly geometric symmetries remain. How a single Sun-like star created such beautiful yet geometric complexity is a topic of research. The Helix Nebula is the nearest planetary nebula to Earth, lies only about 700 light years away toward the constellation of Aquarius, and spans about 3 light-years. http://www.physics.vanderbilt.edu/cv/odell.html http://www.vanderbilt.edu/physics/index.php http://www.spacetelescope.org/ http://www.noao.edu/ http://www.nasa.gov/ 2015 APOD Calendar: Nebulas and Star Clusters http://friendsofapod.org/?page_id=42 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=141012 #APOD

APOD: Auroral Corona over Norway (2014 Oct 14) Image Credit & Copyright: Harald Albrigtsen http://apod.nasa.gov/apod/ap141014.html Explanation: Higher than the highest mountain lies the realm of the aurora. Auroras rarely reach below 60 kilometers, and can range up to 1000 kilometers. Aurora light results from energetic electrons and protons striking atoms and molecules in the Earth's atmosphere. Somewhat uncommon, an auroral corona appears as a center point for a surrounding display and may occur when an aurora develops directly overhead, or when auroral rays are pointed nearly toward the observer. This picturesque but brief green and purple aurora exhibition occurred last month high above Kvaløya, Tromsø, Norway. The Sessøyfjorden fjord runs through the foreground, while numerous stars are visible far in the distance. 2015 APOD Calendar: Land and Skyscapes http://friendsofapod.org/?page_id=42 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=141014 #APOD
