APOD: Roll Cloud Over Wisconsin (2013 Aug 08) Image Credit: Megan Hanrahan (Pierre cb), Wikipedia http://apod.nasa.gov/apod/fap/ap130908.html Explanation: What kind of cloud is this? A type of arcus cloud called a roll cloud. These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. Unlike a similar shelf cloud, a roll cloud is completely detached from their parent cumulonimbus cloud. Pictured above, a roll cloud extends far into the distance as a storm approached in 2007 in Racine, Wisconsin, USA. http://en.wikipedia.org/wiki/File:Roll-Cloud-Racine.jpg Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130908 #APOD

APOD: A Flight through the Hubble Ultra Deep Field (2013 Aug 27) Video Credit: NASA>, ESA, F. Summers, Z. Levay, L. Frattare, B. Mobasher, A. Koekemoer and the HUDF Team (STScI) http://apod.nasa.gov/apod/ap130827.html http://www.youtube.com/watch?v=PDMp8a-YNe0 Explanation: What would it look like to fly through the distant universe? To find out, a team of astronomers estimated the relative distances to over 5,000 galaxies in one of the most distant fields of galaxies ever imaged: the Hubble Ultra Deep Field (HUDF). Because it takes light a long time to cross the universe, most galaxies visible in the above video are seen when the universe was only a fraction of its current age, were still forming, and have unusual shapes when compared to modern galaxies. No mature looking spiral galaxies such as our Milky Way or the Andromeda galaxy yet exist. Toward the end of the video the virtual observer flies past the furthest galaxies in the HUDF field, recorded to have a redshift past 8. This early class of low luminosity galaxies likely contained energetic stars emitting light that transformed much of the remaining normal matter in the universe from a cold gas to a hot ionized plasma. http://hubblesite.org/news/2004/28 http://hubblesite.org/news/2004/07 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130827 #APOD

APOD: Bright Planetary Nebula NGC 7027 from Hubble (2013 Aug 26) Image Credit: Hubble Legacy Archive, ESA, NASA; Processing: Delio Tolivia Cadrecha http://apod.nasa.gov/apod/ap130826.html Explanation: It is one of the brightest planetary nebulae on the sky -- what should it be named? First discovered in 1878, nebula NGC 7027 can be seen toward the constellation of the Swan (Cygnus) with a standard backyard telescope. Partly because it appears there as only an indistinct spot, it is rarely referred to with a moniker. When imaged with the Earth-orbiting Hubble Space Telescope, however, great details are revealed. Studying Hubble images of NGC 7027 have led to the understanding that it is a planetary nebula that began expanding about 600 years ago, and that the cloud of gas and dust is unusually massive as it appears to contain about three times the mass of our Sun. Pictured above in assigned colors, the resolved, layered, and dust-laced features of NGC 7027 might remind sky enthusiasts of a familiar icon that could be the basis for an informal name. Please feel free to make suggestions -- some suggestions are being recorded, for example, in an online APOD discussion forum. http://www.facebook.com/delio.cadrecha Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130826 #APOD

Build Your Own Fire Tornado

Build Your Own Fire Tornado<p>Fire whirls often happen during wildland fires. They’re usually small, but under the right conditions, big ones form. Huge whirls have been recorded climbing to heights over 3,000 feet, with wind speeds exceeding 155mph — equivalent to an F3 tornado.<p>Meteorologists call any such phenomenon a vortex, which is just a volume of rotating fluid. Examples include smoke rings, water going down a drain, and dust devils.<p>In fact, fire whirls and dust devils are very similar. …

APOD: A Spectrum of Nova Delphini (2013 Aug 23) Image Credit & Copyright: Jürg Alean http://apod.nasa.gov/apod/ap130823.html Explanation: When a new star appeared in the constellation Delphinus late last week, astronomers found its spectrum hinted at the apparition's true nature. Now known as Nova Delphini, its visible light spectrum near maximum brightness is centered in this image of the nearby star field captured with prism and telescope on the night of August 16/17 at the Sternwarte Bülach, Switzerland. Strong absorption lines due to hydrogen atoms are seen as the darkest bands in the nova's spectrum, but the strong absorption lines are bordered along their redward edge by bright bands of emission. That pattern is the spectral signature of material blasted from a catalysmic binary system known as a classical nova. Other stars in field are fainter, identified by their Hipparcus catalog numbers, brightness in magnitudes, and spectral types. By chance, the faint emission line from planetary nebula NGC 6905 was also included, indicated at the lower right. http://swisseduc.ch/about/redaktion/alean-juerg.html Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130823 #APOD

APOD: IC 5067 in the Pelican Nebula (2013 Aug 22) Image Credit & Copyright: César Blanco González http://apod.nasa.gov/apod/ap130822.html Explanation: The prominent ridge of emission featured in this dramatic skyscape is cataloged as IC 5067. Part of a larger emission nebula with a distinctive shape, popularly called The Pelican Nebula, the ridge spans about 10 light-years following the curve of the cosmic pelican's head and neck. This false color view also translates the pervasive glow of narrow emission lines from atoms in the nebula to a color palette made popular in Hubble Space Telescope images of star forming regions. Fantastic, dark shapes inhabiting the 1/2 degree wide field are clouds of cool gas and dust sculpted by the winds and radiation from hot, massive stars. Close-ups of some of the sculpted clouds show clear signs of newly forming stars. The Pelican Nebula, itself cataloged as IC 5070, is about 2,000 light-years away. To find it, look northeast of bright star Deneb in the high flying constellation Cygnus. http://www.cieloprofundo.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130822 #APOD

APOD: Perseid Meteors Over China (2013 Aug 21) Image Credit & Copyright: Xiang Zhan (Beijing Planetarium) http://apod.nasa.gov/apod/ap130821.html Explanation: Comet dust rained down on planet Earth earlier this month, streaking through dark skies in the annual Perseid meteor shower. While enjoying the anticipated space weather above Zhangbei Prairie, Hebei Province, China, astronomer Xiang Zhan recorded a series of 10 second long exposures spanning four hours on the night of August 12/13 using a wide angle lens. Combining frames which captured 68 meteor flashes, he produced the above composite view of the Perseids of summer. Although the sand-sized comet particles are traveling parallel to each other, the resulting shower meteors clearly seem to radiate from a single point on the sky in the eponymous constellation Perseus. The radiant effect is due to perspective, as the parallel tracks appear to converge at a distance. The next notable meteor shower may be the Orionids in late October. http://www.bjp.org.cn/en/? http://asterisk.apod.com/viewtopic.php?f=29&t=31912 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130821 #APOD

APOD: Venus and the Triply Ultraviolet Sun (2013 Aug 20) Image Credit: NASA/SDO & the AIA, EVE, and HMI teams; Digital Composition: Peter L. Dove http://apod.nasa.gov/apod/ap130820.html Explanation: An unusual type of solar eclipse occurred last year. Usually it is the Earth's Moon that eclipses the Sun. Last June, most unusually, the planet Venus took a turn. Like a solar eclipse by the Moon, the phase of Venus became a continually thinner crescent as Venus became increasingly better aligned with the Sun. Eventually the alignment became perfect and the phase of Venus dropped to zero. The dark spot of Venus crossed our parent star. The situation could technically be labeled a Venusian annular eclipse with an extraordinarily large ring of fire. Pictured above during the occultation, the Sun was imaged in three colors of ultraviolet light by the Earth-orbiting Solar Dynamics Observatory, with the dark region toward the right corresponding to a coronal hole. Hours later, as Venus continued in its orbit, a slight crescent phase appeared again. The next Venusian solar eclipse will occur in 2117. http://www.nasa.gov/ http://sdo.gsfc.nasa.gov/mission/about.php http://www.flickr.com/photos/pldove/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130820 #APOD
