APOD: In the Center of the Trifid Nebula (2013 Jan 28) Image Credit: Subaru Telescope (NAOJ), Hubble Space Telescope, Martin Pugh; Processing: Robert Gendler http://apod.nasa.gov/apod/ap130128.html Explanation: Clouds of glowing gas mingle with dust lanes in the Trifid Nebula, a star forming region toward the constellation of the Archer (Sagittarius). In the center, the three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque dust appear on the right, while other dark filaments of dust are visible threaded throughout the nebula. A single massive star visible near the center causes much of the Trifid's glow. The Trifid, also known as M20, is only about 300,000 years old, making it among the youngest emission nebulae known. The nebula lies about 9,000 light years away and the part pictured here spans about 10 light years. The above image is a composite with luminance taken from an image by the 8.2-m ground-based Subaru Telescope, detail provided by the 2.4-m orbiting Hubble Space Telescope, color data provided by Martin Pugh and image assembly and processing provided by Robert Gendler. http://www.martinpughastrophotography.id.au/ http://www.robgendlerastropics.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130128 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0128

APOD: A Year on the Sun (2013 Apr 26) Image Credit: NASA, Solar Dynamics Observatory http://apod.nasa.gov/apod/ap130426.html Explanation: Our solar system's miasma of incandescent plasma, the Sun may look a little scary here. The picture is a composite of 25 images recorded in extreme ultraviolet light by the orbiting Solar Dynamics Observatory between April 16, 2012 and April 15, 2013. The particular wavelength of light, 171 angstroms, shows emission from highly ionized iron atoms in the solar corona at a characteristic temperatures of about 600,000 kelvins (about 1 million degrees F). Girdling both sides of the equator during the approach to maximum in its 11-year solar cycle, the solar active regions are laced with bright loops and arcs along magnetic field lines. Of course, a more familiar visible light view would show the bright active regions as groups of dark sunspots. Three years of Solar Dynamics Observatory images are compressed into this short video. http://www.nasa.gov/mission_pages/sdo/news/first-light-3rd.html http://www.youtube.com/watch?v=dHvPJp9YFfY Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130426 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0426

APOD: Earth's Richat Structure (2013 May 19) Image Credit: NASA/GSFC/METI/Japan Space Systems, and U.S./Japan ASTER Science Team http://apod.nasa.gov/apod/ap130519.html Explanation: What on Earth is that? The Richat Structure in the Sahara Desert of Mauritania is easily visible from space because it is nearly 50 kilometers across. Once thought to be an impact crater, the Richat Structure's flat middle and lack of shock-altered rock indicates otherwise. The possibility that the Richat Structure was formed by a volcanic eruption also seems improbable because of the lack of a dome of igneous or volcanic rock. Rather, the layered sedimentary rock of the Richat structure is now thought by many to have been caused by uplifted rock sculpted by erosion. The above image was captured by the ASTER instruments onboard the orbiting orbiting Terra satellite. Why the Richat Structure is nearly circular remains a mystery. http://asterweb.jpl.nasa.gov/gallery-detail.asp?name=Richat Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130519 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0519

APOD: The Red Rectangle Nebula from Hubble (2013 May 21) Image Credit: ESA, Hubble, NASA; Reprocessing: Steven Marx, Hubble Legacy Archive http://apod.nasa.gov/apod/ap130521.html Explanation: How was the unusual Red Rectangle nebula created? At the nebula's center is an aging binary star system that surely powers the nebula but does not, as yet, explain its colors. The unusual shape of the Red Rectangle is likely due to a thick dust torus which pinches the otherwise spherical outflow into tip-touching cone shapes. Because we view the torus edge-on, the boundary edges of the cone shapes seem to form an X. The distinct rungs suggest the outflow occurs in fits and starts. The unusual colors of the nebula are less well understood, however, and speculation holds that they are partly provided by hydrocarbon molecules that may actually be building blocks for organic life. The Red Rectangle nebula lies about 2,300 light years away towards the constellation of the Unicorn (Monoceros). The nebula is shown above in great detail as recently reprocessed image from Hubble Space Telescope. In a few million years, as one of the central stars becomes further depleted of nuclear fuel, the Red Rectangle nebula will likely bloom into a planetary nebula. http://www.astrobin.com/users/StevenMx/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130521 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0521

APOD: Blue Sun Bursting (2013 May 20) Image Credit & Copyright: Alan Friedman (Averted Imagination) http://apod.nasa.gov/apod/ap130520.html Explanation: Our Sun is not a giant blueberry. Our Sun can be made to appear similar to the diminutive fruit, however, by imaging it in a specific color of extreme violet light called CaK that is emitted by the very slight abundance of ionized Calcium in the Sun's atmosphere, and then false color-inverting the image. This solar depiction is actually scientifically illuminating as a level of the Sun's chromosphere appears quite prominent, showing a crackly textured surface, cool sunspots appearing distinctly bright, and surrounding hot active regions appearing distinctly dark. The Sun is currently near the maximum activity level in its 11 year cycle, and has emitted powerful flares over the past week. During times of high activity, streams of energetic particles from Sun may impact the Earth's magnetosphere and set off spectacular auroras. http://www.avertedimagination.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130520 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0520

APOD: All of Mercury (2013 Jun 12) Image Credit: NASA / JHU-APL / CIW http://apod.nasa.gov/apod/ap130612.html http://www.youtube.com/watch?v=DmYK479EpQc Explanation: For the first time, the entire surface of planet Mercury has been mapped. Detailed observations of the innermost planet's surprising crust have been ongoing since the robotic MESSENGER spacecraft first passed Mercury in 2008 and began orbiting in 2011. Previously, much of the Mercury's surface was unknown as it is too far for Earth-bound telescopes to see clearly, while the Mariner 10 flybys in the 1970s observed only about half. The above video is a compilation of thousands of images of Mercury rendered in exaggerated colors to better contrast different surface features. Visible on the rotating world are rays emanating from a northern impact that stretch across much of the planet, while about half-way through the video the light colored Caloris Basin rotates into view, a northern ancient impact feature that filled with lava. MESSENGER has now successfully completed its primary and first extended missions. http://photojournal.jpl.nasa.gov/catalog/PIA16850 http://photojournal.jpl.nasa.gov/catalog/PIA16852 http://photojournal.jpl.nasa.gov/catalog/PIA16853 APOD: Colors of Mercury (2013 Mar 01) http://apod.nasa.gov/apod/ap130301.html Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130612 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0612

APOD: Saturn's Hyperion: A Moon with Odd Craters (2013 Jun 30) Image Credit & Copyright: Cassini Imaging Team, SSI, JPL, ESA, NASA http://apod.nasa.gov/apod/ap130630.html Explanation: What lies at the bottom of Hyperion's strange craters? Nobody's sure. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon in 2005 and 2010 and took images of unprecedented detail. An image from the 2005 pass, shown above in false color, shows a remarkable world strewn with strange craters and a generally odd surface. The slight differences in color likely show differences in surface composition. At the bottom of most craters lies some type of unknown dark material. Inspection of the image shows bright features indicating that the dark material might be only tens of meters thick in some places. Hyperion is about 250 kilometers across, rotates chaotically, and has a density so low that it might house a vast system of caverns inside. http://ciclops.org/view.php?id=1507 http://photojournal.jpl.nasa.gov/catalog/PIA07740 http://saturn.jpl.nasa.gov/science/moons/hyperion/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130630 #APOD

APOD: Hidden Galaxy IC 342 (2013 Jul 18) Image Credit & Copyright: Stephen Leshin http://apod.nasa.gov/apod/ap130718.html Explanation: Similar in size to large, bright spiral galaxies in our neighborhood, IC 342 is a mere 10 million light-years distant in the long-necked, northern constellation Camelopardalis. A sprawling island universe, IC 342 would otherwise be a prominent galaxy in our night sky, but it is hidden from clear view and only glimpsed through the veil of stars, gas and dust clouds along the plane of our own Milky Way galaxy. Even though IC 342's light is dimmed by intervening cosmic clouds, this deep telescopic image traces the galaxy's obscuring dust, blue star clusters, and glowing pink star forming regions along spiral arms that wind far from the galaxy's core. IC 342 may have undergone a recent burst of star formation activity and is close enough to have gravitationally influenced the evolution of the local group of galaxies and the Milky Way. http://sleshin.startlogic.com/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130718 #APOD

APOD: The Seasons of Saturn (2013 Jul 21) Image Credit: R. G. French (Wellesley College) et al., NASA, ESA, and The Hubble Heritage Team (STScI/AURA) http://apod.nasa.gov/apod/ap130721.html Explanation: Since Saturn's axis is tilted as it orbits the Sun, Saturn has seasons, like those of planet Earth ... but Saturn's seasons last for over seven years. So what season is it on Saturn now? Orbiting the equator, the tilt of the rings of Saturn provides quite a graphic seasonal display. Each year until 2016, Saturn's rings will be increasingly apparent after appearing nearly edge-on in 2009. The ringed planet is also well placed in evening skies providing a grand view as summer comes to Saturn's northern hemisphere and winter to the south. The Hubble Space Telescope took the above sequence of images about a year apart, starting on the left in 1996 and ending on the right in 2000. Although they look solid, Saturn's Rings are likely less than 50 meters thick and consist of individually orbiting bits of ice and rock ranging in size from grains of sand to barn-sized boulders. http://heritage.stsci.edu/2001/15/ http://hubblesite.org/news/2001/15 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130721 #APOD

APOD: Earth and Moon from Saturn (2013 Jul 22) Image Credit: NASA/JPL-Caltech/Space Science Institute http://apod.nasa.gov/apod/ap130722.html Explanation: You are here. Everyone you've ever known is here. Every human who has ever lived -- is here. Pictured above is the Earth-Moon system as captured by the Cassini mission orbiting Saturn in the outer Solar System. Earth is the brighter and bluer of the two spots near the center, while the Moon is visible to its lower right. Images of Earth from Saturn were taken on Friday. Quickly released unprocessed images were released Saturday showing several streaks that are not stars but rather cosmic rays that struck the digital camera while it was taking the image. The above processed image was released earlier today. At nearly the same time, many humans on Earth were snapping their own pictures of Saturn. http://photojournal.jpl.nasa.gov/catalog/PIA17170 Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130722 #APOD

APOD: The Beautiful Trifid (2013 Jul 25) Image Credit & Copyright: Máximo Ruiz http://apod.nasa.gov/apod/ap130725.html Explanation: The beautiful Trifid Nebula is a cosmic study in contrasts. Also known as M20, it lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star forming region in the plane of our galaxy, the Trifid illustrates three different types of astronomical nebulae; red emission nebulae dominated by light emitted by hydrogen atoms, blue reflection nebulae produced by dust reflecting starlight, and dark nebulae where dense dust clouds appear in silhouette. The bright red emission region, roughly separated into three parts by obscuring dust lanes, lends the Trifid its popular name. But in this sharp, colorful scene, the red emission is also surrounded by the the telltale blue haze of reflection nebulae. Pillars and jets sculpted by newborn stars, below and left of the emission nebula's center, appear in Hubble Space Telescope close-up images of the region. The Trifid Nebula is about 40 light-years across. http://www.astromodelismo.es/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130725 #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
