(Space Fellowship) Rosetta's Comet Scrambling Its Jets

This image of comet 67P/Churyumov-Gerasimenko, taken by Rosetta's Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) on Sept. 20, from a distance of 4.5 miles (7.2 kilometers), shows jets of dust and gas streaming into space from the neck of the comet's nucleus. Images of the comet nucleus, taken by Rosetta earlier in the summer, showed that the distinct jets of dust and gas emanating from the comet were originated from the neck region, which connects the comet's two lobes. &nbsp;[...]<div class="feedflare"> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=WvWS0xXGckw:VlFvtGDaqAs:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/ISF?d=yIl2AUoC8zA" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=WvWS0xXGckw:VlFvtGDaqAs:-BTjWOF_DHI"><img src="http://feeds.feedburner.com/~ff/ISF?i=WvWS0xXGckw:VlFvtGDaqAs:-BTjWOF_DHI" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=WvWS0xXGckw:VlFvtGDaqAs:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/ISF?i=WvWS0xXGckw:VlFvtGDaqAs:V_sGLiPBpWU" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=WvWS0xXGckw:VlFvtGDaqAs:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/ISF?d=qj6IDK7rITs" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=WvWS0xXGckw:VlFvtGDaqAs:gIN9vFwOqvQ"><img src="http://feeds.feedburner.com/~ff/ISF?i=WvWS0xXGckw:VlFvtGDaqAs:gIN9vFwOqvQ" border="0"></a> </div><img src="http://feeds.feedburner.com/~r/ISF/~4/WvWS0xXGckw" height="1" width="1"/>

(Space Fellowship) Sunspots and Solar Eclipse

A New Moon joined giant sunspot group AR 2192 to dim the bright solar disk during Thursday's much anticipated partial solar eclipse. Visible from much of North America, the Moon's broad silhouette is captured in this extreme telephoto snapshot near eclipse maximum from Santa Cruz, California. About the size of Jupiter, the remarkable AR 2192 itself darkens a noticeable fraction of the Sun, near center and below the curved lunar limb. As the sunspot group slowly rotates across the Sun and out&nbsp;[...]<div class="feedflare"> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=UXdVmuH0wzM:xpuEYoQw--s:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/ISF?d=yIl2AUoC8zA" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=UXdVmuH0wzM:xpuEYoQw--s:-BTjWOF_DHI"><img src="http://feeds.feedburner.com/~ff/ISF?i=UXdVmuH0wzM:xpuEYoQw--s:-BTjWOF_DHI" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=UXdVmuH0wzM:xpuEYoQw--s:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/ISF?i=UXdVmuH0wzM:xpuEYoQw--s:V_sGLiPBpWU" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=UXdVmuH0wzM:xpuEYoQw--s:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/ISF?d=qj6IDK7rITs" border="0"></a> <a rel="nofollow" target="_blank" href="http://feeds.feedburner.com/~ff/ISF?a=UXdVmuH0wzM:xpuEYoQw--s:gIN9vFwOqvQ"><img src="http://feeds.feedburner.com/~ff/ISF?i=UXdVmuH0wzM:xpuEYoQw--s:gIN9vFwOqvQ" border="0"></a> </div><img src="http://feeds.feedburner.com/~r/ISF/~4/UXdVmuH0wzM" height="1" width="1"/>

(ScienceDaily) NASA identifies ice cloud above cruising altitude on Titan

NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles.<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/IhskMLnGpSU" height="1" width="1"/>

(ScienceDaily) NASA's Fermi satellite finds hints of starquakes in magnetar 'storm'

NASA's Fermi Gamma-ray Space Telescope detected a rapid-fire "storm" of high-energy blasts from a highly magnetized neutron star, also called a magnetar, on Jan. 22, 2009. Now astronomers analyzing this data have discovered underlying signals related to seismic waves rippling throughout the magnetar.<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/cRT-ygd8FO0" height="1" width="1"/>

(ScienceDaily) Illusions in the cosmic clouds: New image of spinning neutron star

Pareidolia is the psychological phenomenon where people see recognizable shapes in clouds, rock formations, or otherwise unrelated objects or data. There are many examples of this phenomenon on Earth and in space.<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/NsQMUyJ-4-w" height="1" width="1"/>

(ScienceDaily) MAVEN ultraviolet image of comet Siding Spring's hydrogen coma

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft obtained this ultraviolet image of hydrogen surrounding comet C/2013 A1 Siding Spring on Oct. 17, 2014, two days before the comet's closest approach to Mars. The Imaging Ultraviolet Spectrograph (IUVS) instrument imaged the comet at a distance of 5.3 million miles (8.5 million kilometers).<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/ACpjxEzk3wo" height="1" width="1"/>

(ScienceDaily) Mars Orbiter's spectrometer shows Oort comet's coma

The Compact Imaging Spectrometer for Mars (CRISM) observed comet C/2013 A1 Siding Spring as the comet sped close to Mars on Oct. 19. CRISM recorded imaging data in 107 different wavelengths, showing the inner part of the cloud of dust, called the coma, surrounding the comet's nucleus.<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/Wamh1Kcgv70" height="1" width="1"/>

(ScienceDaily) Galactic wheel of life shines in infrared

It might look like a spoked wheel or even a "Chakram" weapon wielded by warriors like "Xena," from the fictional TV show, but this ringed galaxy is actually a vast place of stellar life. A newly released image from NASA's Spitzer Space Telescope shows the galaxy NGC 1291. Though the galaxy is quite old, roughly 12 billion years, it is marked by an unusual ring where newborn stars are igniting.<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/d2H2a6O52OE" height="1" width="1"/>

(ScienceDaily) NASA ultra-black nano-coating to be applied to 3-D new solar coronagraph

An emerging super-black nanotechnology that is to be tested for the first time this fall on the International Space Station will be applied to a complex, 3-D component critical for suppressing stray light in a new, smaller, less-expensive solar coronagraph designed to ultimately fly on the orbiting outpost or as a hosted payload on a commercial satellite.<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/KL0vMEdTB1s" height="1" width="1"/>

(ScienceDaily) Mass gaging system will measure fuel transfer in zero gravity

Transfer of super-cooled or cryogenic fuel from one tank to another in the zero gravity of space may one day be a reality. But the challenges of measuring fuels and fuel levels in the weightlessness of space must be solved first. A newly developed sensor technology that will be tested on the early suborbital flights of Virgin Galactic's SpaceShipTwo in 2015.<img src="http://feeds.feedburner.com/~r/sciencedaily/space_time/~4/VqN2B7dxv4o" height="1" width="1"/>
