Andromeda: born out of a massive collision? – Was the Andromeda Galaxy, the largest and most massive galaxy in our local neighborhood, shaped into its current structure due to a monstrous collision over 6 billion years ago? According to a new study by some French astronomers, the answer is oui. -Phil Plait / Bad Astronomy

How big is Pluto, anyway? – These days, a question like that is easy to answer: type it in to Google, click on the Wikipeadia entry, and read the answer: 2306 +/- 20 km. The +/- (to be read “plus or minus”) is important here: every measurement has limitations and an often critical part of science is correctly quantifying those limit. The correct interpretation of 2306 +/- 20 km is that 2306 km is the most likely value, but, within a certain range of probability, the value could be as low as 2286 or as high as 2326 km. The value could still be higher or lower, but the probability is small. -Mike Brown

NASA’s Stardust Spacecraft Burns for Another Comet Flyby – Eighty-six days out from its appointment with a comet, NASA’s Stardust spacecraft fired its thrusters to help refine its flight path.

Why Making Neutral Antimatter is Such A Big Deal! – Antimatter is some of the most wonderful stuff in the Universe. All of the normal matter on Earth — that you’re used to — is made up of atoms, which in turn are made of protons, neutrons, and electrons, like so. But every particle that exists, whether it’s a fundamental particle (like a quark, electron, or photon) or a composite particle (like a neutron or proton), also has an antiparticle! -Ethan Siegel / Science Blogs

Spitzer Reveals a Buried Explosion Sparked by a Galactic Train Wreck
– Astronomers using NASA’s Spitzer Space Telescope have found a stunning burst of star formation that beams out as much infrared light as an entire galaxy. The collision of two spiral galaxies has triggered this explosion, which is cloaked by dust that renders its stars nearly invisible in other wavelengths of light. -Adam Hadhazy – Spitzer Space Telescope / NASA

Making stars: Studies show how cosmic dust and gas shape galaxy evolution – Astronomers find cosmic dust annoying when it blocks their view of the heavens, but without it the universe would be devoid of stars. Cosmic dust is the indispensable ingredient for making stars and for understanding how primordial diffuse gas clouds assemble themselves into full–blown galaxies. -University of Chicago

The Atmosphere of WASP-17b – One of the greatest potentials of transiting exoplanets is the ability to monitor the spectra and examine the composition of the planet‘s atmosphere. This has been done already for HD 18733b and HD 209458b. In a new article by a team of astronomers at Keele University in the UK, absorption spectroscopy has been applied to the unusual exoplanet WASP-17b, which is known to orbit retrograde. -Jon Voisey / Universe Today

Delta IV Heavy Roars Off Launch Pad on Secret NRO Mission – United Launch Alliance (ULA) successfully launched a Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida, sending a classified surveillance satellite to space. Liftoff occurred on Nov. 21 at 5:58 p.m. EDT. The enormous rocket thundered to life, and as almost to underscore the secretive nature of the mission, the fiery exhaust was only visible for a short while before disappearing into thick clouds. However, long after the rocket was out of view, it made its journey known through its roar. The vibration was so visceral that vehicles and windows of buildings in the immediate area began to rattle with the raw power that was unleashed. -Jason Rhian / Universe Today

BRIAN MARSDEN (1937 Aug. 5-2010 Nov. 18) – Brian Geoffrey Marsden was born on 1937 August 5 in Cambridge, England. His father, Thomas, was the senior mathematics teacher at a local high school. It was his mother, Eileen (nee West), however, who introduced him to the study of astronomy, when he returned home on the Thursday during his first week in primary school in 1942 and found her sitting in the back yard watching an eclipse of the sun. Using now frowned-upon candle-smoked glass, they sat watching the changing bite out of the sun. What most impressed the budding astronomer, however, was not that the eclipse could be seen, but the fact that it had been predicted in advance, and it was the idea that one could make successful predictions of events in the sky that eventually led him to his career. -M.P.E.C. 2010-W10 / Minor Planet Center

Exoplanet of Extragalactic Origin Could Foretell Our Solar System’s Future – While astronomers have detected over 500 extrasolar planets during the past 15 years, this latest one might have the most storied and unusual past. But its future is also of great interest, as it could mirror the way our own solar system might meet its demise. This Jupiter-like planet, called HIP 13044 b, is orbiting a star that used to be in another galaxy but that galaxy was swallowed by the Milky Way. While astronomers have never directly detected an exoplanet in another galaxy, this offers evidence that other galaxies host stars with planets, too. The star is nearing the end of its life and as it expands, could engulf the planet, just as our Sun will likely snuff out our own world. And somehow, this exoplanet has survived the first death throes of the star. -Nancy Atkinson / Universe Today

A comet creates its own snowstorm – NASA has just released new results and images from the EPOXI spacecraft’s visit to the comet Hartley 2 from November 4… and like the previous ones, these are absolutely stunning jaw-droppers. What scientists have found is that the comet’s solid nucleus is sitting in the middle of a veritable snowstorm! -Phil PlaitBad Astronomy

Hubble Captures New ‘Life’ in an Ancient Galaxy – New observations with NASA’s Hubble Space Telescope are helping to show that elliptical galaxies still have some youthful vigor left, thanks to encounters with smaller galaxies. Images of the core of NGC 4150, taken in near-ultraviolet light with the sharp-eyed Wide Field Camera 3 (WFC3), reveal streamers of dust and gas and clumps of young, blue stars that are significantly less than a billion years old. Evidence shows that the star birth was sparked by a merger with a dwarf galaxy. -NASA

Scientists say the data collected by the EPOXI mission of comet Hartley 2 are as revealing as the pictures taken on the spacecraft's recent flyby. The spacecraft passed Hartley 2 at an altitude of about 435 miles from the comet's surface, close enough to reveal details of its nucleus and give scientists the most extensive look at a comet in history. Comets are remnants of the formation of our solar system more than 4-and-a-half-billion years old.

The STEREO (Behind) spacecraft observed no fewer than four flares (and likely five) from one active region over about a 30-hour period (Nov. 6-7, 2010). These were minor to medium-sized flares, but even so they still overwhelmed the telescope sensors enough to cause artifacts of light seen as quick streaks as well as staggered, carat-shaped brightenings, which are the diffraction pattern off the internal structures in the EUVI telescope (see still image). Flares are brief but intense solar storms that are known to blast radiation into space, but not a lot of plasma particles - Courtesy of SOHO/STEREO (Behind) consortium. SOHO is a project of international cooperation between ESA and NASA

At NASA's Kennedy Space Center's Launch Pad 39A, technicians are completing repairs on space shuttle Discovery's ground umbilical carrier plate (GUCP). On Nov. 17, the hydrogen vent line was reattached to the GUCP. That vent pipe carries excess hydrogen gas safely away from Discovery to a flare stack, where it is burned off. Teams will analyze the hardware fittings and pressure check the connections to look for any possible leaks. Discovery's next launch window for STS-133 extends from Nov. 30 through Dec. 6.
