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

Europe maintains its presence on the final frontier – ESA has decided to extend the productive lives of 11 of its operating space science missions. This will enable ESA’s world-class science missions to continue returning pioneering results until at least 2014. -ESA


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

Interacting galaxies known as II Zw 096

A brilliant burst of star formation is revealed in this image combining observations from NASA's Spitzer and Hubble Space Telescopes. The collision of two spiral galaxies, has triggered this luminous starburst, the brightest ever seen taking place far away from the centers, or nuclei, of merging galaxies.

Sunset on Mars – I know, it may not look like much, but think about what you’re seeing: a sunset on another world. And those images were taken by a robotic probe that took years to design and build, months to travel the hundreds of millions of kilometers to get to Mars, a harrowing few minutes to descend on a breath of fire through the thin air to land on the surface, and then nearly seven years to travel the landscape long, long past its design specifications. -Phil Plait / Bad Astronomy

Space Shuttle Era: The Ground Umbilical Carrier Plate (GUCP) - The Ground Umbilical Carrier Plate provides one of the critical connections between the shuttle and the launch pad. The GUCP, pronounced "Gup" helps funnel gaseous hydrogen from the external tank into a system of pipes that safely burns off the excess fuel. Launch controllers track the readings from sensors on the GUCP for signs of a hydrogen leak. When readings are outside the limits, the countdown is halted so technicians can make repairs.

Animation of Deep Impact close-approach images - About an hour after its closest approach of Hartley 2, Deep Impact downlinked five precious images taken during the nearest part of its flyby. The top two images were taken 82 and 16 seconds before closest approach, and the bottom three 18, 57, and 117 seconds after closest approach (image times are 13:58:07, 13:59:13, 13:59:47, 14:00:26, and 14:01:26 UTC on November 4, 2010).

Discovery launch scrubbed again due to LH2 leak

Update 2: FURTHER DELAY. Shuttle Discovery won’t fly before November 30 at 09:05 UTC.
Update 1: The teams are now working a 72 hour scrub turnaround procedure instead of the 48 they originally started to call. The earliest opportunity for Discovery to launch will be on Monday, Nov 8.

Nov 5, 2010 – The launch of Space Shuttle Discovery has been officially scrubbed at 12:11 UTC due to a leak of Liquid Hydrogen at the Ground Umbilical Carrier Plate (GUCP) detected during the tanking process. Leaks at the GUCP delayed launches for STS-119 and STS-127.

The teams are working a 48 hours turnaround 72 hours turnaround with launch targeted at 18:15:46 UTC on Sunday, as 24 hours is not enough to drain the External Tank (ET) to examine and resolved the issue. The current launch window closes on Sunday, November 7, 2010. The shuttle cannot launch between Nov. 8 and Nov. 23 because of a so-called beta angle cutout. Such cutouts are defined by the angle between the sun and the plane of the space station’s orbit. When it the beta angle is too high or too low, temperature constraints for the docked shuttle-station stack can exceed safety guidelines. Nevertheless, the Mission Management Team (MMT) is also looking into the possibility to launch on Monday, Nov 8 with a reworked flight plan.

Did Physicists Find Evidence of a Fourth Neutrino Flavor? – When neutrinos change from one phase to another, they tell us something about their mysterious nature. These ghostly subatomic particles come in three flavors, physicists say: muon, tau, and electron. Just this summer, a team caught a neutrino in the act of changing from muon to tau, a finding that backed up the argument that these particles do, in fact, have mass. This week, a new study of neutrino oscillation—the changing of flavors—suggests an deeper mystery, and implies that these three flavors of neutrino may not be enough to account these particles’ behavior. -Discovery Magazine Blogs

Night Lights

Constellations of lights sprawl across this night scene, but they don't belong in the skies of planet Earth. Instead, the view looks down from the International Space Station as it passed over the United States along the northern Gulf Coast on October 29. A Russian Soyuz spacecraft is docked in the foreground. Behind its extended solar panels, some 360 kilometers below, are the recognizable city lights of New Orleans. Looking east along the coast to the top of the frame finds Mobile, Alabama while Houston city lights stand out to the west, toward the bottom. North (left) of New Orleans, a line of lights tracing central US highway I55 connect to Jackson, Mississippi and Memphis, Tennessee. Of course, the lights follow the population centers, but not everyone lives on planet Earth all the time these days. November 2nd marked the first decade of continuous human presence in space on board the International Space Station. - Credit: ISS Expedition 25, NASA
