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

Aboard the International Space Station, Expedition 25 Flight Engineer Shannon Walker discussed her life and work in orbit with renowned astrophysicist Dr. Neil deGrasse Tyson during an in-flight interview Nov. 22 for his syndicated StarTalk radio program. Walker will return to Earth Thanksgiving Day with Soyuz Commander Fyodor Yurchikhin and station Commander Doug Wheelock in their Soyuz TMA-19 spacecraft for a landing on the steppe of Kazakhstan after 5 and half months in space.

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.
