10 Years of SOHO - (Dec. 1995 - Dec 2005) - Courtesy of SOHO consortium. SOHO is a project of international cooperation between ESA and NASA.

NASA's Stratospheric Observatory For Infrared Astronomy (or SOFIA) completed its first science flight on Dec. 1, demonstrating the airborne observatory's ability to make observations not possible from ground-based telescopes. Five more flights are planned over the coming months in the observatory's Short Science series.

Solar Observation Mission Celebrates 15 Years – On December 2, 1995, the Solar and Heliospheric Observatory or SOHO was launched into space from Cape Canaveral aboard an Atlas IIAS rocket. The joint ESA/NASA project began its work observing the sun at a time when the term “solar weather” was almost never used. –NASA

Another close asteroid flyby – Near Earth Asteroid 2010 XB, discovered by the Catalina Sky Survey at Mt. Lemmon on Dec 1, flew by at the altitude of ~52,460 km on Nov 30 (1820 UT) –Minor Planet Center

NASA Aids in Characterizing Super-Earth Atmosphere – A team of astronomers, including two NASA Sagan Fellows, has made the first characterizations of a super-Earth’s atmosphere, by using a ground-based telescope. A super-Earth is a planet up to three times the size of Earth and weighing up to 10 times as much. The findings, reported in the Dec. 2 issue of the journal Nature, are a significant milestone toward eventually being able to probe the atmospheres of Earth-like planets for signs of life. –NASA / JPL

Red Dwarf Discovery Changes Everything! – Its often said that the number of grains of sand on Earth equals the number of stars in the Universe. Well it looks like a recent study by astronomers working at the Keck Observatory in Hawaii have found that its more like three times the number of grains of sand on Earth! Working with some of the most sophisticated equipment available, astronomers from Yale University have been counting the number of dim red dwarf stars in nearby galaxies which has led to a dramatic rethink of the number of stars in the Universe. -Mark Thompson / Universe Today

Secret Mini Space Shuttle Could Land on Friday – The US Air Force announced that the X-37B Orbital Test Vehicle, a miniature, unmanned space shuttle could return to Earth as soon as this Friday, December 3. It has been in Earth orbit for about nine months on a classified mission for the military. It will land at Vandenberg Air Force Base in Los Angeles sometime between Friday and Monday, Air Force officials said in a statement. –Nancy Atkinson / Universe Today

What’s up in the solar system in December 2010 – The year is racing to a close — I can’t believe December is here already! This month will see Japan’s Akatsuki join Venus Express at Venus; that happens on December 6 at 23:49 UT (December 7, Japan time). Cassini will perform a second of a pair of 50-kilometer Enceladus flybys (the first happened early today). Opportunity should, if she keeps up her current pace, arrive within spitting distance of Santa Maria crater. And, closer to home, there’ll be a total lunar eclipse over the night of December 20-21. –Emily Lakdawalla / Planetary Society

CitizenSky’s V-Star Team needs your help – The VStar team has done some amazing work in the last year. But they need more help. Read on for an update and how you may be able to contribute. –Citizen Sky

NASA Offers Space Shuttle Tiles To Schools And Universities – As the Space Shuttle Program nears retirement, NASA is looking for ways to preserve the program’s history and inspire the next generation of space explorers, scientists and engineers. Beginning Wednesday, NASA is offering 7,000 shuttle heat shield tiles to schools and universities that want to share technology and a piece of space history with their students. –NASA

Celestron’s Capture the Universe 2010 Astrophoto winners! – Last month, Discover Magazine and Celestron telescopes partnered for the second annual Capture the Universe astrophotography contest. Astronomers submitted about a hundred images made using Celestron optics for the contest, and I was chosen to pick my favorite two; a third was picked as Viewers’ Choice by the members of the Celestron website. All of the photos submitted are available at the CelestronImages site. –Phil Plait / Bad Astronomy

Announcement of Opportunity for ExoMars Entry, Descent and Landing Demonstrator Module Science – ESA and NASA have today issued an announcement of opportunity for scientific investigations on the 2016 ExoMars Entry, Descent and Landing Demonstrator Module (EDM) –ESA

Dutch astronomer instrumental in the founding of ESO has passed away – Professor Adriaan Blaauw, the European Southern Observatory’s second Director General, and a key figure in ESO’s early history, died yesterday, 1 December 2010, at the age of 96. –ESO

Flying to the Moon – From the Space Station? – Last month the International Space Station partner agencies met to discuss the continuation of space station operations into the next decade and its use as a research laboratory. They also did a little forward thinking, and talked about some unique possibilities for the station’s future, including the potential for using the space station as a launching point to fly a manned mission around the Moon. –Nancy AtkinsonUniverse Today

NASA Administrator Thanks President Obama and Congress for Agency’s New Direction Support – The following is a statement from NASA Administrator Charles Bolden in support of President Obama’s signing of the National Aeronautics and Space Administration Authorization Act of 2010 on Monday, Oct. 11, 2010 … –NASA

Solar storms coming our way this week? – The Sun is getting back into the swing of things: a big active region on its limb erupted yesterday (October 10), sending out a small storm of subatomic particles into space. We weren’t in the line of fire, but over the next few days the rotation of the Sun will bring Active Region 11112 closer to the center of the Sun’s disk, and if that region erupts it may send a storm our way. –Phil Plait / Bad Astronomy
