Astronomers have pushed NASA’s Hubble Space Telescope to its limits by finding what they believe is the most distant, ancient object ever seen in the universe. Its light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is 13.7 billion years. The dim object is a tiny, compact galaxy of blue stars that existed 480 million years after the big bang, only four percent of the universe’s current age. It is so small, more than one hundred similarly-sized mini-galaxies would be needed to make up our Milky Way.

NASA’S Mission Control and ISS Crew Observe National Moment of Silence
At Mission Control at the Johnson Space Center in Houston and aboard the International Space Station, flight controllers and the Expedition 26 crew paused to observe a National Moment of Silence Jan. 10, 2011. The event was held for the victims of the shootings in Tucson, Ariz., Jan. 8 that left six people dead and more than a dozen wounded, including Rep. Gabrielle Giffords (D-AZ). Station Commander Scott Kelly, Giffords’ brother-in-law, led the station crew in its observance from 220 miles above the Earth.

NASA’s Kepler Spacecraft Discovers Its First Rocky Exoplanet
NASA’s Kepler spacecraft has discovered Kepler-10b, its first confirmed rocky planet and the smallest transiting exoplanet discovered to date. Kepler-10b is only 1.4 times the size of Earth and has an average density of 8.8 grams per cubic centimeter, similar to that of an iron dumbbell. The planet orbits its star in only 0.84 days and is not in the habitable zone, where liquid water could exist.

NASA Science Seminar “Arsenic and the Meaning of Life”
A scientific presentation by U.S. Geological Survey research hydrologist Dr. Ronald Oremland about the role of arsenic in microbial life and the microbial ecology of California’s Mono Lake.
Oremland is a senior scientist with the USGS Water Resources Division in Menlo Park, Calif., and a principal investigator with NASA’s Exobiology and Evolutionary Biology Program, an element of NASA’s Astrobiology Program. He is a co-author of the paper on arsenic findings published last week in Science Express and announced during the Dec. 2 NASA press conference. -
NASA-Funded Research Discovers Life Built with Toxic Chemical
NASA-funded astrobiology research has changed the fundamental knowledge about what comprises all known life on Earth.
Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic for phosphorus in its cell components.
This finding of an alternative biochemistry makeup will alter biology textbooks
and expand the scope of the search for life beyond Earth. The research
is published in this week’s edition of Science Express. -
Space Station Crew Uses HAM Radio to Call Earth
Inside the International Space Station, Expedition 25 commander Doug Wheelock gave a tour of the Russian segment of the orbiting complex, including the Soyuz spacecraft docked there. Wheelock showed off the station’s HAM radio, using the call sign “NA1SS,” to talk with people on the ground as the station flies overhead at 17,500 miles per hour. Wheelock, and Flight Engineers Shannon Walker and Fyodor Yurchickin all will return home to Earth this Thursday, Nov. 25.

First “Goldilocks” Exoplanet Discovered by NASA-funded Researchers
A team of planet hunters led by astronomers at the University of California (UC), Santa Cruz and the Carnegie Institution of Washington has announced the discovery of a planet orbiting a nearby star, Gliese 581, at a distance that places it squarely in the middle of the star’s “habitable zone.” This would be the most Earth-like exoplanet and the first truly habitable one yet discovered. The research was supported by grants from NASA and the National Science Foundation. “Goldilocks” refers to an exoplanet whose temperatures are “not too cold, not too hot, but just right” to maintain water and support Earth-like life.

Using LEGO® to simulate ESA’s touchdown on a comet
Comets are primeval leftovers from the origins of the Solar System. To fully understand these ancient objects and perhaps the origins of life on Earth, ESA’s Rosetta mission will rendezvous with comet Churyumov-Gerasimenko in 2014. In November of that year, Rosetta’s Philae lander will touchdown on the comet and thoroughly investigate its composition.

ESA Space Scientist Detlef Koschny explains why he originally built Rosetta in LEGO®
Space missions are complicated pieces of orbital choreography. When planning a mission, spacecraft engineers must calculate how to point the solar panels towards the Sun, the main antenna towards Earth and the instruments towards the target. ESA Space Scientist Detlef Koschny build a LEGO model of Rosetta mission in order to visualise these precise orientations.

U2 in Space and On Tour with NASA
A year’s worth of collaboration between NASA and U2 both in space and on the Irish rock band’s “360” world tour is highlighted in a new video produced by the group. In 2009, U2 approached NASA with the idea to include the crew of the International Space Station in its shows, and the astronauts agreed to participate in this unique experience. Bono, The Edge, Adam Clayton and Larry Mullen, Jr. spoke with the Expedition 20 crew on the space station several times before the astronauts recorded a video segment that U2 incorporated into its concerts. The crew members include Michael Barratt of NASA, Frank De Winne of the European Space Agency, Bob Thirsk of the Canadian Space Agency, Koichi Wakata of the Japan Aerospace Exploration Agency, and Gennady Padalka and Roman Romanenko of the Russian Federal Space Agency.
