 | Carnegie Mellon University joined the collaboration building the Large Synoptic Survey Telescope (LSST) and is now among the 23 universities, national laboratories and corporations involved in constructing the world's most powerful survey telescope. ...> Full Article |
 | Astronomers at Rutgers and Penn State universities have discovered galaxies in the distant universe that are ancestors of spiral galaxies like our Milky Way. ...> Full Article |
 | A team of scientists from the Naval Research Laboratory, the Air Force Research Laboratory's (AFRL's) Research Vehicles Directorate, Kirtland Air Force Base, N.M., and the University of New Mexico (UNM) has detected the lowest frequency radar echo from the moon ever seen with earth-based receivers. ...> Full Article |
 | Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin. After testing helium and neon trapped in the dust specks, Pepin and his colleagues report that while the comet formed in the icy fringes of the solar system, the dust appears to have been born close to the infant sun and bombarded by intense radiation from these and other gases before being flung out beyond Neptune and trapped in the comet. ...> Full Article |
New Mexico Tech's Magdalena Ridge Observatory (MRO) is already making its mark in the annals of astronomy research after being recently tasked by NASA to make detailed observations of an asteroid that is now given a 1 in 75 chance of hitting Mars on January 30, 2008.

 | A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM transactions, showed signs it was on its way late Thursday when the cycle's first sunspot appeared in the sun's Northern Hemisphere, NOAA scientists said. ...> Full Article |
 | MESSENGER's mid-December trajectory correction maneuver (TCM-19) went so well that the mission's design and navigation teams have decided that a TCM scheduled for January 10 will not be needed. ...> Full Article |
 | The first definitive evidence of cosmic dust, important in building planets like our Earth and ultimately ourselves, has been found in the remains of a massive star explosion 11,000 light years away in our own Galaxy. ...> Full Article |
 | After receiving its first fresh, full coat of paint in more than 40 years, Arecibo Observatory made its first observation in more than six months at 6:36 a.m., Saturday, Dec. 8. ...> Full Article |
 | Astronomers have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star. The eight-million-year-old star, known as HR 4796A, is inferred to be in the late stages of planet formation, suggesting that the basic building blocks of life may be common in planetary systems. ...> Full Article |
 | Saturn's chilly north pole boasts a hot spot in the middle of its mysterious polar hexagon, according to new data from the Cassini spacecraft. The discovery could shed light on the atmospheric formations found on other planets such as Jupiter, Neptune and Mars. ...> Full Article |
Celestial collision on Jan. 30 would be a bonanza for Earthlings, scientists say

 | Nestled high in the Andes Mountains of northern Chile, a rocky plot of ground will be the site for the world's largest telescope - one so powerful that it is expected to give perhaps the first definitive answer of whether or not there is life beyond Earth. ...> Full Article |
 | An international team of physicists, including University of Oregon scientists, has concluded that last February's intense burst of gamma rays possibly coming from the Andromeda Galaxy lacked a gravitational wave. That absence, they say, rules out an initial interpretation that the burst came from merging neutron stars or black holes within Andromeda. ...> Full Article |
 | An asteroid discovered by The University of Arizona's Catalina Sky Survey has a 4 percent chance of hitting Mars on Jan. 30, scientists say. ...> Full Article |
The Large Synoptic Survey Telescope (LSST) Project will announce today, Jan. 3, its receipt of two major gifts: $20 million from the Charles Simonyi Fund for Arts and Sciences and $10 million from Microsoft founder Bill Gates. "The LSST is an extremely ambitious project that will have enormous impact on a wide range of scientific questions," said Niel Brandt, Penn State professor of astronomy and the leader of the LSST ActiveGalaxy/Quasar team. "We are quite excited about the multitude of research opportunities -- ranging from potential killer asteroids in our solar system to the most distant objects in the universe -- that will be available for Penn State scientists."

 | Armchair astronomers using the galaxyzoo.org website have identified over 500 overlapping galaxies in the local Universe when astronomers had previously only known of 20 such systems. ...> Full Article |
 | New observations from Suzaku, a joint Japanese Aerospace Exploration Agency (JAXA) and NASA X-ray observatory, have challenged scientists' conventional understanding of white dwarfs. Observers had believed white dwarfs were inert stellar corpses that slowly cool and fade away, but the new data tell a completely different story. ...> Full Article |
 | A model of the James Webb Space Telescope's Mid-InfraRed Instrument is being tested at the Rutherford Appleton Laboratory in Oxfordshire, England to ensure the final instrument can see infrared light. ...> Full Article |
 | An international team of astronomers, led by Professor Svetlana Berdyugina of ETH Zurich's Institute of Astronomy, has for the first time ever been able to detect and monitor the visible light that is scattered in the atmosphere of an exoplanet. ...> Full Article |
 | NASA has outlined a plan to repair a faulty electrical connector on Space Shuttle Atlantis' external fuel tank. The repair could take several days or even weeks. The launch date for ESA's Columbus laboratory of 10 January 2008 is no longer feasible. ...> Full Article |
 | Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate. ...> Full Article |
 | By working in synergy with a ground-based telescope array, the joint Japanese Aerospace Exploration Agency (JAXA)/NASA Suzaku X-ray observatory is shedding new light on some of the most energetic objects in our galaxy, but objects that remain shrouded in mystery. ...> Full Article |
 | Astronomers have found the best evidence yet of matter spiraling outward from a young, still-forming star in fountain-like jets. Due to the spiral motion, the jets help the star to grow by drawing angular momentum from the surrounding accretion disk. ...> Full Article |
 | Using ESO's Very Large Telescope, an international team of astronomers has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed 'The Bird' - albeit it also bears resemblance with a cosmic Tinker Bell - is composed of two massive spiral galaxies and a third irregular galaxy. ...> Full Article |
NASA has selected Case Western Reserve University geophysicist Steven A. Hauck II as one of 23 "participating scientists" to join a team collecting and analyzing data from the MESSENGER mission to Mercury. MESSENGER, an autonomous spacecraft, is expected to reach the innermost planet in January.

 | By analyzing images from NASA's Cassini Radar instrument, a Brigham Young University professor helped discover and analyze mountains on Saturn's largest moon, additional evidence that it has some of the most earthlike processes of any celestial body in the solar system. ...> Full Article |
 | A team of astronomers at Penn State and Caltech has discovered a cosmic explosion that seems to have come from the middle of nowhere -- thousands of light-years from the nearest galaxy-sized collection of stars, gas and dust. This "shot in the dark" is surprising because the type of explosion, a long-duration gamma-ray burst (GRB), is thought to be powered by the death of a massive star. ...> Full Article |
 | ESA, NASA and an international team are developing plans and seeking recommendations to launch the first Mars mission to bring soil samples back to Earth. The ability to study soil from Mars here on Earth will contribute significantly to answering questions about the possibility of life on the Red Planet. ...> Full Article |
A scientist with The University of Arizona Lunar and Planetary Laboratory will discover more about comets and Earth's moon, thanks to spacecraft on extended and new NASA missions.
