Europe's billion-dollar Planck space telescope brought results on Tuesday that have delighted astronomers as it showed off 15,000 new celestial objects. Astronomers reported at a conference in Paris that Planck has carried out three complete scans of the Universe, showing off 15,000 new celestial objects, including 30 galaxy clusters. Jan Tauber, a project scientist at the European Space Agency (ESA), said that the data is a "treasure trove" that will be exploited for years to come. "For...

VENTURA, Calif. and HERCULES, Calif., Dec. 20, 2010 /PRNewswire-USNewswire/ -- Coastal Marine Biolabs (CMB), a recognized leader in its ongoing efforts to engage students in DNA barcoding, and Bio-Rad Laboratories, Inc., a multinational manufacturer and distributor of life science research and clinical diagnostics products, today announced a collaboration to co-develop DNA barcoding instructional activities for the classroom. The collaboration merges Bio-Rad's expertise in the development...

Astronomers have traced the waxing and waning light of exploding stars more closely than ever before and seen patterns that aren't yet accounted for in our current understanding of how these eruptions occur. Using data from a sensitive instrument aboard a satellite that images the entire sky every 102 minutes, they studied four of these stars, or novae, that exploded so violently their light would have been visible without a telescope and measured their brightness over the course of the...

Search for ultra high energy neutrinos from space turns the moon into part of the 'detector' Seeking to detect mysterious, ultra-high-energy neutrinos from distant regions of space, a team of astronomers used the Moon as part of an innovative telescope system for the search. Their work gave new insight on the possible origin of the elusive subatomic particles and points the way to opening a new view of the Universe in the future. The team used special-purpose electronic equipment brought to...

Study from Chadwick Martin Bailey finds increased cloud computing adoption, but concerns around security and cost remain Boston, MA (Vocus/PRWEB) November 18, 2010 A recent Chadwick Martin Bailey (CMB) Tech Pulse study found that there is less confusion around the term "cloud computing" and adoption plans have increased over the last 12 months. In early 2009 a similar CMB Tech Pulse study found only 15% said their organization had aggressive plans to migrate towards cloud computing...

As scientists and engineers work to make NASA's James Webb Space Telescope a reality, they find themselves wondering what new sights the largest space-based observatory ever constructed will reveal. With Webb, astronomers aim to catch planets in the making and identify the universe's first stars and galaxies, yet these are things no telescope -- not even Hubble -- has ever shown them before. "It's an interesting problem," said Jonathan Gardner, the project's deputy senior project scientist...

Team uses observations from powerful radio telescope in high Andean desert; results will help scientists understand how universe is evolving An international team of scientists led by Rutgers University astrophysicists have discovered 10 new massive galaxy clusters from a large, uniform survey of the southern sky. The survey was conducted using a breakthrough technique that detects "shadows" of galaxy clusters on the cosmic microwave background radiation, a relic of the "big bang" that gave...

Astronomers using the South Pole Telescope report that they have discovered the most massive galaxy cluster yet seen at a distance of 7 billion light-years. The cluster (designated SPT-CL J0546-5345) weighs in at around 800 trillion Suns, and holds hundreds of galaxies. "This galaxy cluster wins the heavyweight title. It's among the most massive clusters ever found at this distance," said Mark Brodwin, a Smithsonian astronomer at the Harvard-Smithsonian Center for Astrophysics. Brodwin is...

After nine years of scanning the sky, the Wilkinson Microwave Anisotropy Probe (WMAP) space mission has concluded its observations of the cosmic microwave background, the oldest light in the universe. The spacecraft has not only given scientists their best look at this remnant glow, but also established the scientific model that describes the history and structure of the universe. "WMAP has opened a window into the earliest universe that we could scarcely imagine a generation ago," said Gary...

Surveying the microwave sky, Planck has obtained its very first images of galaxy clusters, amongst the largest objects in the Universe, by means of the Sunyaev-Zel'dovich effect, a characteristic signature they imprint on the Cosmic Microwave Background. Joining forces in a fruitful collaboration between ESA missions, XMM-Newton followed up Planck's detections and revealed that one of them is a previously unknown supercluster of galaxies. Matter in the Universe is distributed in a highly...

Yakov Borisovich Zel'dovich (March 8, 1914 "“ December 2, 1987) was a productive Soviet physicist. He was instrumental in the advancement of Soviet nuclear and thermonuclear weapons, and also was an invaluable assistance in the fields of adsorption and catalysis, shock waves, nuclear physics, particle physics, astrophysics, physical cosmology, and general relativity. In 1914, he was born into a Jewish family in Minsk, now called Belarus. Four months after his birth, he and his family...

Cosmology -- area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe. Modern Cosmological Theories Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation. Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point...

Cosmic Background Radiation -- The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the cosmic microwave background radiation, or CMB. When any patch of the sky is observed where no individual sources can be discerned, and the effects of the interplanetary dust, and interstellar matter are taken into...

Wilkinson Microwave Anisotropy Probe (WMAP) -- The Wilkinson Microwave Anisotropy Probe (WMAP) was launched on June 30, 2001 at 3:46 p.m. EDT at Cape Canaveral Air Force Station, Florida, USA. The goal of WMAP was to map out minute differences in the Cosmic Microwave Background (CMB) radiation which would help test theories of the nature of the universe. On February 11, 2003, the public relations group from NASA made a press release regarding the age and composition of the universe....
