The 2013 Gruber Cosmology Prize recognizes Viatcheslav Mukhanov and Alexei Starobinsky for their formative contributions to inflationary theory, an essential component for understanding the evolution and structure of the universe. According to the Prize citation, their theoretical work “changed our views on the origin of our universe and on the mechanism of its formation of structure.” Thanks to their contributions, scientists have provided a compelling...

Johns Hopkins University professor Charles L. Bennett and members of the Wilkinson Microwave Anisotropy Probe (WMAP) space mission that he led will receive the Gruber Foundation´s 2012 Cosmology Prize in Beijing, China tomorrow. Bennett and the 26-member WMAP team will share the $500,000 prize and are being recognized by the foundation for their transformative study of an ancient light dating back to the infant universe. So precise and accurate are the WMAP results that they form the...

Charles L. Bennett and the Wilkinson Microwave Anisotropy Probe (WMAP) team are the recipients of the 2012 Gruber Cosmology Prize. Their observations and analyses of ancient light have provided the unprecedentedly rigorous measurements of the age, content, geometry, and origin of the universe that now comprise the Standard Cosmological Model. The Prize citation further recognizes that the exquisite specificity of these results has helped transform cosmology itself from “appealing...

Theories of the primordial Universe predict the existence of knots in the fabric of space - known as cosmic textures - which could be identified by looking at light from the cosmic microwave background (CMB), the relic radiation left over from the Big Bang. Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) satellite, researchers from UCL, Imperial College London and the Perimeter Institute have performed the first search for textures on the full sky, finding no evidence...

Planck's HFI Completes Survey Of Early Universe

The High Frequency Instrument on ESA's Planck mission has completed its survey of the remnant light from the Big Bang. The sensor ran out of coolant on Saturday as expected, ending its ability to detect this faint energy. "Planck has been a wonderful mission; spacecraft and instruments have been performing outstandingly well, creating a treasure trove of scientific data for us to work with," said Jan Tauber, ESA's Planck Project Scientist. Less than half a million years after the...

Galactic Brightness Helps Build Precision Model Of The Universe

Berkeley Lab scientists and their Sloan Digital Sky Survey colleagues use galactic brightness to build a precision model of the cosmos Since 2000, the three Sloan Digital Sky Surveys (SDSS I, II, III) have surveyed well over a quarter of the night sky and produced the biggest color map of the universe in three dimensions ever. Now scientists at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) and their SDSS colleagues, working with DOE´s...

One trillion years from now, an alien astronomer in our galaxy will have a difficult time figuring out how the universe began. They won't have the evidence that we enjoy today. Edwin Hubble made the first observations in support of the Big Bang model. He showed that galaxies are rushing away from each other due to the universe's expansion. More recently, astronomers discovered a pervasive afterglow from the Big Bang, known as the cosmic microwave background, left over from the universe's...

New research by astronomers in the Physics Department at Durham University suggests that the conventional wisdom about the content of the Universe may be wrong. Graduate student Utane Sawangwit and Professor Tom Shanks looked at observations from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite to study the remnant heat from the Big Bang. The two scientists find evidence that the errors in its data may be much larger than previously thought, which in turn makes the standard model of...

A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist. The team has obtained extremely precise data about the early universe, using a telescope near the South Pole in the Antarctic. Their measurements of the cosmic microwave background - a faintly glowing relic of the hot, dense, young universe - provide further support for the standard cosmological model of the universe. The findings confirm the...

The European Space Agency says it has completed a two-week first light assessment of its Planck space observatory and found data quality to be excellent. Plank, a microwave observatory, is designed to study the early universe and will make two full sky surveys, the first of which is expected to be completed in six months, the ESA said. The spacecraft has a mission life expectancy of 15 months, with the data it provides expected to keep both cosmologists and astrophysicists busy for decades....


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
