The scientists were awarded the prize "for their discovery of the blackbody form and anisotropy of the cosmic microwave background radiation," the Royal Swedish Academy of Sciences in Stockholm said. Their work was based on measurements that were done with the help of the NASA-launched COBE satellite in 1989. (Sydney Morning Herald -- World)

Astronomers Trace The Evolution Of The First Galaxies In The Universe Sep 14, 2006
But the seeds of those first galaxies can be seen in the the cosmic microwave background radiation, measured most recently and accurately by the Wilkinson Microwave Anisotropy Probe (WMAP), which shows slight fluctuations of density in a remarkably homogeneous universe about 400,000 years after the Big Bang. "Very early in the evolution of the universe, everything was very smooth. But over time the universe became more and more clumpy as gravity pulled more matter into the denser areas," Bouwens...

Big Bang's Afterglow Fails Intergalactic 'Shadow' Test Sep 6, 2006
A team of UAH scientists led by Dr. Richard Lieu, a professor of physics, used data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) to scan the cosmic microwave background for shadows caused by 31 clusters of galaxies ... (June 13, 2001) -- The Microwave Anisotropy Probe (MAP), scheduled for launch June 30, will journey into deep space on a voyage to explore some of the deepest mysteries of the cosmos. (Science Daily)
What are dark matter and dark energy, and how are they affecting the universe? Aug 28, 2006
Recently, NASAs Wilkinson Microwave Anisotropy Probe (WMAP) satellite made precision measurements of the imprint of sound waves on the cosmic microwave background, produced some 400,000 years after the big bang. Because sound propagation depends on the properties of the medium--as anyone who has played with a helium balloon knows--the pattern of the sound waves viewed by WMAP is an indicator of the abundance of hydrogen and helium in the universe.

Lyman, along with his late mentor David Wilkinson, were also the leading proponents of the Wilkinson Microwave Anisotropy Probe (WMAP), a satellite orbiting the sun that could measure variations in microwave intensity with even greater precision than before. Physics department chair Daniel Marlow regards Page's selection as an honor well-deserved. (The Daily Princetonian, NJ)

Similarly, post-perovskite can also explain why shear waves travel at different speeds within the D" region depending on their direction, a phenomenon known as seismic anisotropy. The atomic orientation of post-perovskite permits these waves to travel more quickly along certain crystallographic axes than others giving rise to a pattern of anisotropy that can account for seismic observations in the D9 region.Deep questionsSuch atomic-level studies illuminate bigger questions in Earth science such...

Baby Universe Apr 14, 2006
The Wilkinson Microwave Anisotropy Probe (WMAP) satellite, launched in 2001 and now a million miles from Earth in the direction opposite the sun, has been measuring minute temperature fluctuations in the afterglow for three years. In 2003, the temperature fluctuations it had recorded had produced a very detailed picture of the early universe and allowed scientists to get answers to questions about the age of the universe, its composition and how it developed.

Before the Big Bang| Mar 21, 2006
The latest data from NASA's Wilkinson Microwave Anisotropy Probe is based on three years of continuous observations of the cosmic microwave background (CMB), the afterglow light produced when the universe was less than a million years old. WMAP polarization data allowed scientists to discriminate between competing models of inflation for the first time, NASA said in a statement. (iAfrica.com)

Evidence of universe's first instant Mar 18, 2006
The new evidence comes from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), a satellite designed to study the final whisper of the Big Bang - the primordial burst of energy widely held to have given birth to the universe. This whisper, actually low-level radiation, is known as the cosmic microwave background. (Christian Science Monitor)
NASA detects Big Bang afterglow Mar 18, 2006
The WMAP (Wilkinson Microwave Anisotropy Probe) mission detected light created in the early universe that has been travelling across the universe for more than 13 billion years, he said. Seen in the form of faint microwaves, this early light helped astronomers perceive tiny variations in what Bennett called "an otherwise astonishingly empty sea of nothingness" that was the baby universe.

Scientists find evidence supporting universe expansion Mar 17, 2006
From what they called "the most precise measurements of our infant universe" by the WMAP (Wilkinson Microwave Anisotropy Probe), scientists have found "new evidence that the universe suddenly grew from sub-microscopic to astronomical size in less than the blink of an eye," said physicist Charles Bennett of Johns Hopkins University, principal investigator for the WMAP spacecraft. "This tremendous inflation of the universe happened in much less than a trillionth of a second," he said at a... (Xinhua)

Oldest light shows universe grew fast, researchers say Mar 17, 2006
The results are based on readings from the Wilkinson Microwave Anisotropy Probe, a robotic instrument with two telescopes that sweeps the sky every six months in an orbit a million miles from Earth. Light from the probe also has confirmed a theory that the universe is made up mostly of dark energy, a mysterious force that continues to cause the universe's expansion, said Johns Hopkins astrophysicist Charles Bennett, the probe's principal investigator.

Using new data from a NASA satellite, scientists have the best evidence yet to support this scenario, known as "inflation." The evidence, from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite, was gathered during three years of continuous observations of remnant afterglow light -- cosmic background radiation that lingers, much cooled, from the universe's energetic beginnings 13. 7 billion years ago.
