Wilkinson Microwave Anisotropy Probe (WMAP) Mission (Liz Citrin)

WIRE The Wide-field Infrared Explorer (WIRE) was a small satellite carrying a cryogenically cooled infrared telescope designed to study starburst galaxies—vast clouds of molecular gas cradling the sites of newborn stars. Developed under NASA's Small Explorer Program, WIRE was intended to have a four month primary mission. WIRE was launched on a three-stage Pegasus XL vehicle released from an L-1011 aircraft over the Pacific Ocean after takeoff from California's Vandenberg Air Force Base on March 4, 1999. The satellite was successfully placed in orbit around Earth at an altitude of 540 kilometers (about 335 miles). The mission failed soon after launch when the cover on the telescope/cryostat ejected prematurely. Uncontrolled heating of the cryostat caused the solid hydrogen cryogen to be expelled and resulted in the satellite spinning out of control. Flight controllers ultimately regained control of the satellite, but the primary science objectives were lost, as the infrared detectors could not be cooled.

Journey To The Big Bang From WMAP

Take a trip through space and time to put "earliest light" in perspective. Pulling back from the WMAP spacecraft in orbit at L2, we see that we are but a tiny speck in our Milky Way Galaxy. As the journey continues, we see that the Milky Way is but a tiny speck in the Universe as we pass quasars that were some of the early brightest structures that we can detect with conventional instruments. Finally we arrive at the beginning of time as we understand it. The super heated, roiling ionized hydrogen gas of a universe newly made glows throughout the universe. The energy from sonically condensed and rarified ripples in this gas, released as it cooled to 3000° kelvin, is the basis for the data collected by WMAP. credit: NASA / WMAP Science Team source: map.gsfc.nasa.gov

Big Bang for the Buck: Cosmology from WMAP

Charles L. Bennett is the Alumni Centennial Professor of Physics and Astronomy at Johns Hopkins University in Baltimore. He does research in cosmology, the study of the large scale properties of the universe. He was among the leaders of the Cosmic Background Explorer (COBE) mission and he led the Wilkinson Microwave Anisotropy Probe space mission. The Wilkinson Microwave Anisotropy (WMAP) Explorer space mission mapped the remnant radiation from the Big Bang across the entire sky. From the patterns observed, scientists have deduced the age, history, contents, and geometry of our universe. From dark matter to dark energy, to the first trillionth of a trillionth of a second of the universe, big things have come from this small mission. Dr. Bennett will answer: what has been discovered? What mysteries remain?

WMAP reionization

About 400000 years after the big bang, the intergalactic medium (IGM) composed of free protons and electrons. Photons could not move freely as the would collide with the active particles and scatter. The universe cooled down to approx. 3000k, the protons and electrons combined and the first hydrogen atoms were formed. This allowed light to travel in a straight path for the first time and over a period of 13 billion years, shifted to the microwave end of the spectrum. These first rays of light make up the Cosmic Microwave Background we pick up today. This image shows the process of the IGM collapsing into neutral atoms which then collapsed under gravity into denser regions, eventually forming the first stars and galaxies. This triggered the next phase called reionization. Approx. dimensions of box- 100 Mpc square (1 megaparsec = 3.2 million light years). The z figure indicates the red shift, 15=13.7 billion years, 6=13.4 billion years. More info regarding z and redshift- hyperphysics.phy-astr.gsu.edu

WMAP shape of the universe

According to data received from the WMAP (Wilkinson Microwave Anistropy Probe), the shape of the universe is 'flat' (as opposed to 'open' or 'closed') as the microwaves from the first light received are not distorted. If the universe is flat (and because luminous & dark matter only constitute 27% of the critical density) a dark energy is postulated to make up the remaining 73% of the critical density.
