The Wilkinson Microwave Anisotropy Probe (WMAP), originally known as the Microwave Anisotropy Probe (MAP and Explorer 80), was a NASA spacecraft operating from 2001 to 2010 which measured temperature differences across the sky in the cosmic microwave background (CMB) – the radiant heat remaining from the Big Bang.

Dec 20, 2012 · The Wilkinson Microwave Anisotropy Probe (WMAP) is a NASA Explorer mission that launched June 2001 to make fundamental measurements of cosmology -- the study of the properties of our universe as a whole.

Dec 21, 2012 · Public access site for The Wilkinson Microwave Anisotropy Probe and associated information about cosmology.

The WMAP (Wilkinson Microwave Anisotropy Probe) mission is designed to determine the geometry, content, and evolution of the universe via a 13 arcminute FWHM resolution full sky map of the temperature anisotropy of the cosmic microwave background radiation.

Sep 8, 2010 · Wilkinson Microwave Anisotropy Probe (WMAP), a U.S. satellite launched in 2001 that mapped irregularities in the cosmic microwave background (CMB). The CMB was discovered in 1964 when German American physicist Arno Penzias and American astronomer Robert Wilson determined that noise in a microwave

The WMAP science team has conducted detailed studies on the temperature and polarization of the Cosmic Microwave Background (CMB), achieving remarkable accuracy and precision. Through these studies, WMAP has unveiled significant aspects …

We perform an independent foreground analysis of the WMAP maps to produce a cleaned CMB map (available online) useful for cross-correlation with, e.g., galaxy and X-ray maps.

Dec 20, 2012 · We provide new nine-year full sky temperature maps that were processed to reduce the asymmetry of the effective beams. Temperature and polarization sky maps are examined to separate CMB anisotropy from foreground emission, and both types of signals are analyzed in detail.

The CMB Cold Spot or WMAP Cold Spot is a region of the sky seen in microwaves that has been found to be unusually large and cold relative to the expected properties of the cosmic microwave background radiation (CMBR).

Apr 10, 2024 · The detailed, all-sky picture of the infant universe created from nine years of WMAP data. The image reveals 13.77 billion year old temperature fluctuations (shown as color differences) that correspond to the seeds that grew to become the galaxies.
