Both maps are foreground-cleaned, WMAP by subtracting a linear least squares fit to the Planck dust and low-frequency templates.

The satellite, which single-handedly helped establish the standard model of cosmology, took its last look at the cosmos Aug. 20, and settled into a final parking orbit around the sun Sept. 8.

The Wilkinson Microwave Anisotropy Probe (WMAP), originally known as the Microwave Anisotropy Probe (MAP), was a 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. The properties of the radiation contain a wealth of information about physical conditions in the early universe and a great deal of effort has gone into measuring … WMAP observations also support an add-on to the big bang framework to account for the earliest moments of the universe. Headed by Professor Charles L. Bennett of Johns Hopkins University, the mission was … 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.

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. The output of each assembly is proportional to the temperature (brightness) difference between the two lines of sight on the sky. WMAP - PLANCK All Sky Comparison The top image is the WMAP 9 year W-band CMB map and the bottom image is the Planck SMICA CMB map.

Planck has also measured this radiation and its fluctuations in more frequency bands (nine in total) than any satellite that came before.

Among other revelations, the data from WMAP revealed a much more precise estimate for the age of the universe — 13.7 billion years — and confirmed … The WMAP mission succeeded the COBE space mission and was the second medium-class (MIDEX) spacecraft in the NASA Explorers program. In 2003, MAP was renamed WMAP in honor of cosmologist David Todd Wilkinson (1935–2002), who had been a member of the mission's science team. Both maps are foreground-cleaned, WMAP by subtracting a linear least squares fit to the Planck dust and low-frequency templates. All of the matter between Earth and the edge of the observable universe is shown in this image based on data from the European Space Agency's Planck space observatory. Public access site for The Wilkinson Microwave Anisotropy Probe and associated information about cosmology. The NASA WMAP mission (2001-2010) and the ESA Planck mission (2009-2013) continued the legacy of COBE, studying the cosmic microwave background in ever greater detail. The cosmic microwave background (CMB) radiation is the radiant heat left over from the Big Bang.It was first observed in 1965 by Arno Penzias and Robert Wilson at the Bell Telephone Laboratories in Murray Hill, New Jersey. + See More

The cosmic microwave background is the afterglow radiation left over from the hot Big Bang.

The WMAP spacecraft was launched on June 30, 2001 from Florida. The top image is the WMAP 9 year W-band CMB map and the bottom image is the Planck SMICA CMB map.

COBE Images. Detailed, all-sky picture of the infant universe from seven years of WMAP data.

Features of this site include: sectoring, animation of global images and at high resolution for a region of interest.
However, tiny temperature variations or fluctuations (at the part per million level) can offer great insight into the origin, evolution, and content of … Please acknowledge the WMAP Science Team when using these images. WMAP Mission Overview. The COBE slide set contains high-resolution all COBE digital images. The Wilkinson Microwave Anisotropy Probe (WMAP) mission reveals conditions as they existed in the early universe by measuring the properties of the cosmic microwave background radiation over the full sky. ; The FIRAS images depict data taken with the COBE FIRAS instrument. Interactively zoom and animate weather satellite images from a variety of geostationary satellites. About a decade ago, WMAP …
