The Wilkinson Microwave Anisotropy Probe (WMAP), originally known as the Microwave Anisotropy Probe (MAP) was a spacecraft operating from 2001 to 2010 which measured differences across the sky in the temperature of the cosmic microwave background (CMB) … The WMAP mission reveals the conditions of the early universe by measuring the comic microwave background radiation in the sky. The Wilkinson Microwave Anisotropy Probe (WMAP) is a Medium-Class Explorer (MIDEX) satellite aimed at elucidating cosmology through full-sky observations of the cosmic microwave background (CMB). 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. Wilkinson Microwave Anisotropy Probe (WMAP) — denumită și Explorer 80 — este o navă spațială ce măsoară diferențele de temperatură ale radiațiilor remanente ale Big Bangului — radiația cosmică de fond — pe tot cerul.
