Four Centuries of Discovery

David Spergel’s Telescope


Wilkinson Microwave Anistropy Probe


The Wilkinson Microwave Anisotropy Probe (WMAP) launched in 2001 to make fundamental measurements of cosmology—the study of the properties of our universe as a whole. WMAP has been stunningly successful, producing unprecedented fine-resolution maps of the cosmic microwave background—a faint background glow that fills the universe and is evidence for the Big Bang.
