In what wavelength range do we detect the cmb
WebWien's blackbody law says that the wavelength peak of the CMB spectrum is inversely proportional to the temperature of the CMB. Therefore, the drop in the CMB temperature … WebThe CMB is a snapshot of the oldest light in our universe, imprinted on the sky when the universe was just about 380,000 years old. The first spacecraft, launched in 1989, is NASA’s Cosmic Background Explorer, or COBE. WMAP was launched in 2001, and Planck was launched in 2009.
