Figure 1. Cosmic Microwave Background and Clouds Compared:(a) Early in the universe, photons (electromagnetic energy) were scattering off the crowded, hot, charged particles and could not get very far without colliding with another particle. But after electrons and photons settled into neutral atom...

The cosmic microwave background (CMB) is leftover radiation from theBig Bangor the time when the universe began. As the theory goes, when the universe was born it underwent rapid inflation, expansion and cooling. (The universe is still expanding today, andthe expansion rate appears different de...
WMAP data of the Cosmic Microwave Background. Credit: NASA Haters are going to argue that we will never know what the true shape of our Universe is. Those people are no fun, and are just obstructionists. Seriously, let us help you get better friends. ...
Email Temperature fluctuations in the cosmic microwave background from nine years of observations using the Wilkinson Microwave Anisotropy Probe (WMAP).© NASA Modifying the standard model of cosmology to allow for a curved universe could help ease confusion between cosmologists who calculate different ...
The blackbody radiation inversion (BRI), as discussed in “Method and validation” section, is applied to the cosmic microwave background radiation for obtaining the temperature of the universe and the probability distribution of temperature. We have used the data of COBE FIRAS to calculate intensity...
