CMB Anisotropy Project
Mapping the afterglow of the Big Bang to decode the origins of the universe.
The CMB Anisotropy Project is dedicated to the high-precision analysis of the Cosmic Microwave Background (CMB), the faint afterglow of the Big Bang. We map and study the minute temperature variations, or anisotropies, in this ancient light to probe the conditions of the infant universe. These patterns hold the secrets to cosmic inflation, the distribution of dark matter and dark energy, and the fundamental parameters that define our universe. Our work involves processing vast datasets from space-based observatories to create the most detailed maps of the early cosmos ever produced.

FAQs about CMB Anisotropy Project
The CMB is the oldest light in the universe. It's a faint afterglow of heat leftover from the Big Bang that fills all of space.
In this context, an anisotropy is a very small difference in temperature in the CMB. While the CMB is incredibly uniform, it has tiny hot and cold spots.
These tiny temperature spots were the seeds that grew into everything we see today. The slightly denser, hotter spots eventually formed all the stars, planets, and galaxies through gravity. 🌌
The project uses very sensitive radio telescopes, often located in high-altitude, dry locations like the Atacama Desert or on space satellites, to create detailed maps of these faint temperature patterns across the entire sky.
