Keck Array

The Keck Array is a scientific instrument designed to study the universe’s earliest moments by detecting faint microwave signals from the Cosmic Microwave Background (CMB). It consists of multiple telescopes located at the South Pole, focusing on measuring tiny temperature fluctuations in this ancient radiation. These measurements help scientists understand the universe’s origin, composition, and evolution, including clues about cosmic inflation and gravitational waves. The Keck Array’s highly sensitive detectors and strategic location enable it to gather precise data, contributing valuable insights into fundamental questions about the cosmos.
