Astronomers have taken a significant step forward in uncovering the mysteries of the cosmic dawn. A collection of 350 radio telescopes located in the Karoo desert of South Africa is rapidly advancing towards the detection of the 'cosmic dawn' - the period following the Big Bang when stars first lit
The HERA radio telescope, located in Karoo in South Africa, consists of 350 dishes pointed upward to detect radio waves from the early universe.
“Over the last couple of decades, teams from around the world have worked toward a first detection of radio waves from the cosmic dawn. While such a detection remains elusive, HERA’s results represent the most precise pursuit to date,” says Adrian Liu, an Assistant Professor at the Department of Physics and the Trottier Space Institute atThe array was already the most sensitive radio telescope in the world dedicated to exploring the cosmic dawn.
