Experiment to Detect the Global EoR Signature, Radio telescope at Murchison Radio-astronomy Observatory, Western Australia
The Experiment to Detect the Global EoR Signature is a specialized radio telescope with antennas designed to capture signals between 50 and 200 megahertz. The equipment sits at the Murchison Radio-astronomy Observatory in a remote part of Western Australia.
The equipment began operating in August 2015, starting a new chapter in studying the earliest periods of cosmic development. Since then it has continuously searched for evidence of how the first structures in the universe formed.
The site brings together researchers from multiple countries who work on questions about how the universe began to take shape. This international effort shows how scientists collaborate across borders to solve some of astronomy's biggest puzzles.
The remote setting shields the telescope from interference caused by human activity and allows for clean measurements. Visitors should know that the equipment is located in a very isolated area that requires proper planning before a visit.
In March 2018, the telescope detected an absorption pattern at 78 megahertz that revealed new clues about how the first stars formed. This discovery demonstrated that the instrument could actually capture signals from the very distant cosmic past.
