HERA (Hydrogen Epoch of Reionization Array)

HERA (Hydrogen Epoch of Reionization Array) is a specialized radio telescope designed to study the early universe, specifically the period called the Epoch of Reionization, roughly 13 billion years ago. During this time, the first stars and galaxies formed, transforming the universe from darkness into a light-filled cosmos. HERA detects faint radio signals emitted by hydrogen atoms in that era, helping scientists understand how the first structures evolved. Its array of antennas collects this data to uncover the mysteries of the universe’s infancy, enhancing our knowledge of cosmic history and evolution.
