Hydrogen Epoch of Reionization Array
Hydrogen Epoch of Reionization Array, Radio telescope facility in Karoo region, South Africa
The Hydrogen Epoch of Reionization Array contains 331 fixed antennas arranged in a hexagonal pattern, each measuring 14 meters in diameter.
This telescope emerged from earlier projects including the Precision Array for Probing the Epoch of Reionization, advancing research capabilities in cosmic observation.
Scientists from South Africa, United States, and United Kingdom collaborate at HERA to study the formation period of first stars and galaxies.
The facility operates during night hours in the frequency range of 100-200 MHz to minimize interference from solar emissions and terrestrial signals.
The array measures hydrogen power spectrum fluctuations from the early universe through 54,000 square meters of collecting surface using cost-effective materials.
