The Hermanus Astronomy Centre’s (“HAC”) visit to SKA’s Meerkat site included the HERA facility. HERA is an array of 133 antennae measuring 14 meters in diameter. It was designed to detect radio waves in the low-frequency range of 100-200 MHz, which allows it to detect fluctuations in the emissions from neutral hydrogen in the Epoch of Re-ionisation before the first stars, galaxies and black holes were formed. This will allow astronomers to understand the formation and evolution of these very first luminous sources.
