Precision Array for Probing the Epoch of Reionization, Radio interferometer in Meerkat National Park, South Africa.
The Precision Array for Probing the Epoch of Reionization is a radio interferometer in the Karoo desert consisting of 64 individual antennas positioned across a wide area. These antennas work together to capture and amplify extremely faint radio signals from the distant universe.
Construction began in 2009 with an initial setup that expanded steadily over the following years. This gradual growth allowed scientists to progressively improve the instrument's ability to detect distant signals.
The name refers to a pivotal moment in cosmic history when the universe transformed. Visitors can observe how international research teams work together in this remote location to answer fundamental questions about the early universe.
The facility is located in a remote area, so visitors should plan extra time for travel and check access conditions in advance. The desert heat can be intense, so proper preparation is essential.
The instrument can detect hydrogen signals from an era just a few hundred million years after the Big Bang. These observations help astronomers understand how the first stars and galaxies transformed the early universe.
