TAROT-South robotic observatory

TAROT-South is an observatory equipped with two optical telescopes measuring 25 cm and 14 cm in diameter, located in the Coquimbo Region at an elevation of 2375 meters. The facility operates with fully automated systems designed to quickly detect and track sudden cosmic events across the night sky.

The observatory was established as part of the European Southern Observatory network at La Silla, which began operations in 1969. The rapid-response technology was developed later to meet the growing need to capture brief astronomical phenomena that fade within seconds.

Researchers from around the world work together at this facility to investigate sudden, fleeting cosmic events that require coordinated observation efforts. This international collaboration shows how modern astronomy brings scientists together to chase the most elusive phenomena in the sky.

The high elevation means visitors need time to acclimatize, so plan accordingly before arrival. The automated systems operate continuously, making clear skies and darkness essential for seeing the telescopes in action during observation sessions.

The facility can respond to satellite alerts and reposition its telescopes within seconds to observe newly detected cosmic events, a capability that sets it apart in astronomical research. This speed allows scientists to capture cosmic explosions before they fade from view.
