Square Kilometer Array (SKA)

The Square Kilometer Array (SKA) is a next-generation radio telescope that will be the world's largest and most sensitive radio telescope. It will be built in two phases, with the first phase, SKA1, being completed in the early 2020s and the second phase, SKA2, being completed in the late 2020s. The SKA will be used to study a wide range of astronomical phenomena, including the formation and evolution of galaxies, the nature of dark matter and dark energy, and the search for extraterrestrial life.
