Deep Synoptic Array
The Deep Synoptic Array (DSA) is a radio telescope array that will contain 1,650 steerable 6.15-metre (20 ft 2 in) parabolic antennas that observe the 0.7–2 GHz frequency range, scattered over an area of 19 by 15 kilometres (12 mi × 9 mi). The main goal is a radio survey of the entire sky visible from its site, to search for transient sources.
