The Sagittarius Window Eclipsing Extrasolar Planet Search, or SWEEPS, was a 2006 astronomical survey project using the Hubble Space Telescope's Advanced Camera for Surveys - Wide Field Channel to monitor 180,000 stars for seven days to detect extrasolar planets via the transit method.〔 〕 ==Area examined==
The stars that were monitored in this astronomical survey were all located in the Sagittarius-I Window,〔 a rare transparent view to the Milky Way's central bulge stars in the Sagittarius constellation as our view to most of the galaxy's central stars is blocked by lanes of dust.〔 〕 These stars in the galaxy's central bulge region are approximately 27,000 light years from Earth.〔 〕
