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.

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.

When a star that is much more massive than out sun gets to the end of it's like it explodes into a Super Nova. A Super Nova can outshine and entire galaxy and radiate stellar matter at speeds up to 10% the speed of light. This particular Super Nova was given the name SN 1572. SN 1572 is also known as Tycho's Supernova, Tycho's Nova, "B Cassiopeiae" (B Cas), or 3C 10. This Super Nova is located in the constellation Cassiopeia. It is one of one of about eight supernovae visible to the naked eye in historical records. It burst forth in early November 1572 and was independently discovered by many individuals.
