This area, two degrees across, is centred on the area where the famous Tycho’s Supernova, also known as, SN 1572A, exploded in 1572. The region lies in the constellation of Cassiopeia in the northern sky. The image was composed from two exposure from the Digitized Survey 2. The red exposure is shown in blue and the infrared in red. In this optical and near-infrared image the supernova remnant itself is not visible.
