History of Supernova Detections

A history of Supernovae explosions as recorded on the IAU Central Bureau for Astronomical Telegrams (CBAT: http://www.cbat.eps.harvard.edu) between 1985 and November 2013. Note the general increase in the Supernova discovery rate over the ~30 year timespan. Also note the impact of dedicated Supernovae searches, e.g. SDSS in 2001, 2006 and 2007, giving rise to occasional very high density stripes across the sky. The background image is made from star counts in the UCAC3 (http://tdc-www.harvard.edu/catalogs/u...) catalogue, and is shown in a Galactic coordinate Mollweide projection.
