One of 10 high-redshift (z>1.5) type-Ia
supernovae in the Subaru Deep Field, SNSDF0806.50, at redshift
z=1.7, exploded 10
billion years ago. The supernova is
highlighted by an arrow in the bottom panel of the inset, imaged in
June 2008. The top panel shows the same area a year before the
supernova occurred. The unchanging red spot is the distant galaxy in which the supernova occurred.
