Hubble moments: Robert Kirshner

Robert Kirshner was part of the supernova team that used Hubble to discover the accelerating expansion of the universe which led to a 2011 Nobel Prize for his students. In this Nature Video, Kirshner tells us his favourite Hubble moment: a particular supernova which sparked his imagination, 1987A.
