A group of astronomers has released a dataset based on 32 nights of repeated observations of supernova 2011fe, creating a "gold-standard" atlas for Type 1a supernovae.
An extraordinarily bright, extraordinarily long-lasting supernova named SN 2007bi, snagged in a search by a robotic telescope, turns out to be the first example of the kind of stars that first populated the Universe.
