NASAs Dawn space mission has found evidence for organic material on asteroid (or dud comet) Ceres – see https://phys.org/print406465509.html … the material was detected near a crater and the study is in this month's Science journal (February 2017). Carbonates and clays have also been discovered. The organic material is part of the stuff of life – but apparently not evidence of life on Ceres.
