Hubble Sequence


For the first time (perhaps this is a bit of a stretch on the part of the authors), two astronomers have explained the diversity of galaxy shapes seen in the universe. The scientists, Dr Andrew Benson of the California Institute of Technology (Caltech) and Dr Nick Devereux of Embry-Riddle University in Arizona, tracked the evolution of galaxies over thirteen billion years from the early Universe to the present day. Their results appear in the journal Monthly Notices of the Royal Astronomical Society. (Image illustrating the Hubble Sequence appears above: Ville Koistinen)
