Three dwarf spheroidal galaxies found to rotate
An international team of astrophysicists from the Instituto de Astrofísica de Canarias (IAC), the University of La Laguna (ULL) and the Space Telescope Science Institute (STScI, U.S.) has discovered the presence of transverse rotation (in the plane of the sky) in three dwarf spheroidal galaxies. These are a very faint type of galaxy and are quite difficult to observe. These new findings help to trace their evolutionary history. The finding was made using the most recent data from the GAIA satellite of the European Space Agency. The results of the study have just been published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).
