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.

Fornax dwarf spheroidal galaxy.

One subclass of dwarf galaxies are the dwarf spheroidals.

They are very diffuse, with low luminosity, and contain large proportions of dark matter with little or no gas.

The galaxy is about 30 million light-years away, is classified as a dwarf spheroidal galaxy and has been nicknamed Bedin 1, after the principal investigator.
