Context: Using the Hubble Space Telescope, astronomers have discovered a dwarf galaxy in a globular cluster which is only 30 million light-years away.

The researchers determined that this galaxy — nicknamed Bedin 1, after discovery team leader L. R. Bedin of the INAF-Osservatorio Astronomico di Padova in Italy — is a “spheroidal dwarf” just 3,000 light-years wide.
