Using the Hubble Space Telescope (HST), astronomers have detected three new ultra-faint dwarf galaxies associated with the nearby spiral galaxy NGC 253. The newly found dwarfs turn out to be among the faintest systems so far discovered beyond the Local Group. The finding is reported in a paper published August 20 on arXiv.org.
