Dark Energy Survey finds more celestial neighbors

27 Agosto 2015

Eight new dwarf galaxy “neighbors” of the Milky Way discovered in recent data from the Dark Energy Survey (DES). More than 20 such companions to our galaxy have been discovered this year, of which 17 were found in DES data. Dwarf satellite galaxies may provide valuable clues to the nature of dark matter and how galaxies like the Milky Way formed. The Dark Energy Survey is being carried out on the 4-m Blanco telescope at CTIO.
