How can a galaxy full of billions of stars be considered small and lonely?

This striking explosion of cosmic people of colour is the galax DDO 190 . But whatever its esthetic merits , it ’s nothing special in scientific terms — indeed , it ’s rather unflatteringly termed a dwarf irregular galaxy . It ’s also one of the loneliest galaxies around .

While it ’s kind of hard to believe it when looking at this beautiful prototype from the Hubble Telescope , DDO 190 is take a relatively unimpressive galactic specimen due to its small sizing and deficiency of structure . It ’s the variety of minor galaxy that would get lost in the shuffle around a larger galaxy like our own Milky Way , which completely eclipse its little artificial satellite beetleweed , the Magellanic Clouds . Weirdly , that ’s about the only matter small DDO 190 has endure for it . Completely disjunct from all other galaxies , it ’s the rarified gnome beetleweed that really receive a prospect to gleam . NASA explains :

DDO 190 rest around nine million light - years out from our solar system . It is deliberate part of the loosely tie in Messier 94 group of galaxy , not far from the Local Group of galaxies that includes the Milky Way . Canadian stargazer Sidney van der Bergh was the first to immortalize DDO 190 in 1959 as part of the DDO catalog of dwarf galaxies . Although within the Messier 94 mathematical group , DDO 190 is on its own . The wandflower ’s nearest dwarf galaxy neighbor , DDO 187 , is thought to be no closer than three million light - twelvemonth off . In dividing line , many of the Milky Way ’s companion galaxies , such as the Large and Small Magellanic Clouds , reside within a fifth or so of that aloofness , and even the gargantuan helix of the Andromeda Galaxy is closer to the Milky Way than DDO 190 is to its nearest neighbor .
