NGC 6221 & NGC 6215

NGC 6221 & 6215.

NGC 6221 (top right) is a barred spiral galaxy in Ara at about 70 MLY distance. NGC 6221 and NGC 6215 (bottom left) are part of a galaxy group joined by a double stranded bridge of neutral hydrogen gas. Three faint dwarf galaxies are also part of this system. One of these faint dwarfs is marked by red pointers.

The striking number of foreground stars is because this system is in the Milky Way and also at the low galactic latitude of only 10 degrees, close to the “zone of avoidance” where dense clouds of dust dim any background stars.
