Sh2-37 is a hydrogen emission nebula with two small blue reflection nebulae, embedded in a dusty background against the core of the Milky Way.

Less than 500 light-years away and blocking light from more distant, background stars in the Milky Way, the densest part of the dust cloud of Caldwell 68 is about 8 light-years long. At its tip is a group of reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust.

Centaurus A is a peculiar galaxy discovered in 1826 by Scottish astronomer James Dunlop in Parramatta, Australia. It is ~10-16 million light years away and its lenticular with dust lanes hybrid appearance is the result of a merge of two galaxies.
