Description

NGC 6188 is an emission nebula located about 4,000 light years away in the constellation Ara.

The bright and young open cluster NGC 6193 (left), is responsible for a region of reflection nebulosity within NGC 6188.

NGC 6193 (Caldwell 82) and its emission counterpart NGC 6188 are seen in projection along the edge of a molecular cloud and immense expanding bubble of neutral hydrogen gas spanning some 300 light years. Ultraviolet radiation from the O-type giants of NGC 6193 is presently eroding the eastern edge of the parent molecular cloud and may be triggering and sustaining further star formation in other regions within it.
