NGC 6156 is a 11.6 likes bright barred spiral galaxy with an active galactic nucleus from Hubble type SBc in the constellation Corona Australis. It is an estimated 141 million light years away from the Milky Way and about 70,000 light years in diameter.
The object was discovered on April 24, 1835 by John Herschel with an 18-inch reflector telescope, which during two observations "pF, R, gpmbM, 45 arcseconds, in a field full of small stars" and "pF, lE, glbM, 50 arcseconds long ”.
