1806−20 cluster

Heavily obscured star cluster on the far side of the Milky Way

1806−20 is a heavily obscured star cluster on the far side of the Milky Way, approximately 28,000 light-years distant. Some sources claim as far as 50,000. It contains the soft gamma repeater SGR 1806−20 and the luminous blue variable hypergiant LBV 1806−20, a candidate for the most luminous star in the Milky Way. LBV 1806−20 and many of the other massive stars in the cluster are thought likely to end as supernovas in a few million years, leaving only neutron stars or black holes as remnants.
