Ngc 6820 (also known as Sh2-86) is an emission nebula associated with the open star cluster Ngc 6823 in the constellation Vulpecula. The most striking feature of the NGC 6820 nebula is the post (or pillar) pointing towards the NGC 6823 open cluster.
Around the cluster, lots of other pillars are visible. Dark “Bok” globules of gas and dust are also visible, where new stars are born.
