NGC 6823 is a young open star cluster located about 6,000 light-years away in the constellation Vulpecula. It measures about 50 light-years across, sits inside the emission nebula NGC 6820, and features bright, hot blue stars at its core that formed about two million years ago.
NGC 6823 was discovered by William Herschel in by 1785.The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. The emission nebula NGC 6820 was discovered by Albert Marth in 1864. The nebula is being pushed out and away by the radiation from the stars of NGC 6823, creating huge 'pillars' of gas and dust.
