Barnard's Galaxy 소개

설명

Barnard's Galaxy (NGC 6822) is a dwarf irregular galaxy in Sagittarius, about 1.6 million light-years away. It is a member of the Local Group and one of the closest galaxies beyond the Magellanic Clouds, with active star formation and numerous HII regions.

관측 팁

A challenging target due to low surface brightness and low declination from northern latitudes. Requires dark skies and at least a 6-inch telescope. Appears as a faint, large, irregular glow. Best in summer when Sagittarius is highest.

역사

Discovered by E.E. Barnard in 1884 using a 6-inch refractor. It was one of the first galaxies recognized as lying beyond the Milky Way when Edwin Hubble identified Cepheid variables in it in 1925.

재미있는 사실

Barnard's Galaxy is one of the few galaxies discovered visually in the late 19th century rather than photographically. It contains a giant bubble of ionized hydrogen about 1,500 light-years across, one of the largest HII complexes in the Local Group.
