NGC 206, a stellar association in the Andromeda galaxy, appears at the center of a detailed image of the southwestern region of the galaxy's disk. Located 2.5 million light-years away, NGC 206 contains bright, blue stars indicating youth. The youngest massive stars in the association are less than 10 million years old.
NGC 206 spans about 4,000 light-years across. This makes it much larger than open clusters in the Milky Way's disk and comparable in size to NGC 604 in the spiral galaxy M33 and the Tarantula Nebula in the Large Magellanic Cloud. Pink star-forming regions surround NGC 206 within Andromeda's dusty arms.
