NGC 206 is a bright star cloud in the Andromeda Galaxy, and the brightest star cloud in Andromeda when viewed from Earth. It was discovered by German-born English astronomer William Herschel in 1786.

NGC 206 is the richest and most conspicuous star cloud in the Andromeda Galaxy, and is one of the largest and brightest star-forming regions in the Local Group.
It contains more than 300 stars brighter than Mb=−3.6.
It was originally identified by Edwin Hubble as a star cluster.

NGC 206 is located in a spiral arm of the Andromeda Galaxy, in a zone free of neutral hydrogen.
It contains hundreds of stars of spectral types O and B. The star cloud has a double structure: one region has an age of around 10 million years and includes several H II regions in its border;
the other region has an age of 40 to 50 million years and includes a number of cepheids. The two regions are separated by a band of interstellar dust.(wiki)
