... 2003 December 15 . Open Star Clusters M35 and NGC 2158 . ... NGC 2158 is four times more distant that M35 , over 10 times older, and much more compact as it contains many more stars in roughly the same volume of space. NGC 2158 's bright blue stars have self-destructed , leaving cluster light to be dominated by older and yellower star s. Both clusters are visible toward the constellation of Gemini -- M35 with binoculars and NGC 2158 with a small telescope. ... About APOD | ...
