Star Clusters in the Southern Constellation, Doradus. Star clusters 166,000 light-years away in the Large Magellanic Cloud (LMC), in the southern constellation Doradus. The field of view is 130 light-years across. There are three separate populations in this concentration of nearly 10,000 stars down to the 25th magnitude (more than twice as many as can be seen over the entire sky with the naked eye on a clear night on Earth). About 60 percent of the stars belong to the dominant yellow cluster called NGC 1850, which is estimated to be 50 million years old. A scattering of white stars in the image are massive stars that are only about 4 million years old and represent about 20 percent of the stars in the image. The remainder are field stars in the LMC. Yellow stars correspond to Main Sequence stars like our Sun; red stars are cool giants and supergiants; and, white stars are hot young stars. Credit: R.
