Dust glows blue in this image of Messier 35, a young star cluster in Gemini. Some of the dust, which reflects starlight, is left over from the cluster’s birth. The cluster is about 175 million years old and about 3,000 light-years away. A second cluster, NGC 2158, forms a tight white group to the lower right of center. [Canada-France-Hawaii Telescope/2003]
