... 2015 April 6 . NGC 3293: A Bright Young Star Cluster . ... Open cluster NGC 3293 is located in the constellation Carina , lies at a distance of about 8000 light years , and has a particularly high abundance of these young bright stars. A study of NGC 3293 implies that the blue stars are only about 6 million years old, whereas the cluster's dimmer, redder stars appear to be about 20 million years old. If true, star formation in this open cluster took at least 15 million years. ...
