This beautiful star cluster, captured by Hubble, has the very unromantic name of NGC 290. An open cluster like this one, as opposed to a globular cluster, tends to be younger and so has many more bright blue stars. Since all of the stars in an open cluster were born at around the same time, astronomers find them useful for studying how stars of differing masses evolve differently.
