In studying the dimmest burned-out stars in globular star cluster NGC 6791, NASA's Hubble Space Telescope has uncovered a paradox: three different populations of stars exist in an object where all the stars should have formed at the same time out of an interstellar cloud of gas and dust. NGC 6791 is located 13,300 light-years away in the constellation Lyra. The field is full of stars estimated to be 8 billion years old. Two background galaxies can be seen at upper left.
