Govert Schilling
ALBUQUERQUE, NEW MEXICO--A striking image presented here 3 June at a meeting of the American Astronomical Society shows a globular cluster known as Palomar 5 being torn asunder by tidal forces of our home galaxy. Researchers say the observation and others like it could shed new light on the distribution of dark matter in the halo of the Milky Way.
