From KenCroswell.com:<br /><br />Most of the intergalactic stars in the Virgo cluster are old and surprisingly metal-poor, say astronomers who have used the Hubble Space Telescope to discover thousands of such stars. The low metallicity suggests that the stars were born both in small Virgo galaxies which disintegrated and at the edges of the large galaxies which tore the small ones apart.
