Title:
Stars Without Galaxies
Explanation:
Galaxies are made up [ http://antwrp.gsfc.…] of stars, but are all stars found within galaxies [ http://antwrp.gsfc.…]? Using the Hubble Space Telescope, researchers exploring the Virgo Cluster of galaxies [ http://bozo.lpl.ari…] have now found about 600 red giant stars adrift in intergalactic space [ http://oposite.stsc…]. Above is an artist's vision of the sky from a hypothetical planet of such a lonely sun. The night sky on a world orbiting an intergalactic star would be a stark contrast to Earth's - which features a spectacle of stars, all members of our own Milky Way galaxy [ http://antwrp.gsfc.…]. As suggested by the illustration, a setting swollen red sun would leave behind a dark sky flecked only with faint, fuzzy, apparitions of Virgo Cluster galaxies [ http://antwrp.gsfc.…]. Possibly ejected from their home galaxies during galaxy-galaxy collisions [ http://antwrp.gsfc.…], these isolated suns may well represent part of a large, previously unseen [ http://oposite.stsc…] stellar population, filling the space between [ http://imagine.gsfc…asca_abundance.html ] Virgo Cluster galaxies.
