Title:
Stars Without Galaxies
Explanation:
Galaxies are [ http://antwrp.gsfc.…] made up of stars, but are all stars [ http://antwrp.gsfc.…] found within galaxies? Using the Hubble Space Telescope, researchers exploring [ http://xxx.lanl.gov…] the Virgo Cluster [ http://bozo.lpl.ari…] of galaxies have 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 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 [ http://antwrp.gsfc.…] collisions, these isolated suns may well represent part of a large, previously unseen [ http://oposite.stsc…darkmatt.txt ] stellar population, filling the space between [ http://imagine.gsfc…asca_abundance.html ] Virgo Cluster galaxies.
