Stars Without Galaxies.

Galaxies are made up of stars, but are all stars found within galaxies? Using the Hubble Space Telescope , researchers exploring the Virgo Cluster of galaxies have now found about 600 red giant stars adrift in intergalactic space . 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 . 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 . Possibly ejected from their home galaxies during galaxy-galaxy collisions , these isolated suns may well represent part of a large, previously unseen stellar population, filling the space between Virgo Cluster galaxies.
