In Friday’s of the journal Science, conclusions from the Cosmic Infrared or CIBER, suggest that as many as half of all stars in our universe may lie outside the home of galaxies. Not visible through Earth- telescopes due to their faint , these lone stars may be the points that connect galaxies together in a far spanning web of light.   

These ‘homeless’ stars are believed by astronomers to have been evicted by their galaxies by mergers and collisions.
