The bulk of material between the stars in our Milky Way galaxy-the cool hydrogen gas from which stars spring-is nearly impossible to find.
The new mega-galaxy was originally spotted by a post-doctoral researcher at UCI in an image recorded by the European Space Agency`s Herschel telescope.
The formation of new stars in galaxies like the Milky Way has declined five-fold in the last 3bn years.
Europe`s new space telescope, Herschel, has observed the "death throes" of the biggest star known to science till date.
