A Bridge of Dark Matter Detected

  Direct measurement of a dark-matter ‘filament’ confirms its existence in a galaxy supercluster.   A ‘finger’ of the Universe’s dark-matter skeleton, which ultimately dictates where galaxies form, has been observed for the first time. Researchers have directly detected a slim bridge of dark matter joining two clusters of galaxies, using a technique that could [continue reading]

Herschel reveals galaxy-packed filament

  A McGill-led research team using the Herschel Space Observatory has discovered a giant, galaxy-packed filament ablaze with billions of new stars. The filament connects two clusters of galaxies that, along with a third cluster, will smash together and give rise to one of the largest galaxy superclusters in the universe.
