An international team of astronomers has found one of the universe's biggest superclusters of galaxies near the Milky Way.
Researchers said the Vela supercluster, which had previously gone undetected as it was hidden by stars and dust in the Milky Way, was a huge mass that influenced the motion of our galaxy.
The gravity of the Vela supercluster may explain the difference between the measured motion of the Milky Way through space and the motion predicted from the distribution of previously mapped galaxies.
Anglo-Australian Telescope was used to measure distances for many galaxies to confirm earlier predictions that Vela was a supercluster.
