3D map of our nearby Universe

Researchers created 3D video map of our nearby Universe to a distance of 300 million light-years. The map is the most detailed map ever created, showing our neighborhood through a series of dynamic rotated, panned and zoomed 3D representations.

The 3D map also shows the distribution of dark matter (about 80% of the total matter in the universe) and energy.

Our Milky Way is situated in the Local, or Virgo, Supercluster, containing the Virgo Cluster and the Local Group. At least 54 galaxy groups and clusters have been found within its diameter.

The cosmography video ends with a ‘fanciful view of the Supergalactic equator.’ This cosmography only represents around 0.32% of the entire universe. The visible universe extends 93 billion light years away.

The best estimate of the age of the universe as of 2013 is 13.798 ± 0.037 billion years but due to the expansion of space humans are observing objects that were originally much closer but are now considerably farther away (as defined in terms of cosmological proper distance, which is equal to the comoving distance at the present time) than a static 13.8 billion light-years distance. The diameter of the observable universe is estimated at about 28 billion parsecs (93 billion light-years), putting the edge of the observable universe at about 46–47 billion light-years away.

The video map was compiled by Hélène Courtois, Daniel Pomarède, R. Brent Tully, Yehuda Hoffman and Denis Courtois.
