Astrophysicists unveil biggest-ever 3D map of Universe


GENEVA: Astrophysicists on Monday published the largest-ever 3D map of the Universe, the result of an analysis of more than four million galaxies and ultra-bright, energy-packed quasars.

The efforts of hundreds of scientists from around 30 institutions worldwide have yielded a "complete story of the expansion of the universe", said Will Percival of the University of Waterloo in Ontario, Canada.

In the project launched more than two decades ago, the researchers made "the most accurate expansion history measurements over the widest-ever range of cosmic time", he said in a statement.
