Most detailed map of nearby Universe completed

Researchers from Australia, the UK and the USA have just completed the most detailed survey of galaxies in the nearby Universe, which will reveal not only where the galaxies are but also where they are heading, how fast, and why.

Galaxies are tugged around by each other's gravity. By measuring the galaxies' movements, the researchers can map the gravitational forces at work in the local Universe, and so show how matter, seen and unseen, is distributed.

The survey shows strings and clusters of nearby galaxies on large scales in unprecedented detail, and has revealed more than 500 voids? apparently empty areas of space with no galaxies.

- Motion Of Stars In Distant Galaxy
Astronomers have measured the motions of stars for the first time in a very distant galaxy, speeding around its host at twice the speed of our Sun through the Milky Way. The speeding stars may help astronomers understand how such compact galaxies form...
