Dark energy could be measured by studying the galaxy next door

Researchers, from the University of Cambridge, found that it may be possible to detect and measure dark energy by studying Andromeda, our galactic next-door neighbour that is on a slow-motion collision course with the Milky Way.

Using a series of simulations based on the best available estimates of the mass of both galaxies, Dr David Benisty and his co-authors – Professor Anne Davis from DAMTP (KICC member) and Professor Wyn Evans from the Institute of Astronomy – found that dark energy is affecting how Andromeda and the Milky Way are orbiting each other.
