Amateur astronomers ‘swipe right’ to identify nearly a quarter million galaxies

An ambitious galaxy-mapping mission has identified nearly 250,000 galaxies in a quest to better understand dark energy, the mysterious force that is causing the universe to expand at an accelerating rate.

The results provided by the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX), located at the University of Texas at Austin’s McDonald Observatory, would not have been possible without the assistance of more than 10,000 amateur astronomers to help with its discovery.
