“We have to accurately measure the shapes of over 1.5 billion distant galaxies,” explained Valeria Pettorino and René Laureijs, Euclid project scientists at the European Space Agency. “We will be able to also search for objects that were very difficult to detect before Euclid such as free floating planets, ultra-cold stars, brown dwarfs, galaxies with very low surface brightness or very high redshift quasar populations,” Pettorino and Laureijs said. Such clusters are so massive that they bend space-time, creating an effect called gravitational lensing, in which light from distant galaxies is warped and shows up as a distorted shape like a disk or an arc.
