Galaxy Cluster Abell 2390
Another galaxy cluster imaged by Euclid’s recent campaign is Abell 2390, which is a significant 2.7 billion light-years from Earth. If you look closely at the cluster of bright objects near the center of the image, you’ll see intracluster light—light from stars separated from their galaxies and spread across intergalactic space. Euclid can use this intracluster light to see regions that contain concentrations of dark matter. Euclid can take perceptive, wide field images like this one much faster than other telescopes.
