Galaxy Cluster Abell 2764
This region of space contains hundreds of galaxies in a halo of dark matter. Dark matter is literally invisible—it is not directly detectable by scientific instruments—but astronomers know it’s there because of its gravitational effects on things we can see. The bright star towards the bottom of the image is V*BP-Phoenicis, which is in the Milky Way. Euclid mitigates the scattering of light from the foreground star, so that the brilliant, distant background—around 1 billion light-years from Earth—is visible.
