Credit: NASA/[[ESA/HST]] CL0024+17, or CL0024+1654, is a cluster of galaxies located in the constellation Pisces, and about 4 billion light years distant. It appears as a concentration of yellow elliptical and spiral type galaxies. It has a radius of 0.54 mpc and a mass of 8.1x10^14 solar masses. The cluster's large mass gravitationally lensed a background galaxy, creating eight well-resolved images of this galaxy.

Cl 0024+17 is allowing astronomers to probe the distribution of dark matter in space. The blue streaks near the center of the image are the smeared images of very distant galaxies that are not part of the cluster. The distant galaxies appear distorted because their light is being bent and magnified by the powerful gravity of Cl 0024+17, an effect called gravitational lensing.
