This image shows the merger of two galaxies, known as NGC 7752 (larger) and NGC 7753 (smaller), also collectively called Arp86. In these images, different colors correspond to different wavelengths of infrared light. Blue and green are wavelengths both strongly emitted by stars. Red is a wavelength mostly emitted by dust.

Amid the bright light of its member galaxies, the galaxy cluster MACS J0416.1-2403 also emits a soft glow of intracluster light, produced by stars that are not part of any individual galaxy. These stars were scattered throughout the cluster long ago, when their home galaxies were torn apart by the cluster's gravitational forces. The homeless stars eventually aligned themselves with the gravity of the overall cluster. Hubble's unique sensitivity and resolution captures the faint light and uses it to trace the location of invisible dark matter, which dominates the cluster's gravitational field.

As the jet from the neutron-star merger event emerged into space, simulated radio images in this artist's conception illustrate its extremely fast motion. In the 155 days between two observations, the jet appeared to move two light-years, a distance that would require it to travel four times faster than light. This "superluminal motion" is an illusion created as the jet is pointed nearly toward the Earth and it is actually moving more than 97 percent of light speed. (Not to Scale.) Credit: D. Berry, O. Gottlieb, K. Mooley, G. Hallinan, NRAO/AUI/NSF
