Composite image of the Swan Nebula. SOFIA detected the blue areas (20 microns) near the center, revealing gas as it’s heated by massive stars located at the center and the green areas (37 microns) that trace dust as it’s warmed both by massive stars and nearby newborn stars. The nine never-before-seen protostars were found primarily in the southern areas. The red areas near the edge represent cold dust that was detected by the Herschel Space Telescope (70 microns), while the white star field was detected by the Spitzer Space Telescope (3.6 microns). The space telescopes could not observe the blue and green regions in such detail because the detectors were saturated. SOFIA’s view reveals evidence that parts of the nebula formed separately to create the swan-like shape seen today. Credits: NASA/SOFIA/De Buizer/Radomski/Lim; NASA/JPL-Caltech; ESA/Herschel

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
