This Hubble image shows NGC 6717, a globular cluster located over 23,000 light-years away in the constellation of Sagittarius. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through five filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

MG B2016+112: the X-ray light from one of the objects on the left (purple) has been warped by the gravity of the intervening galaxy to produce two beams and X-ray sources (A and B) detected in the Chandra image, which is represented by the dashed square on the right; the X-ray light from the fainter object (blue) produces an X-ray source (C) that has been amplified by the galaxy to be as much as 300 times brighter than it would have been without the lensing; the Chandra image is shown in the inset; these two X-ray-emitting objects are likely a pair of growing supermassive black holes or a growing supermassive black hole and a jet.

Stretching 3,300 light-years, a collection of young stars and star-forming clouds in the Sagittarius arm of our Milky Way Galaxy is the first major structure identified with such a dramatically different orientation relative to an arm. The background image shows the location of the splinter in the Milky Way. The yellow region in the center of the image is the Galaxy’s bright and crowded center. The Milky Way’s arms spiral around the center, and are full of stars and star-forming clouds of gas and dust. The inset provides a closer view of the structure, as well as its size and distance from the Sun. The nearby spiral arms are also noted. The star shapes indicate a star-forming region that may contain anywhere from dozens to thousands of stars. These stars and star-forming regions are moving through space together, at roughly the same speed and in the same direction. Image credit: NASA / JPL-Caltech.
