This Hubble image shows a giant star called AG Carinae. The color image was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Planetary Camera 2 (WFPC2) and Wide Field Camera 3 (WFC3). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

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.

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.
