Clumps of molecular gas overlaid on Sagittarius A* circumnuclear disk as seen by ALMA in the CS(7-6) line. Yellow circles are thin clumps that are going to be shredded by the gravitational force of supermassive black hole Sagittarius A*. Green circles are dense enough to survive the tidal shredding but are not able to form stars. Purple/pink circles have the needed density to form stars, but no star formation has been observed.

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.

This Hubble image shows the barred spiral galaxy NGC 1385. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3).
