This Hubble image shows NGC 2164, a young open cluster located some 160,000 light-years away in the constellation of Dorado. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through four 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.

Wilkins et al. observed bright flares of X-ray emissions, produced as gas falls into a supermassive black hole in I Zwicky 1; the flares echoed off of the gas falling into the black hole, and as the flares were subsiding, short flashes of X-rays were seen -- corresponding to the reflection of the flares from the far side of the disk, bent around the black hole by its strong gravitational field.

This Hubble image shows the galaxy cluster MACS J0138.0-2155, which is so massive that its gravity bent and magnified light streaming not only from an extremely distant background galaxy but also from a supernova event in this galaxy. The color image was made using observations from eight different filters spread across Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Newman / M. Akhshik / K. Whitaker.

This Hubble image shows NGC 6380, a globular cluster some 35,500 light-years away in the constellation of Scorpius. The very bright star at the top of the image is HD 159073, which is only around 4,000 light-years from Earth. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3).
