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). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
