Schematics of the observations of TYC 8998-760-1b using SINFONI on ESO’s Very Large Telescope. The background image is captured by the SPHERE instrument on the Very Large Telescope. The small blue box marks the field of view of SINFONI observations targeting TYC 8998-760-1b. Both the host star and TYC 8998-760-1c are outside the field of view. An example of the wavelength-collapsed image is shown in the enlarged blue box, showing negligible contribution from starlight. Image credit: ESO / Bohn et al. / Zhang et al.

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.
