This mosaic of the southern sky was assembled from 208 TESS images. Among the many notable celestial objects visible is the glowing band (left) of the Milky Way, our home Galaxy seen edgewise, the Orion Nebula (top), a nursery for newborn stars, and the Large Magellanic Cloud (center), a nearby galaxy located about 163,000 light-years away. The prominent dark lines are gaps between the detectors in TESS’ camera system. Image credit: NASA / MIT / TESS / Ethan Kruse, USRA.

This composite image shows Abell 1758, a quadruple galaxy cluster system about 3 billion light-years away from Earth. In the northern (top) pair seen in the image, the centers of each cluster have already passed by each other once, about 300 to 400 million years ago, and will eventually swing back around. The southern pair at the bottom of the image has two clusters that are close to approaching each other for the first time. X-rays from Chandra are shown as blue and white, depicting fainter and brighter diffuse emission, respectively. This image also includes an optical image from the Sloan Digital Sky Survey (SDSS).

This Hubble image shows the face-on spiral galaxy NGC 1706. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This image of Tycho’s SNR from NASA’s Chandra X-ray Observatory reveals an intriguing pattern of bright clumps and fainter holes. To emphasize these features, two narrow ranges of X-ray energies were selected to isolate material (silicon, colored red) moving away from Earth, and moving towards us (also silicon, colored blue). The other colors in the image (yellow, green, blue-green, orange and purple) show a broad range of different energies and elements, and a mixture of directions of motion. Chandra’s X-ray data are shown alongside an optical image of the stars in the same field of view from the Digitized Sky Survey.
