This new image from the NASA/ESA Hubble Space Telescope shows the spiral galaxy NGC 3749. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / D. Rosario et al.

This image from NASA’s Mars Reconnaissance Orbiter shows Jezero Crater on Mars, the landing site for NASA’s Mars 2020 mission. On ancient Mars, water carved channels and transported sediments to form fans and deltas within lake basins. Examination of spectral data acquired from orbit show that some of these sediments have minerals that indicate chemical alteration by water. Here in Jezero Crater delta, sediments contain clays and carbonates. Image credit: NASA / JPL-Caltech / MSSS / JHU-APL.

This Hubble image shows a massive galaxy cluster, about 4.6 billion light years away. Along its borders 12 images within the four arcs are visible; these are copies of the same galaxy called PSZ1 G311.65-18.48, which is almost 11 billion light-years away. Three of these arcs are visible in the top right of the image, while one counterarc is visible in the lower left -- partially obscured by a bright foreground star within our Milky Way Galaxy.

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).
