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.

Enceladus’ tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s south pole and creating Saturn’s mysterious E-ring. Evidence for this has come from NASA’s Cassini spacecraft that orbited Saturn from 2004 to 2017. Pictured here, a high resolution image of Enceladus is shown from a close flyby. Tiger stripes are visible in false-color blue. Image credit: NASA / ESA / JPL / SSI / Cassini Imaging Team.

Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 1,550 miles (2,500 km) from the surface of the planet. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene shows the entire Valles Marineris canyon system, over 1,240 miles (2,000 km) long and up to 5 miles (8 km) deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 15.5 miles (25 km) high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.

This Hubble image shows the open star cluster NGC 330. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

$The largest crustal block Byrne et al. identified in the Venus lowlands: (A) Magellan radar image mosaic of the block; named landforms are shown; the black and white arrows mark impact craters and prominent lava flows, respectively; the approximate outline of the campus is marked by a dashed yellow line; (B) radar image (left) and structural sketch (right) of extensional faults curving into the main groove belt that delineates the southwestern margin of this campus, here with a right-lateral sense of slip; (C) sigmoidal, positive-relief landforms we interpret as right-lateral transpressive structures; (D) another example of sigmoidal, positive-relief ridges we regard as denoting right-lateral transpression, with a different strike from those structures in (C); in these and subsequent structural sketches, prominent extensional structures are in purple (with ball-and-bar symbols shown on example down-thrown blocks), and prominent shortening structures are in teal (with sawtooth symbols on example upper blocks); minor and/or poorly expressed fractures of various types are shown as thin, black lines; wrinkle ridges are generally not recorded; exemplar extensional and shortening landforms are marked with gold and red arrows, respectively; the radar look direction is from the left in (A), and from the right in (B-D). All images are in azimuthal equidistant projection, centered at 24.5°S, 146.5°E (A); 20.0°S, 138.3°E (B); 27.2°S, 141.1°E (C); and 18.0°S, 145.0°E (D).
