When flying past Venus on July 11, 2020, the WISPR instrument onboard Parker Solar Probe detected a bright rim around the edge of the planet that may be nightglow. The prominent dark feature in the center of the image is Aphrodite Terra, the largest highland region on the Venusian surface. Bright streaks in WISPR, such as the ones seen here, are typically caused by a combination of cosmic rays, sunlight reflected by grains of space dust, and particles of material expelled from the spacecraft’s structures after impact with those dust grains. The number of streaks varies along the orbit or when the spacecraft is traveling at different speeds, and scientists are still in discussion about the specific origins of the streaks here. The dark spot appearing on the lower portion of Venus is an artifact from the WISPR instrument.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter captured this image of the larger of Mars’ two moons, Phobos, on March 23, 2008. The image was taken from a distance of about 6,800 km (about 4,200 miles). It is presented in color by combining data from the camera’s blue-green, red, and near-infrared channels. The illuminated part of Phobos seen in the image is about 21 km (13 miles) across. The most prominent feature is the large crater Stickney in the lower right. With a diameter of 9 km (5.6 miles), it is the largest feature on Phobos. Image credit: NASA / JPL-Caltech / University of Arizona.
