This image of an impact crater in the Sirenum Fossae region of Mars was taken by NASA’s Mars Reconnaissance Orbiter on March 30, 2015. The crater is approximately 3,300 feet (1-km) wide and appears relatively recent as it has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Image credit: NASA / JPL / University of Arizona / Alfred McEwen.

Artist’s impression of C/2014 S3 (PanSTARRS). The comet’s current long orbital period (approximately 860 years) suggests that its source is in the Oort Cloud -- a large region surrounding the Sun like a giant, thick soap bubble -- and it was nudged comparatively recently into an orbit that brings it closer to the Sun.
