This spectacular image from ESO’s VLT Survey Telescope shows the Cat’s Paw Nebula (upper right) and the Lobster Nebula (lower left); these dramatic objects are regions of active star formation where the hot young stars are causing the surrounding hydrogen gas to glow red; the very rich field of view also includes dark clouds of dust; with around two billion pixels this is one of the largest images ever released by ESO.

A DNA coverage plot for Escherichia coli following 60 generations (96 h) of growth in the presence and absence of doxycycline: data in the presence (three inner annuli, ‘Dox’) and absence (three outer annuli, ‘No-Dox’) indicate potential genetic mechanisms supporting positive r (growth rate), K (carrying capacity) and resistance adaptation; a change in DNA detected in the sequencing protocol is shown in red (reduction) and blue (increase; and white is complete loss), respectively, with respect to no mean change (in grey); the inner ring (black) indicates genome position and three replicates for each treatment were sequenced; the white region marked dlp12 shows the deletion of prophage dlp12 only during doxycycline treatment; the outer text labels summarize the estimated frequencies of mutations common to all three replicate populations, indicating positive selection for the doxycycline efflux operon, acr, with the prophage deletion at even higher frequency.

This Cassini image features a density wave in Saturn’s A ring (at left) that lies around 83,575 miles (134,500 km) from Saturn. Density waves are accumulations of particles at certain distances from the planet. This feature is filled with clumpy perturbations, which researchers informally refer to as ‘straw.’ The wave itself is created by the gravity of Saturn’s moons Janus and Epimetheus, which share the same orbit around the gas giant. Elsewhere, the scene is dominated by ‘wakes’ from a recent pass of the ring moon Pan. The image was taken in visible light with Cassini’s wide-angle camera on December 18, 2016. The view was obtained at a distance of approximately 34,000 miles (56,000 km) from the rings and looks toward the unilluminated side of the rings.

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.
