Quantum scrambling is one suggestion for how information can fall into a black hole and come out as random-looking radiation. Perhaps, the argument goes, it is not random at all, and black holes are just excellent scramblers. Image credit: E. Edwards / Joint Quantum Institute.

This composite image shows the starburst galaxy Messier 82. The magnetic field detected by SOFIA, shown as streamlines, appears to follow the bipolar outflows (red) generated by the intense nuclear starburst. The image combines visible starlight (gray) and a tracing of hydrogen gas (red) from the Kitt Peak Observatory, with near-infrared and mid-infrared starlight and dust (yellow) from SOFIA and NASA’s Spitzer Space Telescope.

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.

Sesquizygosis -- whereby twins are genetically identical to each other with respect to one parent but differ from each other by approximately 50% with respect to the composition of DNA inherited from the other parent -- is a third form of twinning. Genetically, sesquizygosis can be considered to be on a continuum between monozygosis and dizygosis. It probably arises after heterogoneic assortment of two paternal genomes and one maternal genome during the first postzygotic cleavage division.

This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

This composite picture combines nine individual images taken with New Horizons’ Long Range Reconnaissance Imager (LORRI), each with an exposure time of 0.025 seconds, just 6 ½ minutes before the spacecraft’s closest approach to Ultima Thule. The image was taken at 12:26 a.m. EST (5:26 a.m. GMT) on January 1, 2019, when the spacecraft was 4,109 miles (6,628 km) from Ultima Thule and 4.1 billion miles (6.6 billion km) from Earth. The angle between the spacecraft, Ultima Thule and the Sun -- known as the ‘phase angle’ - was 33 degrees.
