Photo of metallic hydrogen at a pressure of 495 GPa; the sample is non-transmitting and is observed in reflected light; the central region is clearly more reflective than the surrounding metallic rhenium gasket; the sample dimensions are approximately 8-10 microns with thickness 1.2 microns.

The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus. The colors in the spectra show dips, the size of which reveal the amount of these elements in the atmosphere of a star. The human body on the left uses the same color coding to evoke the important role these elements play in different parts of our bodies, from oxygen in our lungs to phosphorous in our bones (although in reality all elements are found all across the body). In the background is an artist’s impression of the Galaxy, with cyan dots to show the APOGEE measurements of the oxygen abundance in different stars; brighter dots indicate higher oxygen abundance.

B.H.C. Emonts et al found that the Spiderweb, a massive galaxy in the center of a distant protocluster, is forming from a large reservoir of molecular gas. In this artist’s conception of the protocluster, the protogalaxies are shown in white and pink, and the blue indicates the location of the carbon monoxide gas. Image credit: M. Kornmesser / ESO.

This HI4PI map was produced using data from the 100-m Max-Planck radio telescope in Effelsberg, Germany and the 64-m CSIRO radio telescope in Parkes, Australia. The image colors reflect gas at differing velocities. The plane of the Milky Way Galaxy runs horizontally across the middle of the image. The Magellanic Clouds can be seen at the lower right.

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.
