Messier 74 is a spiral galaxy like our Milky Way, which is seen face-on from Earth’s vantage point some 32 million light-years away. X-rays from Chandra (purple) have been combined with an infrared view of M74 from NASA’s James Webb Space Telescope (green, yellow, red, and magenta) as well as optical data from NASA’s Hubble Space Telescope (orange, cyan, and blue). In sonifying these data, a clockwise-moving radar-like scan starts around 12 o’clock. The distance from the center controls the frequencies of sound with light farther from the center being higher pitched. The Chandra sources correspond to relatively high musical pitches of glassy ethereal and clear plucked sounds. In the Webb data, large, medium, and small features are represented by low, medium, and high frequency ranges of pitches respectively with the brightest stars being heard as percussive sounds. The Hubble data have been turned into breathy synthesizer sounds along with thin metallic plucked sounds for bright stars and clusters.

The entire gamma-ray sky is unwrapped into a rectangular map, with the center of our Milky Way galaxy located in the middle, in this 14-year time-lapse of the gamma-ray sky. A moving source, our Sun, can be seen following a curving path through the sky, a reflection of Earth’s annual orbital motion. Watch for strong flares that occasionally brighten the Sun.

The central plane of our galaxy is on full display, glowing in gamma rays produced when accelerated particles (cosmic rays) interact with interstellar gas and starlight. Pulsars and supernova remnants, all bright gamma-ray sources for Fermi, also fleck the Milky Way band. Above and below the bright central plane, where our view of the broader cosmos becomes clearer, splotches of color brighten and fade. These sources are jets of particles moving at nearly the speed of light driven by supermassive black holes in distant galaxies. The jets happen to point almost directly toward Earth, which enhances their brightness and variability. Over a few days, these galaxies can erupt to become some of the brighest objects in the gamma-ray sky and then fade to obscurity.

In these maps, brighter colors indicate greater numbers of gamma rays detected by Fermi’s Large Area Telescope from Aug. 10, 2008, to Aug. 2, 2022.

The entire gamma-ray sky is shown as two circular views centered on the north (left) and south poles of our Milky Way galaxy in this 14-year time-lapse of the gamma-ray sky. The central plane of our galaxy wraps around the edges of both circles, suppressing its glow and improving the view of black-hole-powered galaxies in the distant universe. Their gamma rays come from jets produced by supermassive black holes in distant galaxies that point almost directly toward Earth, which enhances their brightness and variability. Over a few days, these galaxies can erupt to become some of the brighest objects in the gamma-ray sky and then fade to obscurity. A moving source, our Sun, can be seen arcing up and down the circles as it appears to move through the sky, a reflection of Earth’s annual orbital motion. Watch for strong flares that occasionally brighten the Sun. In these maps, brighter colors indicate greater numbers of gamma rays detected by Fermi’s Large Area Telescope from Aug. 10, 2008, to Aug. 2, 2022.

These visualizations show the Moon’s phase and libration at hourly intervals throughout 2024. Each frame represents one hour. In addition, the visualizations show the Moon’s orbit position, sub-Earth and subsolar points, and distance from the Earth at true scale. Craters near the terminator are labeled, as are Apollo landing sites, maria, and other albedo features in sunlight.

This sonification turns the orbits of a new seven-planet system, discovered by NASA’s retired Kepler space telescope, into sound. It begins at the center of the system with the innermost orbit and builds toward the outermost, introducing each orbit with a new sound that plays once per rotation around the central Sun-like star. It then focuses on two specific orbits in resonance, which creates a beating sound with the inner rotating twice in the same period as the outer rotates three times. Next, only the three outer-most planets are singled out as an orbital resonance chain before blending all seven together again. This is the first planetary system in which each planet bathed in more radiant heat from their host star per area than any in our solar system.

A new study using the now-retired Stratospheric Observatory for Infrared Astronomy (SOFIA) data has pieced together the first detailed, wide-area map of water distribution on the Moon. The new map covers about one-quarter of the Earth-facing side of the lunar surface below 60 degrees latitude and extends to the Moon’s South Pole. In this data visualization, SOFIA’s lunar water observations are indicated using color, with blue representing areas of higher water signal, and brown lower.
