Mount Fuji From Orbit

Seen from the International Space Station, Japan’s Mount Fuji rises dramatically from the surrounding landscape. Low-angle sunlight emphasizes the volcano’s remarkably symmetrical cone, carving shadows into gullies along its flanks and into the summit crater and nearby Hoei crater.

At 3,776 meters (12,389 feet), Mount Fuji is Japan’s highest peak and one of the planet’s most recognizable volcanoes. Views like this from orbit offer a different perspective on the geologic processes that continually reshape Earth—our own dynamic world and the one against which we compare the landscapes and geology of other planets.

The Lion Nebula Roars

NASA’s JWST captured this striking new view of NGC 2392, nicknamed the Lion Nebula, using its near- and mid-infrared instruments. At its heart lies the remnant of a dying star, surrounded by material the star shed as it reached the final stages of its life.

JWST's high-resolution infrared vision brings remarkable detail to the nebula’s structure, revealing a bubble of ionized gas that resembles a lion’s face surrounded by a dramatic “mane” of gas and dust. Planetary nebulae like this one offer astronomers a glimpse of the distant future of stars similar to our Sun—and show how dying stars return material to space that can eventually become part of new stars and planets.

Curiosity Sees Martian Sulfur Up Close

Sometimes scientific discoveries happen by accident. NASA’s Curiosity rover uncovered these yellow sulfur crystals after driving over and crushing a rock on Mars in May 2024—the first time pure elemental sulfur had been found on the Red Planet.

Now, scientists may have an explanation for how it got there. A recent study suggests that magma deep beneath the Martian surface released fluids or gases that deposited sulfur near the surface about 3 billion years ago, adding another piece to the puzzle of Mars’ complex geologic past.

Falcon 9 Leaves Its Mark on the Moon

On August 5, 2026, a SpaceX Falcon 9 upper stage struck the Moon after drifting through the Earth-Moon system since launching Firefly Aerospace’s Blue Ghost 1 mission in January 2025. Six days later, NASA’s Lunar Reconnaissance Orbiter began photographing the impact site, revealing a fresh crater about 18 meters (60 feet) wide and less than 3 meters (10 feet) deep.

Bright and dark rays of debris extend outward from the crater, exposing material excavated from different depths beneath the lunar surface. Scientists are using the impact to study how collisions disturb the Moon’s regolith, while NASA’s Center for Near Earth Object Studies used the event to test techniques for predicting where objects will strike the lunar surface.

A Bubbling Betelgeuse

This remarkably detailed view of Betelgeuse, captured by the Atacama Large Millimeter/submillimeter Array (ALMA), reveals the uneven, bubbling surface of the famous red supergiant about 600 light-years away. Nearly 800 times larger than the Sun, Betelgeuse is covered by enormous regions of hot gas rising from deep within the star, creating the bright hotspots seen across its surface.

One of those hotspots has presented astronomers with a mystery: it appears in observations taken seven years apart, far longer than current models predict such features should survive. Understanding these enormous structures could offer new clues about the behavior of massive stars as they approach the final stages of their lives—and, eventually, explode as supernovae.
