Description These observations by NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) show the infrared light emitted by the dust, water, organic molecules, and carbon dioxide contained within comet 3I/ATLAS’s coma. The comet brightened significantly during the December 2025 period when SPHEREx made the observations — about two […]

Visualizing Perseverance’s AI-Planned Drive on Mars
Description This animation of NASA’s Perseverance was created with the Caspian visualization tool using data acquired during an 807-foot (246-meter) drive on the rim of Jezero Crater made by the rover on Dec. 10, 2025, the 1,709th Martian day, or sol, of the mission. The mission’s “drivers,” or rover planners, use the information to understand the Perseverance’s […]
Video: Perseverance Rover’s View of Crater Rim Drive
Description This animation shows Perseverance’s point of view during drive of 807 feet (246 meters) along the rim of Jezero Crater on Dec. 10, 2025, the 1,709th Martian day, or sol, of the mission. Captured over two hours and 35 minutes, 53 Navigation Camera (Navcam) image pairs were combined with rover data on orientation, wheel speed, […]
Mapping Perseverance’s Route With AI
Description This annotated image from NASA’s HiRISE (High Resolution Imaging Science Experiment) camera aboard the agency’s Mars Reconnaissance Orbiter image depicts the AI-planned route and the actual route taken by NASA’s Perseverance Mars rover during its 807-foot (246-meter) drive on Dec. 10, 2025, the 1,709th Martian day, or sol, of the mission. The drive was the second of two demonstrations […]
NASA Analysis Shows La Niña Limited Sea Level Rise in 2025
Description This graph shows the rise in global mean sea level from 1993 to 2025 based on data from a series of five international satellites. The solid red line indicates the trajectory of this increase, which has more than doubled over the three decades. The dotted red line projects future sea level rise. A NASA analysis […]
Europa’s Ice Shell (Artist’s Concept)
Description This artist’s concept depicts a cutaway view showing Europa’s ice shell. It contains a shallow layer of small imperfections (cracks, pores, and voids) that extend down from the surface hundreds of feet. The icy moon of Jupiter is thought to harbor an ocean below its frozen exterior. Data used to generate a new result […]
Webb Data Reveals Dark Matter
This image from NASA’s James Webb Space Telescope, containing nearly 800,000 galaxies, is overlaid with a map of dark matter, represented in blue. Brighter blue areas indicate a higher density of dark matter. Researchers used Webb data to find the dark matter — which is invisible — via its gravitational influence on regular matter. The […]
Europa Clipper Captures Uranus With Star Tracker Camera
Description NASA’s Europa Clipper captured this image of a starfield — and the planet Uranus — on Nov. 5, 2025, while experimenting with one of its two stellar reference units. These star-tracking cameras are used for maintaining spacecraft orientation. Within the camera’s field of view — representing 0.1% of the full sky around the spacecraft […]
