EO Science Earth Observatory A Glimpse of History in Benin… Earth Earth Observatory Image of the Day More Subscribe   January 11, 2025 In some ways, Benin City is like dozens of other fast-growing cities in Nigeria. Buoyed by burgeoning industrial and agricultural sectors, the city’s population rose by 1.7 million people over the [...]

NASA/JPL-Caltech/Space Science Institute Dramatic plumes, both large and small, spray water ice out from many locations along the famed tiger stripes near the south pole of Saturn’s moon Enceladus in this image released on Feb. 23, 2010. A study published in October 2025 analyzed data from NASA’s Cassini mission and found evidence of previously undetected [...]

NASA’s nearly complete Nancy Grace Roman Space Telescope has made another set of critical strides toward launch. This fall, the outer portion passed two tests — a shake test and an intense sound blast — to ensure its successful launch. The inner portion of the observatory underwent a major 65-day thermal vacuum test, showing [...]

ESA/Webb, NASA & CSA, J. H. Kastner (Rochester Institute of Technology) Using its Near-InfraRed Camera (NIRCam), NASA’s James Webb Space Telescope captured never-before-seen details of the Red Spider Nebula, a planetary nebula, in this image released on Oct. 26, 2025. NIRCam is Webb’s primary near-infrared imager, providing high-resolution imaging and spectroscopy for a wide variety of investigations. [...]

NASA’s Lucy spacecraft captured images of the Moon’s surface on Oct 16, 2022, after flying by the Earth for its first of three gravity assists. Crater rims are vital landmarks for planetary science and navigation. Yet detecting them in real imagery is tough, with shadows, lighting shifts, and broken edges obscuring their shape. This project [...]
