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 [...]
