ALT A full disk image of Earth, as seen from the Orion capsule. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. From about 8 to 9 o'clock, a large brown landmass is Africa, with the Iberian peninsula twinkling with lights just where the planet curves. At the 1 o'clock spot, aurora glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space. Credit: NASA/Reid Wiseman
ALT A colorful, painterly image of the gas and stars of Messier 17. The scene is split in two diagonally across the middle by different types of dust—a bright turquoise on the top-left half, and billows of ochre cascading down the bottom right half. Red stars are speckled about the scene. Credit: ESA, NASA, and J. Hester (Arizona State University)
ALT An image from NASA’s Hubble Space Telescope showing the interstellar comet 3I/ATLAS. The comet is a small white dot in the center of the image, with a light blue halo of light that takes up most of the image. Other stars are shown streaking across the image as diagonal blue-white lines.
ALT On a dark background, interstellar comet 3I/ATLAS appears as a pale smudge with a whitish core. A cloud of haze extends slightly from the comet toward the bottom left of the image and, to a lesser extent, toward the right side of the image. The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter captured this image on Oct. 2, 2025. Credit: NASA/JPL-Caltech/University of Arizona
