The full view of the James Webb Space Telescope’s NIRCam (Near-Infrared Camera) instrument reveals a 50 light-years-wide portion of the Milky Way’s dense center. An estimated 500,000 stars shine in this image of the Sagittarius C region, along with some as-yet unidentified features. A vast region of ionized hydrogen, shown in cyan, wraps around an infrared-dark cloud, which is so dense that it blocks the light from distant stars behind it. Intriguing needle-like structures in the ionized hydrogen emission lack any uniform orientation. Researchers note the surprising extent of the ionized region, covering about 25 light-years.

UNCOVER z-13 and UNCOVER z-12 are the second and fourth most distant galaxy ever observed. The James Webb Space Telescope’s Near-Infrared Camera (NIRCam) helped confirm their existence within Pandora’s Cluster (Abell 2744). They are shown here as near-infrared wavelengths of light that have been translated to visible-light colors.

Space Telescope with visible-light data from NASA’s Hubble Space Telescope. The resulting wavelength coverage, from 0.4 to 5 microns, reveals a vivid landscape of galaxies whose colors give clues to galaxy distances: The bluest galaxies are relatively nearby and often show intense star formation, as best detected by Hubble, while the redder galaxies tend to be more distant, or else contain copious amount of dust, as detected by JWST.

This square astronomical image is divided horizontally by a waving line between a white-orange cloudscape forming a nebula along the bottom portion and a comparatively blue-purple-pink upper portion. From the nebula in the bottom half of the image, an orange cloud shaped like a horsehead sticks out. In the bottom left of the image, a white round glow is visible. The clouds from the bottom half of the image shine purple/blue light into the upper half. The top of the image shows the black expanse of space. Speckled across both portions is a starfield, showing stars of varying sizes and colors. Blue stars are younger and red stars are older.

Astronomers found the most distant black hole ever detected in X-rays (in a galaxy dubbed UHZ1) using the Chandra X-Ray Observatory and the James Webb Space Telescope. X-ray emission is a telltale signature of a growing supermassive black hole. This result may explain how some of the first supermassive black holes in the universe formed. These images show the galaxy cluster Abell 2744 that UHZ1 is located behind, in X-rays from Chandra and infrared data from JWST, as well as close-ups of the black hole host galaxy UHZ1.

A sample of Asteroid Bennu is put on public display for the first time at the Museum of Natural History in Washington, DC, on November 3, 2023. A sample collected from the 4.5-billion-year-old asteroid Bennu contains abundant water and carbon, NASA revealed, offering more evidence for the theory that life on Earth was seeded from outer space. The small black rock is located in a glass viewing pain.

A large asteroid with a smaller asteroid orbiting it. This image shows the “moonrise” of the satellite as it emerges from behind asteroid Dinkinesh as seen by the Lucy Long-Range Reconnaissance Imager. This image was taken by NASA’s Lucy spacecraft at 12:55 p.m. EDT on November 1, 2023, within a minute of closest approach, from a range of approximately 270 miles. From this perspective, the satellite is behind the primary asteroid. The image has been sharpened and processed to enhance contrast.

An image of Jupiter taken with the James Webb Space Telescope’s NIR Cam in July 2022. Researchers recently discovered a narrow jet stream traveling 320 miles per hour sitting over Jupiter’s equator above the main cloud decks. The numerous bright white "spots" and "streaks" are likely very high-altitude cloud tops of condensed convective storms. Auroras, appearing in red in this image, extend to higher altitudes above both the northern and southern poles of the planet.

This new infrared image of NGC 346 from NASA’s James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) traces emission from cool gas and dust. In this image blue represents silicates and sooty chemical molecules known as polycyclic aromatic hydrocarbons, or PAHs. More diffuse red emission shines from warm dust heated by the brightest and most massive stars in the heart of the region. Bright patches and filaments mark areas with abundant numbers of protostars.

The center of the image – representing an area within the orbit of Jupiter – is very densely packed with orbits, while the outer edges remain clearer, showing the background plane of the Milky Way.
