Webb and Hubble deliver most detailed portrait of Saturn, revealing atmospheric layers and reflective rings

The NASA/ESA/CSA James Webb Space Telescope and NASA/ESA Hubble have combined infrared and visible-light observations to produce the most detailed portrait yet of Saturn. The images reveal atmospheric bands, layered storms and strikingly reflective rings, highlighting complementary capabilities across wavelengths.

JWST reveals widespread carbon dioxide on Europa, pointing to ocean–surface exchange James Webb Space Telescope spectra show carbon dioxide is far more widespread on Europa's surface than previously recognized, appearing in lens-like patches across multiple geologic terrains. The distribution implies active exchange processes between the moon's subsurface ocean and the ice shell, reshaping habitability assessments and mission targets.

JWST probes Uranus' ionosphere, maps vertical structure and detects faint auroras Uranus' extreme 97.8° axial tilt let JWST's NIRSpec probe the planet's ionosphere, producing the first vertical maps of its upper atmosphere and revealing faint auroral emissions. An international team used near‑infrared spectroscopy to resolve how temperature and charged‑particle densities change with altitude.

JWST Finds Most‑Distant Galaxy (MoM‑z14) at 280 Myr; Webb and Chandra See Cluster Assembling by ~1 Gyr JWST has detected MoM‑z14, the most distant galaxy yet observed, whose light dates to roughly 280 million years after the Big Bang. Combined JWST and Chandra data also show a galaxy cluster beginning to assemble about one billion years after the Big Bang, implying more rapid early structure growth.

James Webb reveals a new origin story for the universe’s first supermassive black holes James Webb Space Telescope observations provide new evidence about how the universe’s earliest supermassive black holes formed, tracing seeding and rapid-growth pathways within the first billion years. The results exploit JWST’s deep infrared reach to observe structures and processes from cosmic dawn.

JWST 'Little Red Dots' flagged as candidate nurseries for direct-collapse supermassive black holes JWST has detected compact sources dubbed 'Little Red Dots' that researchers say may be the first direct observational evidence of direct-collapse supermassive black hole formation. If confirmed, these objects would pinpoint the birth sites of the universe's most massive black holes and reshape early-galaxy assembly models.

JWST 'Little Red Dots' may be first direct evidence of early massive black-hole formation James Webb Space Telescope observations have uncovered compact, luminous 'Little Red Dots' that researchers say could represent the first direct observational evidence of the birth of the universe's most massive black holes. Teams interpret the sources as rapid accretion events — a potential early black‑hole 'feeding frenzy'.
