Saturn’s atmosphere revealed: Webb and Hubble unveil hidden motions under the clouds

Two space telescopes, Webb and Hubble, captured Saturn in complementary wavelengths— Webb's infrared reveals deep atmospheric structures like the 'ribbon wave' and remnants of the Great Springtime Storm, while Hubble shows visible bands and seasonal shifts. Together they let scientists slice Saturn's atmosphere layer by layer, study fast-moving winds and energy transport, and observe the enduring hexagon at the north pole as Saturn heads into winter.

Dual Space Telescopes Unveil Multilayer Portrait of Saturn's Turbulent Atmosphere

Two decades-spanning observations from JWST (infrared) and Hubble (visible) provide the most comprehensive, height-resolved view of Saturn to date, capturing the iconic north-polar hexagon and the infrared glow of its rings while revealing how Saturn’s winds and megastorms vary with altitude. The data help scientists understand the planet’s atmospheric dynamics and evolution, with the north pole about to enter 15 years of winter darkness, limiting future high‑resolution views until the 2040s.

Hubble captures 25-year evolution of the Crab Nebula

Astronomers compared two high-resolution Hubble images of the Crab Nebula taken in 1999/2000 and 2024, finding the iconic supernova remnant has expanded and changed shape over 25 years. The nebula’s filaments are moving outward at about 3.4 million mph, driven by energy from the central pulsar rather than a passing shock wave, and the new view reveals 3D structure and varying gas temperatures within the expanding shell.

Saturn Revealed in High Definition by Hubble and Webb

NASA’s joint observations from the Hubble and James Webb Space Telescopes deliver the most detailed, multi-wavelength portrait of Saturn to date, revealing a layered atmosphere and intricate ring structures by combining visible and infrared data to visualize atmospheric layers, jet streams, and seasonal changes as Saturn approaches its 2025 equinox.

Hubble records comet’s spin flip as jets reverse its rotation

NASA’s Hubble Space Telescope tracked comet 41P/Tuttle–Giacobini–Kresák and observed its rotation reverse due to jets of gas and dust, with the spin slowing between 2017 observations and then flipping to a much faster rate (about 14 hours) by December 2017. Scientist David Jewitt explains that uneven jets act like tiny thrusters, reversing the comet’s spin, an unprecedented finding that may signal structural changes or breakup; the results were published in The Astronomical Journal.

Saturn Reimagined: Webb and Hubble Collaborate for a Multi-Wavelength Portrait

NASA released a new composite portrait of Saturn created by combining infrared data from the James Webb Space Telescope with visible/ultraviolet data from the Hubble Space Telescope, producing a layered, multi‑wavelength view that reveals Saturn’s atmospheric structure, jets, storms, potential auroral activity, and detailed ring features—showing how merging observations from multiple telescopes yields a fuller understanding of the planet’s dynamic climate and rings.

Webb and Hubble Spotlight Saturn in Infrared: Rings, Moons, and the Polar Hexagon

Webb’s infrared images of Saturn, paired with Hubble’s visible-light data, show bright rings, a multi-layer atmosphere, and weather patterns, plus moons Janus, Dione and Enceladus; Enceladus’s plumes hint at a subsurface ocean, while the iconic north-polar hexagon remains visible as Saturn heads toward its 2025 equinox, with sharper views anticipated into the 2040s.

Hubble Detects an Almost Invisible Galaxy That’s 99.9% Dark Matter

Astronomers using the Hubble Space Telescope (with Euclid and Subaru) identified CDG-2 in the Perseus Cluster, a 300-million-light-year‑away galaxy that appears almost entirely devoid of stars; the object is estimated to be 99.9% dark matter, kept together by a halo and four globular clusters after nearby galaxies stripped away its star-forming material, making it a rare, near-pristine laboratory for studying dark matter.

Hubble’s Fresh View Reveals Dynamic Crab Nebula Filaments

Hubble released a new image of the Crab Nebula, the remnant of a supernova observed in 1054 A.D., showing that its outer gas filaments have evolved and are moving faster than the inner regions over the past 25 years, a motion driven by the nebula’s central pulsar.

Webb and Hubble Team Up for a Layered Portrait of Saturn

NASA, ESA and CSA released new Saturn images from the James Webb Space Telescope and Hubble that reveal different atmospheric layers: Hubble’s visible-light photos show color bands and storms, while Webb’s infrared view highlights deep clouds, aerosols, and the rings’ ice; taken in Aug 2024 (Hubble) and a few months later (Webb), the pair helps scientists study Saturn’s atmosphere across depths and track seasonal changes as it moves toward the 2025 equinox, with future observations promising even clearer southern-hemisphere views.

Webb and Hubble Deliver a Multi-Layer Portrait of Saturn

NASA's James Webb Space Telescope (JWST) and the Hubble Space Telescope released complementary views of Saturn in infrared and visible light, revealing a dynamic atmosphere, bright rings, and several moons. The multi-wavelength approach lets scientists probe different atmospheric depths, effectively slicing Saturn's atmosphere by altitude. Webb highlights features like the long-lived northern ribbon wave and remnants of the Great Springtime Storm (2010–12), while Hubble shows color variations and ring shadows. Captured about 14 weeks apart in late 2024 as part of ongoing monitoring (including Cassini-era data and the OPAL program), the observations extend Saturn’s atmospheric record and demonstrate Webb’s infrared capabilities alongside Hubble’s view, in an international NASA/ESA/CSA collaboration.

Hubble Revisits Crab Nebula, Revealing Evolving Gas Clouds After 25 Years

NASA’s Hubble Space Telescope released new 2024 images of the Crab Nebula (Messier 1), taken 25 years after the initial look, showing moving gas clouds and changes in temperature, density, and chemistry as the remnant continues to expand (about 3.4 million mph) from its 1054 supernova, located roughly 6,500 light-years away in Taurus.

Hubble clocks a quarter-century of Crab Nebula expansion in sharper detail

The Hubble Space Telescope revisits the Crab Nebula, 6,500 light-years away, to trace 25 years of expansion. The new high-resolution images show peripheral filaments moving outward at about 5.5 million kilometers per hour and reveal a more detailed 3D structure, with color and brightness changes tied to local temperature, density, and composition. The study, comparing with the 1999 data and complemented by multiwavelength work including Webb’s 2024 infrared observations, will help scientists better understand the ongoing aftermath of the SN 1054 explosion. The findings are published in The Astrophysical Journal.

Hubble Sees Comet ATLAS Split into Four Fragments

NASA/ESA’s Hubble Space Telescope captured comet C/2025 K1 (ATLAS) breaking into four fragments just after its perihelion, each surrounded by its own coma. The near-simultaneous breakup provides a rare, nearly pristine sample to study the comet’s composition and the physics of fragmentation and dust-layer formation, offering insights into how icy bodies evolve in the solar system. Observations were made in early November 2025 from about 250 million miles away, and scientists highlighted the serendipitous timing as a reminder that unexpected results can drive breakthrough science.

Hubble Traces a Quarter-Century of Crab Nebula Expansion

NASA's Hubble Space Telescope revisited the Crab Nebula, producing a 2024 image that, when paired with 1999 data, reveals the remnant's 25-year expansion and evolving filaments driven by the central pulsar wind. The study shows outward motion of filaments at about 3.4 million miles per hour and highlights how Hubble's longevity and upgraded instruments enable detailed 3D insights when combined with multiwavelength observations, including JWST, with findings published in The Astrophysical Journal.
