The initial imagery from Webb’s NIRCam (Near-Infrared Camera) is already fascinating researchers. Saturn itself appears extremely dark at this infrared wavelength observed by the telescope, as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright, leading to the unusual appearance of Saturn in the Webb image. This image was taken as part of Webb Guaranteed Time Observation program 1247. The program included several very deep exposures of Saturn, which were designed to test the telescope’s capacity to detect faint moons around the planet and its bright rings. Details in the orbital characteristics of newly discovered moons could help scientists put together a more complete picture of the current system of Saturn, as well as its past. This new image of Saturn clearly shows details within the planet’s ring system, along with several of the planet’s moons – Dione, Enceladus, and Tethys. Additional deeper exposures (not shown here) will allow the team to probe some of the planet’s fainter rings, not visible in this image, including the thin G ring and the diffuse E ring. Saturn’s rings are made up of an array of rocky and icy fragments – the particles range in size from smaller than a grain of sand to a few as large as mountains on Earth. Researchers recently used Webb to explore Enceladus, and found a large plume jetting from the southern pole of the moon that contains both particles and plentiful amounts of water vapor – this plume feeds Saturn’s E ring. Saturn’s atmosphere also shows surprising and unexpected detail. This is the first time that the planet’s atmosphere has been seen with such clarity at this particular wavelength (3.23 microns). The large, dark, diffuse structures in the northern hemisphere do not follow the planehttps://roosnovo.com/wp-content/uploads/2024/12/saturn.jpgYet Another Storm on SaturnThis Hubble Space Telescope image of the ringed planet Saturn shows a rare storm that appears as a white arrowhead-shaped feature near the planet's equator. The storm is generated by an upwelling of warmer air, similar to a terrestrial thunderhead. The east-west extent of this storm is equal to the diameter of the Earth (about 12700 kilometres). Hubble provides new details about the effects of Saturn's prevailing winds on the storm. The new image shows that the storm's motion and size have changed little since its discovery in September, 1994.2026-02-18T02:55:43+00:00weekly0.6https://roosnovo.com/about/2025-11-19T00:35:09+00:00weekly0.6https://roosnovo.com/curriculum-vitae/https://roosnovo.com/wp-content/uploads/2024/12/rb4pygp6yhulcgnhmpdmvl.jpgRb4PYGp6YHULcGnhmpDMVL2025-08-17T17:59:15+00:00weekly0.6https://roosnovo.com/photography/bw/colorado2022/https://roosnovo.com/wp-content/uploads/2025/07/img_2851-1.jpegIMG_2851https://roosnovo.com/wp-content/uploads/2025/07/img_4348-1.jpegIMG_4348https://roosnovo.com/wp-content/uploads/2025/07/img_4343.jpegIMG_4343https://roosnovo.com/wp-content/uploads/2025/07/img_2862.jpegIMG_2862https://roosnovo.com/wp-content/uploads/2025/07/img_2853.jpegIMG_2853https://roosnovo.com/wp-content/uploads/2025/07/img_2867.jpegIMG_2867https://roosnovo.com/wp-content/uploads/2025/07/img_2850.jpegIMG_2850https://roosnovo.com/wp-content/uploads/2025/07/img_2861.jpegIMG_2861https://roosnovo.com/wp-content/uploads/2025/07/img_2857.jpegIMG_2857https://roosnovo.com/wp-content/uploads/2025/07/img_2851.jpegIMG_28512025-07-25T20:46:27+00:00weekly0.6https://roosnovo.com/photography/bw/arizona2024/2025-07-25T20:45:52+00:00weekly0.6https://roosnovo.com/photography/bw/italy2022/https://roosnovo.com/wp-content/uploads/2025/07/img_2865crop.jpegIMG_2865crophttps://roosnovo.com/wp-content/uploads/2025/07/img_2877crop.jpegIMG_2877crophttps://roosnovo.com/wp-content/uploads/2025/07/img_2878-2.jpegIMG_2878https://roosnovo.com/wp-content/uploads/2025/07/img_2852-2.jpegIMG_2852https://roosnovo.com/wp-content/uploads/2025/07/img_2878-1.jpegIMG_2878https://roosnovo.com/wp-content/uploads/2025/07/img_2865-1.jpegIMG_2865https://roosnovo.com/wp-content/uploads/2025/07/img_2871-1.jpegIMG_2871https://roosnovo.com/wp-content/uploads/2025/07/img_2852-1.jpegIMG_2852https://roosnovo.com/wp-content/uploads/2025/07/img_2877-2.jpegIMG_2877https://roosnovo.com/wp-content/uploads/2025/07/img_2849-2.jpegIMG_28492025-07-25T20:41:44+00:00weekly0.6https://roosnovo.com/photography/bw/coloradonewmexico2022/2025-07-25T20:41:13+00:00weekly0.6https://roosnovo.com/photography/bw/2025-07-25T20:35:45+00:00weekly0.6https://roosnovo.com/photography/2025-07-25T20:32:26+00:00weekly0.6https://roosnovo.comdaily1.02026-02-18T17:09:12+00:00
