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. 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. 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. Any newly discovered moons could help scientists put together a more complete picture of the current system of Saturn, as well as its past. 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. This image was taken as part of Webb Guaranteed Time Observation program 1247. However, the icy rings stay relatively bright, leading to the unusual appearance of Saturn in the Webb image. 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. The initial imagery from Webb’s NIRCam (Near-Infrared Camera) is already fascinating researchers. On June 25, 2023, NASA’s James Webb Space Telescope turned to famed ringed world Saturn for its first near-infrared observations of the planet.

In this monochrome image, NIRCam filter F323N (3.23 microns) was color mapped with an orange hue. Image of Saturn and some of its moons, captured by the James Webb Space Telescope’s NIRCam instrument on June 25, 2023. Each event will be different, but all will highlight Webb science and accomplishments with information, activities, or a presentation.Įditor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. These free, public events will be held at schools, libraries, museums, and other community locations in 25 states and Washington, D.C., in July, August, and September. Throughout the summer, locations around the country are hosting Webb Community Events to celebrate the Webb anniversary.
Webb Anniversary Community Events, Nationwide There will be talks about Webb, a Virtual Reality experience, hands-on activities for children, and educational giveaway items. Visitors of all ages can learn about the telescope and how it studies the universe with its infrared eyes.
