James Webb Space Telescope captures image of Saturn

The astronomical library of images captured by the James Webb Space Telescope has now added Saturn to its card catalog.

NASA posted details about the image of the sixth planet from the sun captured by the telescope’s NIRCam instrument on June 25.

It shows the gas ball of the planet in dark orange and brown, but its rings lit up in the rendering of the planet that was monochrome, but color-enhanced with an orange hue to help illustrate the details of what was the space telescope’s first full near-infrared image of the planet.

The dark center is due to methane gas absorbing sunlight, while the icy rings stay bright along with three small dots visible to the left of the planet that are Saturn moons Dione, Enceladus and Tethys, according to NASA’s post.

Webb’s observations are part of an effort to look for new, faint moons around the planet and its rings.

About a decade ago, scientists knew of only 62 moons, but that number has as of May this year grown to 124, according to the NASA Solar System Exploration site. Its largest moon, Titan, is larger than both Mercury and Pluto. read more
