The James Webb Space Telescope has observed Saturn for the first time, completing a family portrait of the Solar System\u2019s ringed planets nearly a year after the mission\u2019s first jaw-dropping image release.<\/p>\n

Webb\u2019s near-infrared camera took the picture of Saturn on June 25. Scientists added orange color to the monochrome picture to produce the image released Friday.<\/p>\n

The picture shows Saturn\u2019s iconic icy rings shining around the disk of the gas giant, which appears much darker in near-infrared due to the absorption of sunlight by methane particles suspended high in the planet\u2019s atmosphere.<\/p>\n

Webb pointed its 21.3-foot (6.5-meter) gold-coated mirror toward Saturn as part of an observing program to test the telescope\u2019s ability to detect faint moons. The observations included several deep exposures of Saturn that astronomers are still analyzing to probe the planet\u2019s fainter rings and search for undiscovered moons.<\/p>\n

There are 146 known moons in orbit around Saturn, ranging in size from larger than the planet Mercury to the size of a sports arena, more than any other planet in the solar system, according to NASA.<\/p>\n

\u201cAny newly discovered moons could help scientists put together a more complete picture of the current system of Saturn, as well as its past,\u201d NASA said in a blog post released with the new Saturn image.<\/p>\n

Three of Saturn\u2019s moons appear to the left of the planet in Webb\u2019s view: Dione, Enceladus, and Tethys are visible as points of light. Each is about the size of a large US state.<\/p>\n

Recent observations of Enceladus using Webb\u2019s near-infrared spectrograph instrument revealed a jet of water vapor extending more than 6,000 miles (10,000 kilometers) into space, 20 times the diameter of the moon. Scientists say Enceladus is one of the most promising locations in the solar system to search for signs of life because it harbors a water ocean underneath a global ice shell.<\/p>\n

NASA\u2019s Cassini orbiter flew by Enceladus numerous times before its mission ended in 2017. Cassini spotted similar water plumes erupting through fissures in Enceladus\u2019s ice sheet and flew through the jets to sample the particles coming from the moon\u2019s deep ocean.<\/p>\n

The Cassini spacecraft captured views of Saturn with higher resolution than Webb, but with Cassini\u2019s mission over, Webb is the primary tool scientists will use to continue studying Enceladus and Saturn for at least the next decade. <\/p>\n

There\u2019s currently no mission on the books to visit Enceladus. NASA\u2019s robotic Dragonfly mission is scheduled for launch toward Saturn in 2027, but it will focus on exploring Titan, Saturn\u2019s largest moon.<\/p>\n

The first scientific images from Webb were released nearly one year ago, showing the promise of the $10 billion mission to see deeper into the Universe than ever before. Observations within the Solar System are just part of Webb\u2019s scientific portfolio, alongside scientific topics such as studying the formation of the first galaxies after the Big Bang and the search for planets around other stars that might contain the ingredients for life.<\/p>\n

Webb science teams previously released spectacular views of the Solar System\u2019s other ringed planets\u2014Jupiter, Neptune, and Uranus\u2014along with its first observations of Mars.<\/p>\n

Stationed about a million miles from Earth, Webb is unable to observe the Moon, Mercury, or Venus because they are too bright or too close to the Sun.<\/p>\n","protected":false},"excerpt":{"rendered":"
