However, it's also using its stable and precise image quality to illuminate our own solar system, with images of Mars, Jupiter and now Neptune. Webb is a more than 10-year mission run by NASA, the European Space Agency and the Canadian Space Agency.Ĭompared with other telescopes, the space observatory's massive mirror can see fainter galaxies that are farther away and has the potential to enhance scientists' understanding of the origins of the universe. At that distance, the sun is so small and faint that noon on Neptune is similar to a dim twilight on Earth, the news release said. Located 30 times farther from the sun than Earth, Neptune moves through its solar orbit in the remote, dark region of the outer solar system. Scientists plan to use Webb to further study Triton and Neptune in the coming years. Astronomers think Triton was perhaps an object in the Kuiper Belt - a region of icy objects at the edge of the solar system - that fell into Neptune's gravitational grasp. Webb also captured seven of Neptune's 14 known moons, including its largest moon, Triton, which moves around the planet at an unusual backward orbit.
It's also possible to spot a bright, thin line circling the planet's equator, which could be "a visual signature of global atmospheric circulation that powers Neptune's winds and storms," according to the release.
This is because gaseous methane, part of the planet's chemical makeup, doesn't appear blue to Webb's Near-Infrared Camera (NIRCam).Īlso visible in the images are methane-ice clouds - bright streaks and spots that reflect sunlight before it is absorbed by methane gas. In the new images, Neptune looks white, as opposed to the typical blue appearance it has in views captured at visible wavelengths of light. The planet and its neighbor Uranus are known as "ice giants" because their interiors are made up of heavier elements than the gas giants Jupiter and Saturn, which are richer in hydrogen and helium. Some of the rings haven't been observed since NASA's Voyager 2 got the first photographic proof of the existence of Neptune's rings during its flyby in 1989, CNN reported.ĭark, cold and whipped by supersonic winds, Neptune is the most distant planet in our solar system. In addition to several crisp, narrow rings, the Webb images show Neptune's fainter dust bands. "It has been three decades since we last saw these faint, dusty rings, and this is the first time we've seen them in the infrared," said Heidi Hammel, a Neptune expert and interdisciplinary scientist on the Webb project, in a news release. New images released Wednesday from NASA's James Webb Space Telescope are revealing Neptune, and the planet's hard-to-detect rings, in a fresh light.

The ESA Webb statement revealed: “A previously-known vortex at the southern pole is evident in Webb’s view, but for the first time Webb has revealed a continuous band of clouds surrounding it." Automate and standardize as your modeling team grows. Thanks to the precision and stability of the James Webb Telescope, scientists can see Neptune in greater detail than ever before with the telescope's infrared sensitivity.

At that extreme distance, the Sun is so small and faint that high noon on Neptune is similar to a dim twilight on Earth.” Located 30 times farther from the Sun than Earth, Neptune orbits in one of the dimmest areas of our Solar System.
Neptune is the furthest planet from our central star at approximately 2.8 billion miles (4.5 billion kilometres) away, showing just how impressive the telescope is.Īn ESA Webb statement explained: "Neptune has fascinated and perplexed researchers since its discovery in 1846. Neptune’s rings have not been captured with such clarity since the Voyager 2 flyby over 30 years ago.īy comparison, Voyager 2 flew around 3,000 miles (4,950 kilometres) above Neptune's north pole but the James Webb telescope orbits the Sun. The telescope images show the mysterious icy planet’s bright rings as well as dust bands which are fainter and rarely seen. This new image brings it closer to home with the clearest view of planet Neptune and its rings since 1989. Since its first images in July, the James Webb Space Telescope has been revealing stunning images of nebulas and stars.
