The James Webb Space Telescope captures extremely clear images of Neptune and its rings

Read Time:5 Minute, 43 Second

So far, the James Webb Space Telescope has given us some insanely detailed images of deep space, giving us insight into the early days of the universe. But now his well-tuned lenses look a little closer to us, and the results are impressive. These are infrared pictures of Mars taken by the James Webb telescope, which show the red planet in yellow and purple. So, for the layman, what exactly are we seeing here? *** much of the infrared information received from the planet is *** the result of thermal radiation from it. So basically info, but you may notice the *** darker orange area at the bottom of the image. This is the Hellas basin, and not only is it one of the largest craters caused by a *** massive object hitting Mars, it is also one of the largest impact craters in the entire solar system. So what does the color change tell us? The darker area shows that the Martian atmosphere, which is mostly carbon dioxide, is thicker around the crater. And the researchers say that this single snapshot allowed us to predict the presence of not only carbon dioxide, but also carbon monoxide and water in the Martian atmosphere.

Video above: The James Webb Space Telescope takes unexpected pictures of Mars. New images released Wednesday from NASA’s James Webb Space Telescope show Neptune and the planet’s elusive rings in fresh light. “It’s been three decades since we last saw these faint dust rings, and this is the first time we’ve seen them in the infrared,” Heidi Hummel, a Neptune expert and interdisciplinary project scientist for the Webb project, said in a press release. release. In addition to several distinct, narrow rings, Webb’s images show fainter dust lanes on Neptune. Some of the rings have not been observed since NASA’s Voyager 2 obtained the first photographic evidence of Neptune’s rings during a flyby of Neptune in 1989. Dark, cold and whipped by supersonic winds, Neptune is the most distant planet in our solar system. The planet and its neighbor Uranus are known as “ice giants” because their interior is made up of heavier elements than the gas giants Jupiter and Saturn, which are richer in hydrogen and helium. In the new images, Neptune appears white, in contrast to the typical blue appearance it has in views taken in the visible wavelength range of light. This is because methane gas, which is part of the planet’s chemical composition, does not appear blue to Webb’s Near Infrared Camera (NIRCam). Also visible in the images are methane-ice clouds – bright streaks and spots that reflect sunlight before it is absorbed by the methane gas. A bright thin line can also be seen encircling the planet’s equator, which may be “a visual sign of the global atmospheric circulation that powers Neptune’s winds and storms.” Webb also captured seven of Neptune’s 14 known moons, including its largest moon, Triton, which orbits the planet in an unusual retrograde orbit. Astronomers believe that Triton may have been an object in the Kuiper Belt – a region of icy objects at the edge of the Solar System – that fell into Neptune’s gravitational grip. Scientists plan to use Webb to further study Triton and Neptune in the coming years. Located 30 times farther from the Sun than Earth, Neptune moves in its solar orbit in a distant dark region of the outer Solar System. At this distance, the sun is so small and faint that noon on Neptune is similar to dim twilight on Earth, according to a press release. Webb is a more than 10-year mission carried out by NASA, the European Space Agency and the Canadian Space Agency. Compared to other telescopes, the space observatory’s huge mirror can see fainter galaxies that are further away and could improve scientists’ understanding of the origin of the universe. However, it also uses its stable and accurate image quality to illuminate our own solar system with images of Mars, Jupiter and now Neptune.

“It’s 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 Hummel, a Neptune expert and interdisciplinary Webb project scientist. in a news release.

In addition to several distinct, narrow rings, Webb’s images show fainter dust lanes on Neptune. Some of the rings have not been observed since NASA’s Voyager 2 captured the first photographic evidence of Neptune’s rings during a flyby in 1989.

Dark, cold and whipped by supersonic winds, Neptune is the most distant planet in our solar system. The planet and its neighbor Uranus are known as “ice giants” because their interior is made up of heavier elements than the gas giants Jupiter and Saturn, which are richer in hydrogen and helium.

In the new images, Neptune appears white, as opposed to the typical blue appearance it has in views taken in visible light wavelengths. This is because methane gas, which is part of the planet’s chemical composition, does not appear blue to Webb’s Near Infrared Camera (NIRCam).

Also visible in the images are methane ice clouds – bright streaks and spots that reflect sunlight before it is absorbed by the methane.

Webb is a more than 10-year mission led by NASA, the European Space Agency and the Canadian Space Agency.
