He telescope james webb space from NASA Gained a never-before-seen perspective on the rings of Saturn through the system NIRCam (Near infrared camera).
In the image you can see Saturn muchor darker at this wavelength infrared, since the methane gas that surrounds it absorbs almost all the sunlight that reaches its atmosphere. However, the rings of the planet with show brightwhich reveals a photograph of Saturn quite unusual thanks to James Webb.

It was taken as part of an observation program commissioned to test the ability of the Webb to detect several of the cure ‘weak‘ that surround the planet and its huge rings shiny. The discovery of other moons could help scientists model a much more complete picture of the current system of Saturn and thus answer questions from his past.
The photograph shows Saturn with evident light details in its ring system, in addition to several curebetween them Dione, Enceladus y Thetis. The research team also captured some other ‘deeper additional exposures’, which will allow them to notice other rings of Saturn that are not as visible, including the G and E ring

Most of the rings of Saturn Are composed of fragments of roca y ice. Its particles vary in size; from a grain of sand to the size of any mountain on Earth.
The researchers also analyzed the moon enceladuswhere they found a ‘gran plume‘ which comes from the south pole of the Moon and which ccontains water vapor particles; same plume that feeds the Saturn’s E ringaccording to NASA.
this is also the first time the planet’s atmosphere is visible at this wavelengthexclusive of Webb. Large, dark, fuzzy features in the Northern Hemisphere do not follow the planet’s lines of latitude, so this image lacks the familiar streaky appearance typically seen from Earth’s deeper atmospheric layers. Saturn.
When comparing the north and south poles of the planet in this image, the differences in appearance are typical of the known seasonal changes in Saturn. For example, the planet is currently experiencing northern summer, with the southern hemisphere ending winter.
The telescope Webb will keep watching the Saturn for future research and to deepen the data obtained.
