Neptune, the last planet in the solar system, was revealed in infrared by James-Webb. The most advanced space telescope ever launched gives us a rare picture of the ice giant’s rings. An intriguing moon, Triton appears brighter than Neptune.
After the remarkable film Thursday This summer, tuesday A few days ago, there is a third planet here solar systemsolar system aiming at The telescopeThe telescope James-Webb, Farthest of all: Neptune.

The first of these are his rings. The AstronomersAstronomers They are once again amazed by the space telescope’s ability to identify the most obscured and faintest parts of a celestial object. In the case of the ice giant, the rings were best seen in 1989 when the Voyager 2 spacecraft visited. You can see many moons, like Galatea, with very thin, accompanying dust rings. and Despina. If you look closely, another ring will appear near the planet.
Interesting colors of Neptune
In these images, the planet itself appears to glow like a disco ball in the evening, especially at its peak latitudeslatitudes and to the poles. Active areas are more reflective than these the lightthe light from SoleilSoleil than the restthe atmospherethe atmosphere Neptune’s is more homogeneous and darker due to absorption of methane.
Another detail that has not escaped researchers is the presence of edges the edgesthe edges White, including one very delicateEquatorEquatorNo doubt will be betrayed Atmospheric circulationAtmospheric circulationAs explained in NASANASA.

Other, smaller moons you’ve never heard of can also be seen in this image. There are seven of the 14 known: Triton, and therefore, within Neptune’s rings, Galatea, Naiad, Thalassa, Despina, and finally Larissa.
