Webb’s NIRCam image of Neptune on July 12 brought the planet’s rings into focus for the first time in more than three decades, the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) said.

“It’s been three decades since we’ve seen these faint dust rings, and this is the first time we’ve seen them in infrared light,” said CNN Neptune expert and interdisciplinary telescope scientist Heidi Hammel. Webb.

Voyager 2 captured these planetary rings in similar detail when it flew over Neptune in 1989. Scientists note that some of them have not been seen at all, let alone with such clarity, since Voyager’s flyby.

In short, the photographic equipment of the Webb telescope reveals the planet Neptune in a new light, astronomers rejoice.
Webb focused on the “nearby” Tarantula Nebula and revealed unknown stars

The most prominent features of Neptune’s atmosphere in the image are a series of bright spots in the planet’s southern hemisphere, representing high-altitude methane ice clouds. A thin band of brightness orbiting the equator could be a “visual signature” of the global atmospheric circulation that drives Neptune’s winds and storms. Additionally, Webb first discovered a continuous band of clouds surrounding the formerly known vortex at the South Pole.

JWST also recorded the moons of this ice giant.

Neptune in a new light! 🔵
Hubble’s view of this planet looks quite different from @NASAWebbIt’s the new image, right.
This is because these two telescopes observed the planet with different wavelengths of light. ⬇️ pic.twitter.com/omelj0ZkDX

Small inconvenience
As cosmonautics specialist Michal Václavík of the Czech Space Agency and the Faculty of Mechanical Engineering of the Czech Technical University in Prague pointed out on his Twitter, the MIRI instrument on the telescope is now malfunctioning.

The JWST MIRI tool was not working correctly. The mechanism of one of the diffraction grating wheels showed increased friction during movement. Until the end of the investigation, its use was suspended. Thus, perhaps only temporarily, MIRI lost one of his ways of working (it is MRS). pic.twitter.com/DWUbl5fW55
