“Giant of ice”. So it is classified Neptune, the eighth and most distant planet in our solar system. And thanks to the new images made by James Webb Space Telescope, the largest and most powerful space telescope in operation, we better understand why. The image captured, the sharpest ever obtained, clearly shows the planet and the characteristic atmosphere that surrounds it, with temperatures up to -200 ° C. The Webb telescope image does not actually return the exact color of the planet, which should appear bluer. Neptune, in fact, was imaged in the infrared rather than in the visible light spectrum. A technique that slightly distorts the final color, but allows you to capture details that would otherwise be invisible. Neptune is the farthest planet of our solar system, located about 30 times farther from the Sun than the Earth. And it is precisely its position that condemns the planet to freezing temperatures, up to -200 degrees, and to a very long time of orbit around the sun: 164 Earth years. It is not the first time that the Webb telescope, the result of a collaboration between NASA, ESA and CSA (the Canadian space agency), generates unprecedented and so powerful images. Just a few weeks ago, the space telescope had immortalized tens of thousands of never-before-seen young stars. While in August, it was the turn of Jupiter, photographed for the first time in such a defined way as to show even the smallest details.
