And now Jupiter in the eyes of the James-Webb Space Telescope

The James Webb Space Telescope not only examines celestial objects millions or billions of light-years away, it also focuses on the large mirror of Jupiter and the possible habitat of the moon, the Europe. Once again, the result exceeded astronomers ’expectations.

the first photographs by James-Webb opened on July 12, and effectively inaugurated the scientific campaign of the largest and most powerful space telescope ever launched, amazed us with their discoveries on Tuesday. There is so much to say about each of them, from the farthest part ofuniverse again and the deepest image of the Universe ever captured » -, sa planetary nebula from the southern ring, passing through a nebula with startling “reliefs” of details, and not to mention the intertwined galaxies of Stefan’s Quintet, which one can even see. star individual … In short, iconic images. An impressive leap forward in the details captured by its instruments for cosmic objects tens of thousands of miles away.light years… a few billion light-years away. and “This is just the beginning! » (this is only the beginning), is repeated astrophysicists who participated in their live presentations at Nasa.

And now, Jupiter!

Another surprise and beauty registered on July 12 in the Mikulski archive of STSI (Space Telescope Science Institute) as part of the James-Webb commissioning, a familiar and close object: Jupiter. the astronomers pleased and did not hide their admiration for the quality of the images and data obtained.

Interested to see what it would be like to look at a close and bright celestial body, they did not disappoint: these pictures of the largest planet in Solar system actually reveals his very clever rings (pictured by NIRCam), the moon Europe and the little Metis and Thebes. “Images of Jupiter in narrowband filters are designed to provide beautiful images of the entire planetary disk, but a wealth of additional information about more fragile objects (Métis, Thebes, the main ring, the fogs) of these images taken with about a minute of exposure was a pleasant surprise ”said John Stansberry, who takes care of the NIRCam instrument.

As far as it is concerned Europeone of Jupiter’s four Galilean satellites (visible with binoculars), we can also see its shadow pointed at Jupiter, just to the left of the famous Big Red Dot. This potentially habitable satellite sheltering the entire world’s oceans under thick ice mud could be a privileged target for astronomers hoping to explore and study it. feathers of water vapor with a space telescope. “I think that’s just one of the coolest things we can do with this telescope in the solar system.”said Stefanie Milam, planetary sciences researcher at GSFC (Goddard Space Flight Center) from NASA.

James Webb it is not yet finished to amaze us and the scientific images of the Universe will rain down for our greatest delight, showing us structures and objects we have never seen before.
