[EN VIDÉO] Understand the James Webb Space Telescope mission in one minute
The James Webb Space Telescope, a new flagship in space observation, will be launched from Cairo, Guyana on 18 December. After a 29-day journey, it will reach Lagrange Point L2, opposite the Sun. Larger than its mirror Hubble, in which it is considered a successor, JWST will be able to observe galaxies, planets, nebulae and stars to learn more about the history of the universe.

Will have to wait another 12 days. July 12, NASA, theESA And the CSA (Canadian Space Agency) will release the first image as well as the first spectroscopic data from the James-Web Space Observatory.

NASA boss Bill Nelson stressed at a news conference yesterday that one of the images unveiled is our deepest image. The world Which was never achieved. ” This is more than mankind has ever seen before “He is declared and qualified Telescope Of ” Nothing less than a true scientific achievement “This image will therefore transcend that of the ultra-deep fieldHubble, Which has become iconic. For now, it is not known if James-Webb observed the same point from the region as Hubble.Southern HemisphereLocated Constellations Reactor

Pictures to change the vision of astronomy

The images that will be made public have been selected NASA says they have been selected for their scientific considerations, their ability to demonstrate the power of telescopes, and their artistic interest and expected color beauty. Will publish each image ” Different aspects of the universe Infrared In unprecedented detail and sensitivity Says James-Webb scientists.

In addition to its deepest infrared view Cosmos To this day, images will also show how galaxies interact and grow. They can also show They The dying plant sows the seeds of the galaxy with new material and dust that may one day become part of the new planetary system. Will James-Webb reunite with celebrities? Nebula de l’Aigle (M 16) and its iconic Pillars of Creation? We suspect that NASA did not. ” Tease. Pictures that will be made public …

About spectroscopic data, in Spectrum Acquired, that figureAtmosphere Of one Exoplanet Don’t be confused with “living” if any molecule exists in the atmosphere of what can help us identify and whether the observed exoplanets could potentially be habitable.

At the conclusion of this press conference, everyone is convinced that James Webb must revolutionize astronomy and answer many questions, such as ” Where do we come from? “,” Who are we? “And” What else is there? A

Other good news: We knew that, thank you 5 in AriadneJames Webb Will work longer than expected, 5 years as opposed to 10 years initially planned. Finally, fine calculations show that it had enough fuel to run for at least 20 years.

Remember the date! The first “real” picture of James-Webb will be published soon

Humanity is going to be amazed at the next vision given by the James-Webb Telescope, which is basically what astronomers have unanimously predicted. The largest space observatory ever built will soon provide its first image. There is no doubt that they will be emotionally accompanied by an intense “wow”.

NASA has announced that the first images and spectroscopic data James Webb Space Telescope Will be released July 12. Surprisingly, its first images are expected to be spectacular. But above all, on their technical, scientific and artistic level, we have to go beyond the most beautiful images of Hubble that have amazed us for more than 30 years.

As the largest, most complex, and most expensive space observatory to be launched into space, James-Webb spent six months preparing before embarking on scientific activities, calibrating and aligning its four instruments in its spatial environment. Mirror. This laborious process resulted in the first images and data available, showing the power of the telescope 6.5 meter mirror Unveiling the infrared universe.

There ” The publication of the first color pictures on the web will give us all a once in a lifetime moment to stop and marvel at a scene mankind has never seen before. Says Eric Smith, web program scientist. And to add this picture Decades of dedication, talent and dreams will be the end result – but they will only begin “In the case of teasing, we can’t do better than that!

An expected “wow”

More seriously, and as NASA noted, it’s “ For five years now, the JWST scientific team has been working and wondering what the first goal of this observatory will be “, Which costs astronomy about 10 10 billion. At this price, Americans, Canadians and Europeans who have funded it expect data that will” revolutionize “infrared sky observation.

If we hope that these first paintings will be of great artistic interest, they too should rejoice Astronomer Highlights the remarkable technical performance of professionals and instruments on the satellite. They should also provide insights into what can be expected for James-Web data users. As soon as the observer is turned on and its instruments are properly calibrated, the James-Web Telescope will observe a list of targets one after the other, pre-selected and ranked in order of priority by an international committee.
