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

Another 12 days to wait. On July 12th NasaI’ESA andCSA (Canadian Space Agency) will release the first images from the James-Webb Space Observatory as well as the first spectroscopic data.

NASA chief Bill Nelson told a news conference yesterday that one of the images to be revealed is the deepest image of our universe that has ever been acquired. ” It’s longer than humanity has ever seen before “He declared and qualified it telescope of ” nothing less than a true scientific achievement “. This image will therefore surpass the ultra-deep field ofHubble, which has become iconic. At present, it is not known whether James-Webb observed the same point as Hubble from the regionsouthern hemispherelocated in constellation of the Oven.

Images to change the vision of astronomy

The images that are published are therefore selected. Nasa said they were selected based on scientific considerations, their ability to demonstrate the scope of the telescope’s possibilities and also for their artistic interest and expected colorful beauty. Each of the images will reveal ” different aspects of the universe infrared in unprecedented detail and sensitivity said the James-Webb scientists.

In addition to the deepest infrared views cosmos to date, the pictures will also show how galaxies interact and evolve. They can also show stars dying plants that sow the galaxy with new elements and dust that may one day become part of new planetary systems. Will James-Webb revisit the famous Eagle Nebula (M 16) and its iconic Colonies of Creation? We assume that NASA has not ” teased “ all the pictures that will be published …

With regard to the spectroscopic data, i.a. spectra acquired, figure, that of theatmosphere of one exoplanet which could help us identify which ones molecules exists in its atmosphere, and whether the observed exoplanet could potentially be habitable, not to be confused with “being inhabited”.

As a conclusion to this press conference, everyone is convinced that James-Webb should really revolutionize astronomy and answer a wide range of questions such as ” where do we come from? »,« Who are we ? “and” what else is there? »

Other good news: we knew it, thanks Ariadne 5James Webb will work longer than expected, 10 years versus 5 years originally planned. Eventually, finer calculations showed that there was enough fuel to run it for at least 20 years.

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

Article by Remy Decourt published on 05/06/2022

Mankind is wondering about the next spectacle offered by the James-Webb Telescope, this is basically what astronomy experts unanimously predict. The largest space observatory ever built will soon deliver its first images. No doubt they will be emotionally accompanied by an intense “Wow”.

NASA announces that the first images and spectroscopic data from the James-Webb Space Telescope will be released on July 12. Not surprisingly, its first images are expected to be spectacular. But above all, they must surpass, on a technical, scientific, and artistic level, the most beautiful images of Hubble that have amazed us for more than 30 years.

As the largest, most complex, and expensive space observatory ever launched in space, James-Webb underwent a six-month preparation period before it could begin scientific operations, calibrating its four instruments in its spatial environment and adjusting its mirrors. This careful process resulted in the first images and data demonstrating the power of the telescope and its 6.5 meter mirror revealed the infrared universe.

the ” publication of the first images in color by Webb will give us all a moment in life where we can stop and marvel at a sight that humanity has never seen before. said Eric Smith, Web program researcher. And to add these pictures will be the culmination of decades of dedication, talent and dreams – but they will also only be the beginning In terms of teasing, we can not do better!

An expected “wow”

More seriously, and as NASA points out, this “ For five years now, JWST’s scientific team has been working and thinking about what will be the first goals of this observatory. “, Whose astronomical cost is about $ 10 billion. At this price, the American, Canadian and European citizens who funded it expect data that will “revolutionize” the observation of the sky in the infrared.

If we expect these first images to be of great artistic interest, they should rejoice as well astronomers professionals and highlight the enormous technological performance of the instruments on board the satellite. They should also provide insight into what they can expect from users of James-Webb data. Once the observatory is operational and its instruments are properly calibrated, the James-Webb Telescope will, one by one, observe a list of targets pre-selected and ranked in order of priority by an international committee.
