[EN VIDÉO] Understand the James Webb Space Telescope mission in a minute
The James Webb Space Telescope, a new flagship in space observation, will launch on December 18 from Kourou, Guyana. After a 29 -day journey, it will reach Lagrange point L2, in the opposite direction of the Sun. With its mirror larger than Hubble, of 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.

Another 12 day wait. On July 12, the inthe ESA and theCSA (Canadian Space Agency) will release the first images from the James-Webb Space Observatory as well as the first spectroscopic data.

NASA boss Bill Nelson stressed at a press conference yesterday that one of the images to be revealed is the deep image of our universe which has never been obtained. ” It is more than what people have seen before “He declared and qualified the telescope in ” nothing less than a real scientific achievement “. So this picture surpasses that of the ultra-deep field ofHubble, which became iconic. At present, it is not known whether James-Webb observed the same Hubble point from the region ofsouthern hemispherelocated at constellation in the Oven.

Images to change the astronomical perspective

So the photos were chosen to be made public. Nasa said they were selected on scientific considerations, their ability to demonstrate the scope of the telescope’s capabilities and also for their artistic interest and expected colorful beauty. Each of the images will reveal ” different aspects of the universe infrared before the occurrence of detail and sensitivity said James-Webb scientists.

In addition to the deepest infrared vision of cosmos to date, the images will also show how galaxies interact and thrive. They can also show up star deadly plants scattering the galaxy with new elements and dust that in the future will be part of new planetary systems. Will James-Webb revisit the famous Eagle Nebula (M 16) and its iconic Pillars of Creation? We suspect NASA did not ” gibiaybiay » all images to be made public …

Regarding spectroscopic data, among the spectra obtained, there is that ofatmosphere on an exoplanet that can help us identify what molecules is in its atmosphere and if the observed exoplanet can be inhabited, it is not to be confused with “inhabited”.

At the end of this press conference, everyone was convinced that James-Webb really needed to change astronomy and answer many questions such as “ where are we from »,« who are you “ug” what else is there? »

Other good news: we know that, thanks to Ariane 5, James-Webb will work longer than expected, 10 years versus 5 years previously planned. Eventually, better calculations showed that there was enough fuel to run it for at least 20 years.

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

People will almost be amazed at the next scene offered by the James-Webb telescope, this is what astronomers predicted. The largest space observatory ever built will provide its first images soon. There is no doubt that they are emotionally accompanied by an intense “Wow”.

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

As the largest, most complex and expensive space observatory since launched into space, James-Webb went through a six-month period of preparation before it could begin scientific operations, calibrating four instruments. it in its spatial environment and aligns with his mirrors. This meticulous process resulted in the first images and data, showing the power of the telescope and its 6.5 meter mirror revealed the infrared universe.

there ” publication of the first pictures of color of Webb will provide a once-in-a-lifetime opportunity for all of us to stop and marvel at a scene that mankind has never seen before. said Eric Smith, Webb program scientist. And to add these images is the culmination of decades of dedication, talent and dreams – but they are also the beginning “. In terms of ridicule, we couldn’t have been better!

Expected “wow”

More seriously, and as NASA points out, it “ For five years now, the JWST scientific team has been working and figuring out what would be the first target of this observatory. “, whose astronomical costs are about 10 billion dollars. At this price, the citizens of America, Canada and Europe who spend it expect the data to” change “the observation of the sky in infrared.

If we expect these early images to have a lot of interest in art, they should also be happy. astronomers professionals and promote the unique technological performance of satellite -based instruments. They should also provide an understanding of what to expect for James-Webb data users. Once the observatory is operational and its instruments have been properly calibrated, the James-Webb telescope will observe, one by one, a list of targets already selected and ranked in order of priority of an international committee.
