The James Webb Space Telescope, a new pioneer in space observation, will be launched on December 18 from Kourou, Guyana. After a 29-day journey, you will arrive at the Lagrange point L2, in the direction opposite the sun. Thanks to its larger mirror than the Hubble mirror, 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 days to wait. On July 12, a NASAI’ESA and theCSA The Canadian Space Agency will release the first images from the James Webb Space Observatory as well as the first spectroscopic data.

One of the images that will be revealed is the deepest image of our universe ever obtained, NASA Administrator Bill Nelson said at a press conference yesterday. ” It’s farther than humanity has ever seen “Declare and qualify telescope From ” Nothing less than a real scientific achievement Thus this image will exceed that of the ultra-deep field ofHubblewho became creative. At the moment, it is not known whether James Webb observed the same point that Hubble observed from theSouthern Hemispherelocated in constellation the oven.

Pictures to change the vision of astronomy

So the photos were chosen to be published. They were chosen for scientific considerations, their ability to demonstrate the scope of the telescope’s capabilities, but also for their artistic interest and anticipated colorful beauty, NASA said. will reveal each image. Different aspects of the universe Infrared Unprecedented detail and sensitivity James Webb scientists said.

In addition to the deepest infrared view of Universe So now, the photos will also show how a file galaxies interact and evolve. It may also appear stars Dying plants are populating the galaxy with new elements and dust that may one day become part of new planetary systems. Will James Webb revisit the Eagle Nebula (M 16) and the iconic Pillars of Creation? We suspect NASA didn’t.” annoying “ All pictures to be posted…

Regarding the spectral data, among the spectra Acquired, the number from whichatmosphere from one extrasolar planet Which can help us determine which molecules What is present in its atmosphere and whether the observed exoplanet can be habitable, not to be confused with “being inhabited”.

At the conclusion of this press conference, everyone was convinced that James Webb should revolutionize astronomy and answer many questions such as ” Where did we come from? “,” who are we ? ” And the ” What’s more? »

Other good news: We knew it, thanks Ariadne 5James Webb It will work longer than expected, 10 years versus 5 years initially planned. In the end, careful calculations showed that there was enough fuel to run it for at least 20 years.

Save the date! The first ‘real’ photos of James Webb will be revealed soon

Article from Remy Decor Posted on 05/06/2022

Humanity is about to marvel at the next scene presented by the James Webb Telescope, and that’s basically what astronomers unanimously expect. The largest space observatory ever built will provide its first images soon. No doubt they will accompany a very emotional “Wow”.

NASA has announced that the first images and spectroscopic data from the James Webb Space Telescope will be announced on July 12. Unsurprisingly, her first photos are expected to be stunning. But above all, they will have to transcend, on a technical, scientific and technical level, the most beautiful Hubble images that have fascinated us for more than 30 years.

As the largest, most complex and expensive space observatory ever launched into space, James Webb went through a six-month preparation period before beginning scientific operations, calibrating his four instruments in his spatial environment and aligning their mirrors. This painstaking process resulted in the appearance of the first images and data, demonstrating the power and strength of the telescope 6.5m diameter mirror Unveiled the infrared universe.

there ” Publish the first pictures in the color Webb will save a once in a lifetime moment for all of us to stop and marvel at a sight humanity has never seen before. said Eric Smith, a web software scientist. To add these photos It will be the culmination of decades of dedication, talent and dreams – but it will also only be the beginning In terms of harassment, we couldn’t do better than that!

expected “wonderful”

The most serious, and as indicated by NASA, this “ For five years now, the JWST science team has been working and thinking about the first goals of this observatory “which has an astronomical cost of about $10 billion. At that price, the American, Canadian and European citizens who funded it expect data that will “revolution” in infrared sky observation.

If we expect these first images to be of great artistic interest, they should also be delightful Astronomy scientists Specialists highlight the phenomenal technological performance of the devices on board the satellite. They should also provide insight into what to expect users of James-Webb data. Once the observatory is up and running and its instruments are properly calibrated, the James Webb telescope will, one by one, monitor a list of targets previously selected and prioritized by an international panel.
