July 12: First picture on the web

The James Webb Space Telescope (JWST) is the largest space telescope with a 6.5 meter diameter mirror. Initiated by NASA, the program is partnered by the European Space Agency (ESA) and the Canadian Space Agency (CSA). The next two instruments were supplied, but ESA also took care to launch the observatory with the Ariane 5 on December 25, 2021.
After a few months of commissioning and verification of its devices, the web is in order to work This July 12, the images will demonstrate its ability to be declared as unprecedented.

The first picture live on the web

The Tuesday, July 12 date was chosen by the web’s partner organizations to release the first images and scientific information to the general public (we quote NASA). “The most powerful space telescope ever built
The event will be broadcast live and in English on NASA’s YouTube channel in the window below.

This video window will switch to retransmission and become a replay later.
The Directly To get started Tuesday, July 12 at 4:30 p.m., Metropolitan France time. Websites dedicated to telescopes by the Space Telescope Science Institute (STScI), along with partner agencies, will be updated to show images (list below):
NASA website
ESA website
CSA website
STScI website

This event will be relayed in the Cité de l’espace exhibition In Toulouse. For this event, Cité de l’espace moderators will comment on the broadcast images and explain directly to the audience. They will return to the occupied territories of France on cruise, architecture and instruments of the James Webb Space Telescope and on missions to observe the universe. This July 12 will also be the occasion to open the Center for Scientific Culture to the public A new place dedicated to the web and its predecessor Hubble.

Why do we say “first picture”?

No one can question, because Previous images acquired by the web were published, However, these are of a technical nature and are used to test the good health of telescopes. Thus several have described in detail the method of aligning 18 hexagons of 1.3 m which forms the 6.5 m initial mirror of JWST. At the end of March, a Dr. Technical picture The galaxies in the background have shown that the telescope has given the expected performance, or a little more.
Most recently, on July 7, a snapshot taken in mid-May with the Canadian instrument FGS (Fine Guidance Sensor) went further with the galaxy of the galaxy! Look down.

The shot was taken to test the Canadian instrument FGS’s ability to point at a star and track it by moving the telescope finely. Apart from a few stars (easy to spot, they have 6 branches due to hexagonal mirrors), one can only notice an extraordinary abundance of galaxies.

This image compiles 72 images obtained in 32 hours. Scientists working on the web think so One of the deepest images in the universeA. The long pause associated with infrared performance makes it possible to see extremely distant galaxies.
As impressive as this picture is, it is again a technical shot. And that’s why we speak for the “first picture” on July 12 in the sense that they will First using the scientific capabilities of the web’s instruments. It should be noted that press releases from NASA, ESA and CSA announce the first images in the plural. So we can expect multiple shots … it’s also specified “full color”, which means web team Orange seen so far can take advantage of different wavelengths of infrared to present color shots instead of monochromatic ones. In conclusion, let’s keep in mind that these images, which will probably be spectacular, will only scratch the surface that the web could bring to astronomy in the coming years. The scientific community actually hopes for a revolution in our knowledge of the universe that was made possible by Hubble.
