The next great human observatory is gradually sharpening its vision and making good progress in discovering the mysteries of the world. The James Webb Space Telescope, launched in December, reached 1.5 million kilometers from Earth in late January and is now preparing hard to begin. It's a $ 10 billion science mission. Has recorded another in its preparation process.
This Telescope has also met all the optical parameters required by engineers and delivers light clearly to its instrument. "This assurance assures NASA that the observatory has achieved its scientific goals." We have completely focused and focused the Telescope on a star, and its performance shows the desired technical characteristics. We now know that we have built an accurate telescope.
According to a NASA statement, the new image focuses on a star called 2MASS J17554042 + 6551277. This indicates that a new target has been selected for the observatory: the previous stages of the launch process, focusing on the star HD 84406, located 241 light-years away in the constellation Ursa Major.

Stars and other galaxies that the agency has not identified are also visible in the background of the newly recorded image. The James Webb's observational power comes in part from the telescope's massive 6.5-meter-diameter mirror. But it was not possible to throw a mirror of this size directly, so the observatory's designers divided the golden surface into 18 separate adjustable hexagons.
For weeks, mission engineers were fine-tuning and aligning this. There were sections to focus the world on this huge observatory. NASA stressed that the alignment process is not yet complete, but the most difficult and disturbing steps are now over.
Thomas Zurbuchen, NASA Deputy Director of Science Mission, said: , The web team began building the most powerful Telescope ever placed in space, and came up with a bold optical design to meet scientific goals. "Today we can say that this design will work."
NASA also released a selfie using a lens designed to capture the original mirror to help engineers align. According to NASA, once the mirror alignment is complete, perhaps by early May, another important preliminary step for the team will be to calibrate the instruments on the observatory. The work is expected to be completed by summer, after which James Webb will be able to begin his scientific observations. , Evaluates habitable planets on extrasolar planets and identifies the effect of mysterious dark matter on the universe. /> Credit: NASA/STScI
