James Webb combines 18 stars into one [우주로 간다]

Cnet reports that the James Webb Space Telescope (JWST), the largest and most powerful space telescope in human history, which recently sent the first space images and selfies to Earth, recently finished modifying 18 mirror pieces and improving clarity. Recently.

The James Webb Space Telescope gets the best image of space by coordinating 18 gold-plated hexagonal mirrors designed to work together to act as a single mirror.

On the 11th (local time), NASA released the image “HD-84406”, one of the stars that make up the constellation Ursa Major, an image of a single star reflected in 18 mirrors before the mirror is adjusted.

Next, NASA went through a segment alignment step that precisely tuned 18 individual mirrors. The research team tweeted a GIF of the telescope before and after the partial alignment. In this image you can see how the telescope focuses more clearly.

Then, after the images were successively combined to increase sharpness and reduce noise, NASA captured and released the images.

NASA will continue to adjust the mirrors “to make the point of starlight more and more sharp and focused in the coming weeks.” The full mirror alignment process for the James Webb Space Telescope is expected to begin in early February and last for three months.

The James Webb Space Telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency. Scientists hope that James Webb will be able to find a habitable planet in space.
