James Webb Takes Space Telescope ‘Selfie’

Launched into space on December 24, 2021 to shed light on the darkest secrets of the universe. James Webb Space TelescopeThe excitement continues to increase with every new news from . The James Webb Space Telescope, which reached the observation point 18 days ago after a month’s journey, detected the first star signal 6 days before that, and made us feel that this is just the beginning.

Following these developments, NASA announced that Webb had a Friday meeting. ‘selfie’ reported that he did. In addition, the telescope your first starIt was also recorded that he saw me.

James Webb Space Telescope selfie captivated Webb team

Although NASA has said that it is not possible for the telescope to take selfies in its previous statements, it seems that the telescope fans to pamper It looks like he’s decided. Noting that the Webb team was not sure before whether it was possible to obtain such an image using only starlight, Webb optical telescope element manager Lee Feinberg said in a statement that their reaction to Webb’s selfie was taken. “Oh my God” means it is.

“Even when we tested it in Houston, we didn’t have the starlight illuminating the main mirror in this configuration.” Feinberg said that this is something new for the team as well, and that the team is almost in the face of development. you’re fascinated he adds to his words.

Webb also took a photo of his first star

In addition to all this, Webb also obtained his first star images. The statement said all these steps involved months of aligning the telescope’s huge golden mirror, which is believed to begin unraveling the mysteries of the universe’s history by this summer. part of the process was stated. On the other hand, the first image that Webb sent from the universe to Earth, although not very impressive in the image, is for humanity. their promise for the future quite in terms of stunning.

In the image of 18 blurry white dots on a black background, each dot actually shows the same thing: a bright, isolated star in the constellation Ursa Major. HD84406. This photo actually represents a very important milestone for us. The image, with 18 dots captured by the 18 individual pieces of the primary mirror, now gives scientists a way to align and focus these hexagonal pieces. basis forming.

Going back 13.5 billion years to study the first galaxies

The light detected by Webb passes through the segments and reflects on its secondary mirror, a round object at the tip of the telescope, and then on the main imaging device, the Near Infrared Camera (NIRCam). This is the first step in taking images and aligning the telescope, said University of Arizona astronomy professor Marcia Rieke, principal investigator of the NIRCam instrument. good progress The entire Webb team was almost happy in front of him.passed out means it is.

The point reached in the image capture process, which began on February 2, with Webb pointing out different positions around the predicted position of the star, also shows that the telescope is already relatively well positioned for final alignment. The selfie we mentioned above is also part of this process. help is stated to have been withdrawn.

In order to reach the first generation galaxies formed after the Big Bang, Webb’s 13.5 billion years His main mission, which involves using his high-resolution tools to go back in time, will begin next summer. In addition, Webb; in order to determine their origin, evolution and habitability. outer planets It will also study distant planets known as
