James Webb sent his first sharp picture, it’s beautiful – Teach me about science
Although the purpose of this image is to focus on the brightest star in the center to evaluate the alignment of the telescope, the optical systems of Webb and NIRCam are very sensitive, with galaxies and stars visible in the background. (Credit: NASA / STScI).

We finally see the long-awaited sharp image captured by the most powerful telescope in history. NASA showed new images from the James Webb Space Telescope a few hours ago Thus ensuring proper alignment and that all optical parameters work as well as they can.

To show what its potential is, the Web focused on a bright star called 2MASS J17554042 + 6551277, also known as TYC 4212-1079-1, located 2,000 light-years away. Click on it Here See image in better resolution.

Webb’s goal in the film is to focus on a bright star, but his optics are very sensitive, visible in the background of galaxies. This film is still part of the telescope product, align the glass. We now know that everything is going well, and JWST is expected to exceed its scientific goals.

“We’re fully aligned with the telescope and focused on one star, and the performance exceeds the specifications. We’re happy with what it means to science.” Ritwa Kesky-Kuha said in a statement, Deputy Manager of the Web Optical Telescope Element at NASA’s Goddard Center. “We now know that we have developed the right telescope.”

We have a new “selfie” that was created from the NIRCam tool using a special bubble imaging lens, which is designed to take pictures of the primary glass segments rather than the sky. (Credit: NASA / STScI).

The James Web Space Telescope, also known as the Web or JWST, is an international project run by NASA in partnership with its partners ESA (European Space Agency) and the Canadian Space Agency. Its development was due to the work of more than a thousand scientists from all over the world, who had to deal with continuous difficulties for more than 2 decades.

The main objectives of this mission are: 1) to search for the first galaxies or glowing objects to form after the Big Bang. 2) Determine how galaxies formed from their formation until now. 3) Observe the formation of the stars from the starting position of the planets. 4) Measure the physical and chemical properties of planetary systems, including our own solar system, and explore the possibility of living in those systems.

The web is designed to absorb infrared light, light that is outside the visible spectrum and beyond what we can see with our human eyes. Longer wavelengths of infrared allow dust to penetrate more easily, allowing you to see more clearly; In addition, it allows scientists to move over time due to an event called the Red Shift. That is, the telescope acts as a powerful time machine that, during its scientific observations, can capture light traveling in space since the first stars and galaxies formed on Earth 13.5 billion years ago. Early universe.

The Web is now the world’s leading space science laboratory, considered the successor to the famous Hubble Space Telescope, but not an alternative because the missions will be filled as long as its instruments continue to operate. The web is a $ 10 billion engineering marvel that will help solve the mysteries of our solar system when it is fully operational, beyond which we can explore distant worlds around other stars and explore the mysterious structures and origins of the solar system. The universe and our place in it.
