Editor’s note Looking at the ‘wide world’. We look at ‘humanity’s efforts’ to expand awareness and ground through technological advancement. The story of the vast universe beyond the earth, ‘Cosmo Story’ begins. An image of the Carina Nebula Open Cluster from James Webb’s first full-color image. NASA, ESA, CSA, and STScI. Image processing: J. DePasquale (STScI). The James Webb Space Telescope (JWST), which flew into space on an Ariane 5 rocket from the French Guiana Space Center in December 2021. After regarding half a year of preparation On July 12 last year, we confirmed the historic first results of James Webb. “Our goal is to capture the first images and data from James Webb,” said Klaus Pontofidan, James Webb Project scientist at the Space Telescope Science Initiative (STScI). is to showcase the powerful performance of the telescope and preview the upcoming scientific mission,” he said. “This result will give astronomers and the public the ‘WOW’ they’ve been waiting for.” James Webb’s results made everyone exclaim, ‘Wow!’ and astronomers mightn’t keep their mouths shut at the wonders of the universe observed in infrared light. A year has passed since that impression. On July 12 (local time), the National Aeronautics and Space Administration (NASA) observed a special celestial object and released the results to mark the first anniversary of the release of full-color images of James Webb. This observation target is the ‘Rho Ophiuchi cloud complex’, which is the ‘cradle of stars’ where stars such as the sun are born, and is the closest to a star forming region. It is located regarding 390 light-years from Earth in the southern direction of Ophiuchus. The close proximity of the object and James Webb made it possible to get a detailed close-up of the star. Why did NASA, ESA, CSA, STScI, and Klaus Pontoppidan (STScI) choose this celestial object as the 1st anniversary image? This is presumed to be because it is an object that contains many of the directionality of scientific observations that James Webb aims for. This object appears red as stars are born, intersect with exploding jets, affect the surrounding interstellar gas, and react with nearby hydrogen molecules. . Most of the 50 or so young stars seen in the image are similar in mass to or smaller than the Sun. Only the star ‘S1’, which shines brightly among the bright curtains, is more massive than the sun. Examining the image, infrared observations reveal details of the interior covered by light and dust and changes that cannot be seen with visible light. It also shows the birth and growth of stars and, like our solar system, changes in the composition and formation of matter in stellar disks. Also, red vertical columnar structures made of gas and dust are newly discovered by James Webb’s observations. The location of the ‘Rho Ophiuchi’ cloud complex observed by James Webb. NASA, ESA, CSA, STScI, Klaus Pontoppidan (STScI)The Sun also went through a phase of growing jets like the stars in that image a long time ago. By observing this object in infrared light, we can see how the sun grew and how it formed the stellar system. “In just one year, James Webb might look through a cloud of dust and see the light coming from the edge of the universe,” said NASA administrator Bill Nelson. “The new discovery has enabled scientists around the world to ask and answer questions they never dreamed of.” James Webb’s ‘Precise Spectroscopy’ fascinated scientists. The first full-color deep field image of James Webb released by US President Joe Biden on July 12 last year. The observation target is the SMACS 0723 galaxy cluster. NASA, ESA, CSA, and STScSince US President Joe Biden released the first deep-field image, we are experiencing an astonishing new look at the universe, just like LASIK surgery. Infrared observations are surprising enough, but what excites scientists is their precise spectral capabilities. The ability of James Webb’s near-infrared spectrometer (NIRSpec) has been applied in a variety of ways. First of all, by analyzing the light of the most distant galaxies and very minute changes in redshifted light, the distance to ancient galaxies, the shape of the universe, and the early days of the universe were analyzed. Supermassive black hole discovered. Transit graph of exoplanet WASP-96b. Provided by NASA, it was also possible to analyze the atmosphere of exoplanets such as WASP-39b through transit (observation of changes in the light of a star passing through the atmosphere of a planet). As light passes through the atmosphere of an exoplanet, it is possible to determine whether an exoplanet has an atmosphere and, if so, whether it is a Jupiter-type or terrestrial planet through changes caused by the components absorbing light. It can detect and determine atmospheric components, such as organic carbon molecules. If there is life on the planet, you may find the desired extraterrestrial life through atmospheric analysis. TRAPPIST-1 Red Dwarf System Orbit Explanation Data. Courtesy of National Aeronautics and Space AdministrationJames Webb is currently observing the Trappist-1 red dwarf system, which has been predicted to have life. Here, seven terrestrial planets (b to h) orbit around a red dwarf star smaller than the sun, closer than the orbit of Mercury. It seems to be too close, but thanks to the fact that the red dwarf is smaller than the sun and has a lower temperature, the Goldilocks zone in which life can exist is formed, and four planets (d, e, f, g) orbit here. STScI is observing the TRAPPIST-1 planet sequentially. Image explaining the surface temperature of TRAPPIST-1b. NASA, ESA, CSA, J. Olmsted (STScI); Science: Thomas Greene (NASA Ames), Taylor Bell (BAERI), Elsa Ducrot (CEA), Pierre-Olivier Lagage (CEA)James Webb light curve observing Trappist-1c. NASA, ESA, CSA, Joseph Olmsted (STScI)First of all, the observation results of b and c were released. Atmospheres have not been confirmed on either planet. It’s too close to a red dwarf star for life to exist and receives too much energy, making the surface hot and difficult to create a sufficient atmosphere. Therefore, scientists are focusing their attention on the next object ‘TRAPPIST-1d’ observation. Comparison of images of Uranus and Neptune by James Webb and the Hubble Space Telescope. Courtesy of STScI We’ve discovered many things in observations of our solar system that aren’t far out in space. Clearly captured faint rings of Uranus and Neptune and observed auroras on Jupiter. Imaginary image of doughnut-shaped plumes of water ejected by Enceladus orbiting Saturn. NASA, ESA, CSA, STScI, Leah Hustak (STScI) It was also confirmed that the water ejected from the icy crust of Saturn’s moon Enceladus, observed by the Cassini probe, is distributed in the shape of a giant doughnut in Saturn’s orbit. James Webb compares the components of various molecules and water found in our solar system with those observed in other stellar systems to help efforts to find clues regarding why Earth became the cradle of life and the origins of life on Earth. Facebook capture of NASA’s James Webb Space Telescope NASA Goddard Space Flight Center Webb chief project scientist Jane Rigby said, “With one year of observations, we know for sure how powerful James Webb is, and in the past year we have made some amazing discoveries and data. “he said. James Webb is currently planning to complete Cycle 1 of the first observation schedule on September 30, and start a new observation schedule (Cycle 2) in October. Perhaps thanks to the amazing performance of infrared rays, NASA is said to have recommended a proposal for a ‘much more adventurous task’ to the exploration proposal of Cycle 2. These are the reasons why further exploration is expected. ※ CBS No Cut News changes the world together with your reports.
