US President Joe Biden released the first image of NASA’s James Webb Telescope at the White House, Washington in a preview event. This is the first image produced by NASA’s Webb that is the deepest and sharpest infrared image which uncovered the distant galaxies formed billions of years ago.
NASA’s Webb Produced Image Is Called “Webb’s First Deep Field”
Webb’s First Deep Field image features the finest details of Galaxy Cluster SMACS 0723 as it looked like 4.6 billion years ago. It shows thousands of galaxies with such detailed info that unobservable has become observable. NASA’s Webb has helped to mark the ‘faintest objects’ ever visible in the infrared. This observable part in the image is just “this slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground,” says the NASA website.
NASA’s Webb has captured this image, with its Near-Infrared Camera (NIRCam), which is a combination of several frames taken at different wavelengths. It has taken a total of 12.5 hours to capture this much depth of the Universe as compared to Hubble Space Telescope’s deepest fields which would have taken weeks.
Galaxy Cluster SMACS 0723
With Webb’s first deep field image, we are able to observe the slice of the universe, which is the size of a grain of sand, as it appeared 4.6 billion years ago. NASA was able to look at the distant galaxies formed billions of years ago. The most distant galaxies which were not even faintly observable are in the range now because of the image caught by Webb’s NIRCam including the cluster of stars. Now NASA will begin the research to learn more about these distant galaxies, including their masses, age, history, and compositions.
Meanwhile, NASA’s official site reads, “The full suite will be released Tuesday, July 12, beginning at 10:30 a.m. EDT, during a live NASA TV broadcast.”
James Webb Space Telescope
“The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency), “ says NASA’s website
