Webb's First Deep Field: The first full-color image from NASA's James Webb Space Telescope was released on July 12, 2022 by US President Joe Biden.
- The James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe which contains light from galaxies that has taken many billions of years to reach us.
- The first image of James Webb Telescope, known as Webb's First Deep Field is galaxy cluster SMACS 0723.
- It is teeming with thousands of galaxies – including the faintest objects ever observed in the infrared.
- Among the other Webb subjects were two enormous clouds of gas and dust blasted into space by stellar explosions to form incubators for new stars — the Carina Nebula and the Southern Ring Nebula, each thousands of light years away from Earth.
- The images, created to look more clearly and farther than ever before at the creation of the cosmos, were hailed by NASA as a turning point in cosmic investigation.
- It provides glimpses of what the early Universe looked like.
About the First Image:
- The James Webb Image is one of the telescope’s first-full color images.
- The first photo has been taken by Webb’s Near-Infrared Camera (NIRCam), which has brought distant galaxies into sharp focus.
- It is a composite made from images at different wavelengths, totaling 12.5 hours.
- It covers a patch of sky that is approximately the size of a grain of sand held at arm’s length by someone on the ground.
- The first photographs from the James Webb Space Telescope reach depths at infrared wavelengths beyond the deepest regions that took the Hubble Space Telescope weeks to complete.
- The first image shows galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago.
- The galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it.
- The distant galaxies have tiny, faint structures that have never been seen before, including star clusters and diffuse features.
About James Webb Telescope:
- NASA's James Webb Telescope is the world's largest and most power space telescope ever launched.
- It has been developed by NASA in partnership with ESA (European Space Agency) and CSA (Canadian Space Agency).
- It was launched on December 25, 2021 beginning a one-million-mile journey to see 13.5 billion years into the past.
