First Webb Telescope image reveals oldest galaxies formed since the Big Bang

This first image from NASA’s James Webb Space Telescope is the deepest and sharpest infrared image ever taken of the distant universe.

Known as Webb’s first deep field, this image of the galaxy cluster SMACS 0723 is packed with detail. Thousands of galaxies, including the faintest objects ever seen in the infrared, have appeared in Webb’s view for the first time. This piece of the vast universe covers a piece of sky roughly the size of a grain of sand held at arm’s length by someone on the ground.

This deep-field, taken by Webb’s Near-Infrared Camera (NIRCam), took a total of 12.5 hours to acquire depth at infrared wavelengths beyond the deepest regions of the Hubble Space Telescope, a composite composed of images at different wavelengths, including weeks seem.

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying the more distant galaxies behind it. Webb’s NIRCAM brings those distant galaxies into sharp focus; they have tiny, faint structures never seen before, including star clusters and diffuse features.

Researchers will soon begin learning more about the masses, ages, history and compositions of galaxies, as Webb searches for the oldest galaxies in the universe.

Meanwhile, NASA, in partnership with the European Space Agency (ESA) and the Canadian Space Agency (CSA), will release. James Webb Space Telescope’s first full-color images and spectroscopic data During the live broadcast on Tuesday. The photographs will be released one after the other by the three space agencies.

The Webb telescope lifted off on an Ariane 5 rocket from Europe’s Spaceport in French Guiana on its mission to uncover the mysteries of the universe on December 25, 2021. The spacecraft traveled for over a month to reach its destination about 15,00,000 km from home for an uninterrupted view of the universe.
