James Webb Telescope's Deep Field -- What Would Be Behind A Grain of Sand Held at Arms Length. Click on the Picture


 NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe is approximately the size of a grain of sand held at arm’s length by someone on the ground.

  1. Webb snapped that image in a few hours. Hubble took nearly 2 weeks for it's deep field image. I'm looking forward to some stunning results over Webb's expected service life.
