HN Theater has aggregated all Hacker News stories and comments that mention V101 Science's video "Thousands of Never Seen Before Galaxies! The Latest James Webb Space Telescope Image Explained in 4K".
Youtube Summary
The James Webb Space Telescope (Webb) has recently captured its first colour scientific image! NASA’s James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe so far. Webb’s First Deep Field is galaxy cluster SMACS 0723, and it is teeming with thousands of galaxies, including the faintest objects ever observed in the infrared. This is the highest resolution infrared image ever taken from space. Webb is the next great space science observatory following Hubble, designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy. Webb will see farther into our origins: from the formation of stars and planets to the birth of the first galaxies in the early Universe.

Hacker News Stories and Comments

All the comments and stories posted to Hacker News that reference this video.
The TLDR is that Webb can see much further across the universe (and thus much further back in time) and at higher higher resolution than Hubble, and Webb’s primarily Infrared sensors can see through nebulae, space dust and other obstructions better. There are numerous videos on the differences, but here are some I found pretty good:

1. Scientific American comparing how far back in time Webb can see vs Hubble: https://youtu.be/nBDHqquK_8k&t=2m8s

2. NASA scientist reviewing Webb’s Carina Nebula image, explaining what Webb is unveiling for the first time, and comparing to the same image from Hubble: https://youtu.be/3y6iWi95ypc&t=2m17s

3. Good overview of Webb and its differences from Hubble: https://youtu.be/JzDWpvtDJ9g
