July 11, 20223 yr Popular Post Quote This first image from NASA’s James Webb Space Telescope is 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 covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground. https://www.nasa.gov/webbfirstimages Edited July 11, 20223 yr by sidis
July 11, 20223 yr Author here's a sense of scale on the primary mirror on this beautiful bastard. i used to be proud of my 11 incher...now i feel inadequate. Edited July 11, 20223 yr by sidis
July 11, 20223 yr Author Popular Post imaging of the galactic cluster is from approximately 4.6 billion years ago. slightly older than the age of our lovely home planet and about the time armybrat was born.
July 11, 20223 yr It turns out deep space is still really into disco. With this being an IR telescope, how do they translate that into a visible "color" image? And why do some objects have giant diffraction spikes? I thought that was an optical phenomenon.
July 11, 20223 yr Close your eyes and rub them with your hands for a few seconds and that image will appear. Edited July 11, 20223 yr by Pato del Muerto

This will help study objects out in the outer reaches of the observable universe. Since the space between is expanding faster than the speed of light the observable universe is constantly shrinking for us and we'll never have any way to know what's outside of it.

July 12, 20223 yr So the first thing they did after building this thing for 30 years and flying it 750k miles into space is take the same picture their last camera took, just to see if it was better?

Know how I know you aren’t an amateur photographer who buys a new camera every few years in the belief the latest and greatest will make you a better photographer?
