Thin Disks of Galaxies Already Existed in the Young Universe ⚡ экспресс
Original: "Early thin-disc assembly revealed by JWST edge-on galaxies"
Pictures from the James Webb telescope showed that flat, pancake-like stellar disks appeared way earlier than we thought.

Pancake galaxies in the early Universe. The Webb telescope showed that thin stellar disks existed already 11 billion years ago. Previously, it was thought they thickened over time, but now it's the opposite: elegant 'pancakes' appeared first, and the puffy thick disks grew later. This changes the picture of how galaxies grow up.
🎯 If you shrunk the disk of our Milky Way to the size of a vinyl record, its thickness would be comparable to a sheet of paper.
