Does someone know why the bright stars in the image do not show the hexagonal pattern that is present in published images of Webb?

- Cthulhu_ 2y agoI presume it's not a live view of what Webb is seeing but existing images / visualisations from other sources pointing in the same direction Webb is right now.
- delecti 2y agoMy understanding is that the 6-pointed spike diffraction pattern only occurs on stars, and that the bright points without them are galaxies.
- privong 2y agoThe background image is not data from Webb; it is a near-infrared image from the 2 Micron All-sky Survey (2MASS). See @skybrian's comment: https://news.ycombinator.com/item?id=40013769 https://news.ycombinator.com/item?id=40013769
