Three graphs showing plots of various properties of stars in the SMACS 0723 field. Map showing the location of Webb's first deep field, SMACS 0723, and the Magallenic clouds and Magallenic stream. Summers, J., etal. (astro-ph/2306.13037): SMACS0723 star counts show excess near LMC/SMC compared to NEP; 71 stars (ABX27) with D_spectype~240-100 kpc about 10° from LMC; Part of Leading Arm between LMC and MW: 10 mag fainter than Gaia!

Neat results from Rogier Windhorst from JWST PEARLS.
A type Ia supernova at a redshift of z=1.783 (about 3.7 billion years ago) showed up as multiple images in a galaxy warped by gravitational lensing.
Webb's first deep field, SMACS 0723, is rather close to the Magellanic clouds, so there are more stars in the foreground from the Magellanic stream than an area of the sky 180 degrees away.
