Galaxies similar to our own Milky Way sprouted up earlier than scientists expected.
JWST seems to show objects that are causing some viewers, headaches :) I note from the paper published for this report.
ref - First Look at z > 1 Bars in the Rest-Frame Near-Infrared with JWST Early CEERS Imaging, https://arxiv.org/abs/2210.08658, 12-Dec-2022. "Stellar bars are key drivers of secular evolution in galaxies and can be effectively studied using rest-frame near-infrared images, which trace the underlying stellar mass and are less impacted by dust and star formation than rest-frame UV or optical images. We leverage the power of JWST CEERS NIRCam images to present the first quantitative identification and characterization of stellar bars at z>1 based on rest-frame NIR F444W images of high resolution .
My observation. The March issue of Sky & Telescope has a report on spiral galaxies."14 Where Do Spirals Come From? Spiral galaxies are ubiquitous in the nearby universe, yet we still don’t know how their patterns arise.""By Monica Young" It seems the need for recycling spiral arms over billions of years is acute and density waves must recreate spiral arms regularly, but they will look different too at different ages.
