Arp 220 is an ultra-luminous infrared #galaxy (ULIRG) that emits 300 times more light than the #MilkyWay. It also happens to glow brightest in infrared light, Webb's specialty.

The new findings from the James Webb Space Telescope #JWST is all about solving the mysteries of #NGC346, which is one of the most dynamic star-forming regions in nearby #galaxies. However, the new findings by Webb have made NGC346 a bit less mysterious.

New images from NASA’s James Webb Space Telescope (#JWST) reveal for the first time #galaxies with #stellar bars — elongated features of stars stretching from the centers of galaxies into their outer disks — at a time when the #universe was a mere 25% of its present age. The finding of so-called barred galaxies, similar to our #MilkyWay, this early in the universe will require #astrophysicists to refine their #theories of galaxy #evolution.

The James Webb Space Telescope #JWST has captured a pair of #galaxies distorting each other as they merge in a great galactic get-together.
The ongoing cosmic collision imaged by Webb is known as II ZW 96. It is roughly 500 million light-years from #Earth and located in the #constellation #Delphinus, according to a Nov. 30 #NASA statement.

One of the new high-resolution simulations of the dark matter enveloping the Milky Way and its neighbor, the Andromeda galaxy. The new study shows that earlier, failed attempts to find counterparts of the plane of satellites that surrounds the Milky Way in dark matter simulations was due to a lack of resolution.
