Thanks to the James Webb telescope's deep and sharp infrared images, Earthlings are getting a more detailed look at distant galaxies than was ever possible. Check out the latest batch of images released by NASA:

The bright star at the center of NGC 3132, Southern Nebula Ring, while prominent when viewed by NASA’s Webb Telescope in near-infrared light, plays a supporting role in sculpting the surrounding nebula. A second star, barely visible at lower left along one of the bright star’s diffraction spikes, is the nebula’s source. It has ejected at least eight layers of gas and dust over thousands of years.

The images reflect five areas of space that researchers agreed to target: the exoplanet WASP-96 b; the Southern Ring Nebula; the Carina Nebula; Stephan’s Quintet ; and the galaxy cluster SMACS 0723.One of the most eye-popping images released on Tuesday depicts what looks to be cosmic cliffs, valleys and mountains — albeit with mountains that stretch to seven light-years in height.

An enormous mosaic of Stephan’s Quintet is the largest image to date from NASA’s James Webb Space Telescope, covering about one-fifth of the Moon’s diameter. It contains over 150 million pixels and is constructed from almost 1,000 separate image files. The visual grouping of five galaxies was captured by Webb’s Near-Infrared Camera and Mid-Infrared Instrument .

A transmission spectrum made from a single observation using Webb’s Near-Infrared Imager and Slitless Spectrograph reveals atmospheric characteristics of the hot gas giant exoplanet WASP-96 b. But that speck contains multitudes. And thanks to the telescope’s deep and sharp infrared images, Earthlings are getting a more detailed look at distant galaxies than was ever possible.
