NASA's James Webb telescope captures groundbreaking images of distant galaxies - The universe's splendor and breadth are on display like never before, thanks to a new batch of images that NASA released from the James Webb Space Telescope. The images from the new telescope are "really gorgeous," said NASA's Jane Rigby, the operations project scientist for the James Webb Space Telescope. "That's something that has been true for every image we've gotten with Webb," she added. "We can't take blank sky [images]. Everywhere we look, there's galaxies everywhere."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 (five galaxies in the constellation Pegasus); and the galaxy cluster SMACS 0723.

A nursery for the stars-

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.

The image captures part of a "stellar nursery called NGC 3324 at the northwest corner of the Carina Nebula," NASA said. It's roughly 7,600 light-years from Earth."The blistering, ultraviolet radiation from the young stars is sculpting the nebula's wall by slowly eroding it away," the agency added. "Dramatic pillars tower above the glowing wall of gas, resisting this radiation. The 'steam' that appears to rise from the celestial 'mountains' is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation."

Galaxies from 'It's a Wonderful Life' stun scientists

The tight galaxy group called Stephan's Quintet is a "laboratory" for scientists to study the powerful effects galaxies can exert on each other, thanks to new data from the Webb telescope.

"This enormous mosaic is Webb's largest image to date, covering about one-fifth of the Moon's diameter," NASA said. "It contains over 150 million pixels and is constructed from almost 1,000 separate image files."Catch a dying starWebb pulled the veil back on the second star in the Southern Ring Nebula, using mid-infrared wavelengths to capture it in extraordinary detail. "The star closely orbits its companion as it periodically ejects layers of gas and dust," NASA said. "Together, the swirling duo have created a fantastic landscape of asymmetrical shells."

The new image shows the nebula from a nearly head-on view. But if we could see it from its edge, NASA says, "its three-dimensional shape would more clearly look like two bowls placed together at the bottom, opening away from one another with a large hole at the center."
