NASA releases next wave of images from James Webb Space Telescope

The James Webb Space Telescope began releasing a new wave of cosmic images on Tuesday, heralding a new era of astronomy.
"Every image is a new discovery," said NASA administrator Bill Nelson. "Each will give humanity a view of the universe that we've never seen before."
One new image on Tuesday shown water vapor in the atmosphere of a faraway gas planet. The spectroscopy -- an analysis of light that reveals detailed information -- was of planet WASP-96 b, which was discovered in 2014.
"We've seen the effect of what happens when a planet and its atmosphere passes in front of the star, and the star light filters through the atmosphere, and you can break that down into wavelengths of light," said NASA's Knicole Colon.
Other targets that will be released include Carina Nebula, a stellar nursery, famous for its towering pillars that include "Mystic Mountain," a three-light-year-tall cosmic pinnacle captured in an iconic image by Hubble.
Known as Webb's First Deep Field, it shows the galaxy cluster SMACS 0723, which acts as a gravitational lens, bending light from more distant galaxies behind it towards the observatory, in a cosmic magnification effect.
Here, it remains in a fixed position relative to the Earth and Sun, with minimal fuel required for course corrections.
Webb's primary mirror is over 21 feet (6.5 meters) wide and is made up of 18 gold-coated mirror segments. Like a camera held in one's hand, the structure must remain as stable as possible to achieve the best shots.
Thanks to an efficient launch, NASA estimates Webb has enough propellant for a 20-year life, as it works in concert with the Hubble and Spitzer space telescopes to answer fundamental questions about the cosmos.
