The Webb telescope’s mirrors were made in Alabama and assembled and tested for cold resistance at NASA’s Marshall Space Flight Center in Huntsville.
NASA's Hubble Space Telescope made the Pillars of Creation famous with its first image in 1995, but revisited the scene in 2014 to reveal a sharper, wider view in visible light, shown above at left. A new, near-infrared-light view from NASA’s James Webb Space Telescope, at right, helps us peer through more of the dust in this star-forming region. The thick, dusty brown pillars are no longer as opaque and many more red stars that are still forming come into view.
First photographed by NASA’s Hubble Space Telescope in 1995, the pillars are seen much more clearly in the new Webb image. The new images also allow a better count of newly formed stars and the amounts of gas and dust. Here are some things to look and thinks about for in the new image: 1. The “scene stealers,” as NASA calls them, are the bright red orbs, often with “spikes” that lie outside one of the pillars. These orbs eventually collapse under their own gravity becoming new stars.
2. The “wavy lines that look like lava at the edges of some pillars” are ejections from the still-forming stars. Young stars can shoot jets of dust and gas that can collide with the pillars creating bow-shaped waves similar to those a boat makes while moving through the water. The red glow comes from “energetic” hydrogen.4. We are not seeing “through” the clouds at vast distances of space or new galaxies.

Webb Image Release- Webb Space Telescope GSFC/NASAThe Latest NASA Released Webb Image is featured on this page. The James Webb Space Telescope's revolutionary technology will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Webb’s infrared telescope will explore a wide range of science questions to help us understand the origins of the universe and our place in it. Seeking Light from the First Galaxies in the Universe Webb will directly observe a part of space and time never seen before. Webb will gaze into the epoch when the very first stars and galaxies formed, over 13.5 billion years ago. Ultraviolet and visible light emitted by the very first luminous objects has been stretched or 'redshifted' by the universe's continual expansion and arrives today as infrared light. Webb is designed to “see” this infrared light with unprecedented resolution and sensitivity. Exploring Distant Worlds and the Solar System Webb will also be a powerful tool for studying the nearby universe. Scientists will use Webb to study planets and other bodies in our solar system to determine their origin and evolution and compare them with exoplanets, planets that orbit other stars. Webb will also observe exoplanets located in their stars’ habitable zones, the regions where a planet could harbor liquid water on its surface, and can determine if and where signatures of habitability may be present. Using a technique called transmission spectroscopy, the observatory will examine starlight filtered through planetary atmospheres to learn about their chemical compositions.
