NASA’s James Webb Space Telescope (JWST) successfully aligned its mirrors, capturing the first images of a star, providing scientists with a glimpse into the deepest reaches of space.
Bullseye! James Webb Space Telescope Arrives at Final Alignment Milestone
The James Webb Space Telescope (JWST) team released the first images taken by the telescope after it completed the final alignment of its mirrors. The images show a star called 2MASS J17554042+6551277, captured by the Near-Infrared Camera (NIRCam) instrument.
The alignment process began in January 2022, when the telescope was launched into space. The process involved adjusting the position of the telescope’s 18 hexagonal mirror segments to within nanometers of their ideal positions. The fine-tuning was accomplished using a sophisticated system of actuators that precisely moved each mirror segment until the telescope achieved diffraction-limited performance, allowing it to focus light with the precision needed for scientific observations.
“This is a major milestone for the Webb mission, and it brings us one step closer to unlocking the full power of this incredible telescope,” said Thomas Zurbuchen, NASA’s associate administrator for science. “These first images are just a taste of the amazing science that Webb will produce in the years to come.”
The first images from Webb reveal unprecedented detail in the infrared spectrum, capturing the star 2MASS J17554042+6551277 surrounded by diffraction spikes, a pattern created by the telescope’s hexagonal mirror segments.
“We are thrilled with the performance of the telescope,” said Marcia Rieke, principal investigator for NIRCam. “The images are sharp and clear, and they show that Webb is ready to begin its scientific mission.”
The Webb telescope is the most powerful and complex space telescope ever built, and it is expected to revolutionize our understanding of the universe. The telescope’s primary mission is to study the early universe and the formation of galaxies, stars, and planets. Webb will also investigate exoplanets, searching for signs of life beyond Earth.
“The release of these first images is a historic moment for astronomy,” said Knicole Colón, program scientist for the Webb telescope at NASA. “Webb is a game-changer, and we can’t wait to see what scientific discoveries it makes in the years to come.”
