![]() ![]() This enormous mosaic is Webb’s largest image to date, covering about. Infrared is just outside the visible spectrum of what humans can see. Today, NASA’s James Webb Space Telescope reveals Stephan’s Quintet, a visual grouping of five galaxies, in a new light. The less than two ounces of 24-carat gold reflect infrared light better than other metals. See snapshots from the earliest days of a next-generation space observatory. The coating is so thin that a single strand of human hair is 1,000 times thicker. The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency). Gallery: James Webb Space Telescopes 1st photos. It's only a golf ball's worth of gold, but still - the James Webb Space Telescope's 18 primary mirror segments are covered in gold. Webb’s enormous size and frigid operating temperature present extraordinary engineering challenges. Webb is NASAs largest and most powerful space science telescope ever constructed. The sunshield gives Webb the equivalent sun protection factor, or SPF, of one million, NASA says. The latest news on NASAs Webb Space Telescope. ![]() The side facing the sun will experience temperatures of about 260 degrees Fahrenheit, while the other side will be chilled to some 370 degrees below zero - a nearly 600-degree difference. Without the shield, the immense heat from the sun would overwhelm the telescope's sensors. ( 1972 ) Cosmic ray isotope and charge resolution using large area Scintillation - Chevernkov total energy telescope, Nucl. This mechanism was folded up when Webb launched on Christmas Day, but less than two weeks later, the extremely thin layers of the shield were successfully deployed. The bright star at the center of NGC 3132, Southern Nebula Ring, while prominent when viewed by NASAs Webb Telescope in near-infrared light, plays a supporting role in sculpting the surrounding. It does that thanks to a five-layer sunshield the size of a tennis court. In order to function properly, Webb needs to be kept cool. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb stays cool with a sunshield the size of a tennis court The James Webb Space Telescope is the world's premier space science observatory. The observatorys image of the Southern Ring Nebula shows rings of gas and dust. Pre-flight testing shows how a final mirror "wing," holding three hexagonal segments, rotates into place to fill out the James Webb Space Telescope's primary mirror. The Webb telescope also spied the last 'performance' of a dying star located more than 2,000 light-years away. If all goes well, Webb will capture light that's been traversing the cosmos for as long as 13.5 billion years, extending our views of the universe several hundred million years earlier than Hubble - back to a time when the very first galaxies were born. ![]()
