Exactly one year has passed since the James Webb Space Telescope commenced its scientific operations. To commemorate this milestone, NASA releases a breathtaking new image that depicts a small star-forming region in the Rho Ophiuchi cloud complex. This image was chosen to symbolize a transformative year of astronomical study, which began with the telescope’s “first light” reveal of the Stephan’s Quintet galaxies, the Carina Nebula, the Southern Ring Nebula, and the exoplanet WASP-96b on July 12, 2022.
NASA Administrator Bill Nelson expresses awe at the telescope’s achievements, stating that every new image showcases a groundbreaking discovery. Webb’s contribution to the field of science empowers researchers worldwide to explore questions that were once unimaginable. Nelson also emphasizes the international collaboration involved in making this scientific feat possible, highlighting the tireless efforts of engineers, scientists, and leaders who dedicated their passion to the mission.
The newly released image is available for download from NASA’s website and can also be obtained in high resolution from the Space Telescope Science Institute’s website.

First Year in Space
The James Webb Space Telescope’s inaugural year in space has been marked by stunning discoveries, including the remarkable “Webb Deep Field” images that offer a glimpse into galaxies and stars closer to the Big Bang than ever observed before. Webb has successfully identified exoplanets and analyzed the atmospheres of numerous alien worlds. Moreover, it has revolutionized our understanding of the solar system, with recent highlights being the captivating infrared image of Saturn and the observation of a plume of water vapor emanating from Saturn’s moon Enceladus.
Among the notable achievements are the groundbreaking infrared images of Jupiter, which unveil the planet’s storms, cloud bands, aurora, rings, and moons.

Secret Weapons
The James Webb Space Telescope’s remarkable discoveries are made possible by its ability to capture far-infrared light, a feature unparalleled in any previous space telescope. This type of light, which is invisible to the human eye, provides insights into ancient celestial objects located at vast distances. Webb’s secret weapon is its Near-Infrared Camera (NIRCam), specially designed to detect infrared light as heat. To detect faint heat signals, the telescope’s instruments are situated on a super-cold side, maintained at approximately -385ºF (-233ºC) by a tennis court-sized sun-shield composed of kapton. The insulation between the shield’s layers further enhances its thermal protection.
Making the Invisible Visible
Webb’s ability to capture infrared light, which is imperceptible to the human eye, is accomplished by mapping the detected light onto the visible spectrum using filters. Another remarkable feature of the telescope is its enormous mirror, unlike any other sent to space. This beryllium-made primary mirror is 6.6 meters in size, enabling it to gather six times the amount of light as the Hubble Space Telescope. Each hexagonal segment of the mirror is coated with an exceptionally thin layer of gold that excels at reflecting infrared light.
Webb’s Place in Space
In contrast to the Hubble Space Telescope, Webb is situated at Lagrange Point 2, which is four times the distance between the Earth and the Moon. This stable point, situated on the opposite side of the sun, is where the gravitational pull of the Earth and the sun cancels each other out. Webb’s exceptional launch accuracy and trajectory have resulted in substantial fuel savings, leading engineers to anticipate an operational lifespan that exceeds the initially planned decade.
