Giant Telescope Begins Decade-Long Mission to Map the Universe
Table of Contents
A groundbreaking telescope, featuring the world’s most powerful astronomical camera, has commenced a ten-year mission to map the southern sky with unprecedented detail. This aspiring project,involving over 1,000 researchers,promises to revolutionize our understanding of the cosmos and potentially shed light on the enigmatic nature of dark energy.
Sandrine Thomas, the deputy director of construction for the observatory, guided a recent tour, showcasing the telescope’s remarkable components. “The first coating, a thin layer of silver on the mirror surface, was completed at the end of April,” she explained. “This step allows you to improve its reflectivity to better capture the light emanating from distant celestial objects.”
The telescope’s heart, a 3200-megapixel camera, resides in a pristine clean room. This camera, a marvel of engineering, is capable of capturing 800 images of the night sky each night. “The camera will take 800 photos of the celestial vault every night, with a resolution of 3200 Mpx,” a team member noted.
The 3.42-meter secondary mirror was installed in August, adding to the telescope’s remarkable capabilities. Significant contributions came from the French national Institute of Nuclear Physics and particle Physics (IN2P3) of the CNRS. Pierre Antilogus, who coordinated the French collaboration, stated, “The IN2P3 teams notably participated in the manufacturing of the focal plane, made up of 200 CCD photographic sensors.”
The French researchers also provided the camera‘s filter changer, a crucial component that allows for the use of five different color filters, each weighing between 24 and 38 kg. “Thay are necessary to determine the distance from Earth and the age of the objects observed,” Antilogus explained.
Mapping Billions of Stars and Galaxies
The 2.8-ton camera features a unique blade shutter, ensuring uniform pixel illumination, and nitrogen cooling to maintain a sensor temperature of -100°C, minimizing noise and maximizing performance. Over the next ten years, it will capture 800 images nightly, each covering an area forty times the size of the Moon. Dominique Boutigny from the Annecy Particle Physics Laboratory enthusiastically declared, “This is the first time that we have mapped the universe in this way.”
NoirLab estimates the telescope will gather data on 20 million galaxies and 17 billion stars. “We estimate between 15 and 20 terabytes the volume of raw data that will be collected each day,” Boutigny noted, adding that “40% of the data will be processed in France,” primarily at the IN2P3 computing center in lyon.
Unlocking the Mysteries of Dark Energy
The 600-ton dome, equipped with a rail system, assists the telescope’s rotation, with the camera repositioning every 39 seconds to scan the entire expanse of the southern sky. As workers finalize the installation of ventilation shutters to minimize stray light, the anticipation for the scientific breakthroughs this project promises is palpable. The data collected will be instrumental in furthering our understanding of dark energy, a mysterious force driving the accelerated expansion of the universe.
Vera C. Rubin Observatory: poised to Rewrite Our Understanding of the Universe
Nestled high in the Chilean Andes, the Vera C. Rubin Observatory is on the verge of transforming our understanding of the cosmos. This ambitious project, the culmination of decades of work by over 1,000 researchers, is set to unveil unprecedented views of the universe, potentially answering some of the most profound questions in astrophysics.
the observatory’s centerpiece is a 3,200-megapixel camera—the largest digital camera ever built—capable of capturing images of 17 billion stars in a single exposure. “The project was officially launched in the early 2000s,” notes a scientist involved in the project, “It’s a pleasure to see it finally come to fruition.” The main mirror installation was completed on October 14, 2024, with camera installation slated to begin in January 2025.
While full operational capacity is expected in early fall 2025, initial images are anticipated as early as June 2025. “The images will be different from the James Webb telescope,” explains Pierre Antilogus, highlighting a key distinction. ”The latter is designed to observe a particular object, while our camera will scan the entire universe. The impact of these photos will undoubtedly be very strong.”
Beyond the stunning visuals, the data collected by the Vera C. Rubin Observatory has the potential to challenge existing cosmological models. Scientists anticipate a deeper understanding of dark matter and dark energy, which constitute approximately 75% of the universe’s composition. “This is one of the greatest mysteries of physics,” explains Christopher Stubbs, a professor at Harvard University. The observatory’s capabilities extend to identifying potentially hazardous asteroids, analyzing transient celestial events like supernovae, and even searching for evidence of a hypothetical ninth planet, six times the mass of Earth, lurking at the edge of our solar system. “If this planet exists, it will necessarily be spotted by Rubin,” states Dominique Boutigny.
Chile’s selection to host this groundbreaking project underscores its burgeoning role in global astronomy. The country’s exceptionally clear skies and low humidity will make it home to over 50% of the world’s astronomical capacity by 2030. Complementing the Vera C. Rubin Observatory, the Extremely Large Telescope (ELT), a European project, is slated for completion in 2028 in the Atacama Desert. this telescope, boasting a 39.3-meter diameter main mirror, will be the most powerful ever constructed.
“The observation program has not yet been precisely defined, but we will try to minimize frustrations,”
the anticipation within the scientific community is palpable. The Vera C. Rubin Observatory represents a giant leap forward in our quest to understand the universe, promising a wealth of discoveries that will reshape our understanding of the cosmos for years to come.
