hierarchical_section_title: Gioiello (galaxy cluster)
caption_attribution_description: English: The most massive cluster of galaxies with an age of 800 million years or younger has been discovered and studied. X-ray data from Chandra allowed astronomers to accurately determine the mass and other properties of this cluster, nicknamed the "Gioiello" (Italian for "Jewel") cluster. This composite image of the Gioiello Cluster contains X-rays from Chandra (purple), infrared data from Herschel (red), and an optical image from Subaru (red, green, and blue). Results like this help astronomers better understand how galaxy clusters, the largest structures in the Universe held together by gravity, have evolved over time.
context_page_description: The Gioiello Galaxy Cluster was discovered using high redshift with NASA's Chandra X-ray Observatory from a research group led by Paolo Tozzi and Joana Santos. Gioiello is the most distant massive galaxy cluster that has been found and studied today. This massive galaxy cluster weighs 400 trillion times the mass of the sun and is located 9.6 billion light years away from Earth. Gioiello, meaning Jewel in Italian, was given to this massive galaxy cluster because an image of the cluster contains many beautiful pink, purple, and red sparkling colors from the hot X-ray emitting gas and other star-forming galaxies within the cluster.
