Anthropic said in an Oct. 8 post that Claude Science helped Johns Hopkins astrophysicist Brice Ménard produce the first complete all-sky ultraviolet map, with no gaps; roughly one third of the sky, including much of the galactic plane, was never observed in UV and was estimated by the model. The team merged public data from about 38,000 NASA GALEX observations plus NASA Swift and South Korea's FIMS/SPEAR, while Claude coordinated multiple agents to gather, rescale, cross-calibrate and fill the data, then added UV brightness for about 119 million stars derived from ESA Gaia visible-light measurements. In tests where already-observed areas were masked and refilled, estimates differed from real measurements by about 10%; every pixel is labelled observed or predicted with an uncertainty estimate, though some commenters questioned calling a map one third estimated "complete".
