What happened
Brice Ménard, an astrophysicist at Johns Hopkins University and Anthropic researcher, used Claude Science to generate the first complete map of the sky in ultraviolet light. The process involved orchestrating multiple AI agents to gather, calibrate, and merge data from NASA's GALEX, Swift, and other missions. Claude Science then used machine learning inpainting to predict UV brightness for the roughly one-third of the sky never observed in UV, achieving an estimated accuracy within 10% of real measurements in validation tests.
Brice Ménard, an astrophysicist at Johns Hopkins University and a researcher at Anthropic, collaborated with Claude Science to produce the first complete map of the sky in ultraviolet light. The project aimed to address a long-standing gap in astronomical education, where previous UV maps were incomplete due to atmospheric absorption and satellite limitations.
The process began with Claude Science orchestrating a team of AI agents to search for and download publicly available UV surveys, including data from NASA's GALEX mission, which imaged about two-thirds of the sky. The agents worked in parallel to calibrate these datasets, removing glare from bright stars and ensuring internal consistency across different observation periods and instruments.
To fill the roughly one-third of the sky that had never been observed in UV, Claude Science employed a machine learning technique called inpainting. The model learned the relationship between UV brightness and observations at other wavelengths (visible, infrared, radio) from the mapped regions and applied this to predict the missing data. Validation tests showed the model could estimate hidden data to within about 10% of real UV measurements.
The collaboration involved iterative refinement over several days. Ménard identified artifacts in the initial map, such as faint circles from GALEX observations caused by residual atmospheric glow. Claude Science traced the issue and corrected it across all 38,000 observations, demonstrating the system's ability to debug and refine complex data processing pipelines based on human feedback.

Why it matters
This project demonstrates a practical application of AI agents in scientific research, specifically in handling the tedious, lower-priority data processing tasks that often prevent scientists from completing useful educational or reference tools. By automating the and inpainting of astronomical data, Claude Science allowed a single researcher to complete a project that would traditionally require weeks of painstaking manual work. The resulting map serves as a valuable educational resource for understanding galactic structure in UV wavelengths, highlighting how AI can accelerate scientific discovery by managing complex, multi-step data workflows.
This case study illustrates the practical utility of AI agents in scientific research, particularly for tasks that are time-consuming but essential for creating comprehensive datasets. By automating the and merging of multi-source data, Claude Science reduced the barrier to entry for producing high-quality scientific maps.
The use of inpainting to fill gaps in astronomical data represents a significant application of machine learning in astrophysics. It allows researchers to create complete visualizations of the sky, which are crucial for education and further analysis, even when direct observations are unavailable.
The project highlights a shift in how scientific work is conducted, with AI handling the 'patient labor' of data processing while researchers focus on high-level guidance and interpretation. This could lead to more efficient use of scientific resources and the completion of projects that were previously deprioritized due to time constraints.
