It wraps optimized C code originally written for astrometry.net and is maintained as part of the Astropy project. The package enables efficient spatial indexing, coordinate transformations, and all-sky data binning\u2014essential operations for survey astronomy, cosmology, and large-scale sky analysis.\n\nThe package depends on numpy for array operations and astropy for coordinate handling. It provides compiled wheels for modern Python versions (3.10+) across macOS, Linux, and Windows platforms, reducing installation friction. With active maintenance and no known security vulnerabilities, it integrates directly into the Astropy ecosystem for researchers and developers working with celestial coordinate systems and large-scale astronomical datasets.","worth_installing":"Yes. Active maintenance, permissive BSD license, no security vulnerabilities, and pre-built wheels for modern Python versions make this a low-friction choice. Install it if you work with all-sky surveys, need efficient spherical pixelization, or are building within the Astropy ecosystem. The medium compile-time friction is offset by wheel availability and the package's role as a standard tool in observational astronomy."},"id":"astropy-healpix","links":{"html":"https://skillfed.io/packages/astropy-healpix","md":"https://skillfed.io/packages/astropy-healpix.md","pypi":"https://pypi.org/project/astropy-healpix/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-20","license_spdx":null,"license_treatment":"permissive","name":"astropy-healpix","python_support":"supports_current","summary":"BSD-licensed HEALPix for Astropy"},"popularity":{"monthly_downloads":274428,"position":8191,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.1"}
