The Astropy Project is a community effort to develop a core package for astronomy using the Python programming language and improve usability, interoperability, and collaboration between astronomy Python packages. 

Astropy was one of the projects used in the LIGO gravitational waves discovery. 

Astropy is used by a large and growing number of organizations and projects worldwide, including: the Association of Universities for Research in Astronomy (AURA); the Hubble Space Telescope and James Webb Space Telescope pipelines, including many instrumentation support, observation planning, and data analysis codes; science pipelines for the forthcoming Large Synoptic Survey Telescope; many European Southern Observatory (ESO) instrument pipelines, including (e.g.) the MUSE Python Data Analysis Framework; Gemini Observatory’s science, data quality, and reduction pipelines; the pipeline framework for the Cherenkov Telescope Array; major SDSS surveys, including MaNGA, APOGEE, and eBOSS; codebases for the SAMI Galaxy Survey and the Close AGN Reference Survey; and Astropy ’s table and units functionality is also used by organizations outside of astronomy, including the Norway Mapping Authority.

The core astropy package contains functionality aimed at professional astronomers and astrophysicists, but may be useful to anyone developing astronomy software.
