  abstract: >-
    The Astropy Project supports and fosters the development of
    open-source and openly developed Python packages that provide
    commonly needed functionality to the astronomical community. A key
    element of the Astropy Project is the core package astropy, which
    serves as the foundation for more specialized projects and
    packages. In this article, we summarize key features in the core
    package as of the recent major release, version 5.0, and provide
    major updates on the Project. We then discuss supporting a broader
    ecosystem of interoperable packages, including connections with
    several astronomical observatories and missions. We also revisit
    the future outlook of the Astropy Project and the current status
    of Learn Astropy.  We conclude by raising and discussing the
    current and future challenges facing the Project.

      The Astropy Project supports and fosters the development of
      open-source and openly developed Python packages that provide
      commonly needed functionality to the astronomical community. A
      key element of the Astropy Project is the core package astropy,
      which serves as the foundation for more specialized projects and
      packages. In this article, we provide an overview of the
      organization of the Astropy project and summarize key features
      in the core package, as of the recent major release, version
      2.0. We then describe the project infrastructure designed to
      facilitate and support development for a broader ecosystem of
      interoperable packages. We conclude with a future outlook of
      planned new features and directions for the broader Astropy
      Project.

    abstract: >-
      We present the first public version (v0.2) of the open-source
      and community-developed Python package, Astropy. This package
      provides core astronomy-related functionality to the community,
      including support for domain-specific file formats such as
      flexible image transport system (FITS) files, Virtual
      Observatory (VO) tables, and common ASCII table formats, unit
      and physical quantity conversions, physical constants specific
      to astronomy, celestial coordinate and time transformations,
      world coordinate system (WCS) support, generalized containers
      for representing gridded as well as tabular data, and a
      framework for cosmological transformations and
      conversions. Significant functionality is under active
      development, such as a model fitting framework, VO client and
      server tools, and aperture and point spread function (PSF)
      photometry tools. The core development team is actively making
      additions and enhancements to the current code base, and we
      encourage anyone interested to participate in the development of
      future Astropy versions.
