Astropy ( is a package intended to contain much of the core functionality and some common tools needed for performing astronomy and astrophysics with Python.

Releases are registered on PyPI, and development is occurring at the project's github page.

For installation instructions, see the online documentation or docs/install.rst in this source distribution.

For system packagers: Please install Astropy with the command:

$ python --offline install

This will prevent the astropy_helpers bootstrap script from attempting to reach out to PyPI.
