Astropy provides a common framework, core package of code, and affiliated packages for astronomy in Python. Development is actively ongoing, with major packages such as PyFITS, PyWCS, vo, and asciitable already merged in. Astropy is intended to contain much of the core functionality and some common tools needed for performing astronomy and astrophysics with Python.
This research made use of Astropy, a community-developed core Python package for Astronomy (Astropy Collaboration, 2013). Paper: 2013A&A...558A..33A
