Confederation of open source projects in Astronomy

OpenAstronomy is a collaboration between open source astronomy and astrophysics projects. It currently includes the following projects: Astropy, SunPy, yt, ChiantiPy and Julia Astro.

The range of topics covered by these projects is wide: Astropy is a general library for astronomy, providing common tools such as celestial coordinates, image processing, tabular data reading and writing, units and support for astronomy-specific file formats. SunPy provides utilities for obtaining and representing solar physics data, with clients for some of the largest online solar physics data archives and solar specific analysis and visualisation code. The yt project is a Python package for analyzing and visualizing volumetric, multi-resolution data. ChiantiPy is a Python interface to the CHIANTI atomic database, which allows users to characterise the properties (temperature, density, velocity) of observed stars from spectra. JuliaAstro is an organization that coordinates the development of common astronomy packages for Julia (These libraries are similar in scope to Astropy and often share underlying C implementations.).

As a single organisation, we aim to strengthen collaborations between the different sub-organisations, and at the same time increase the awareness among our users of the capabilities of our "sister" projects.
