From the webpage:
The SunPy project is a free and open-source software library for solar physics.
SunPy is a community-developed free and open-source software package for solar physics. SunPy is meant to be a free alternative to the SolarSoft data analysis environment which is based on the IDL scientific programming language sold by Exelis. Though SolarSoft is open-source IDL is not and can be prohibitively expensive.
The aim of the SunPy project is to provide the software tools necessary so that anyone can analyze solar data. SunPy is written using the Python programming language and is build upon the scientific Python environment which includes the core packages NumPy, SciPy. The development of SunPy is associated with that Astropy. SunPy was first created in 2011 by a small group of scientists and developers at the NASA Goddard Space Flight Center on nights and weekends.
Future employers will be interested in your data handling skills. Not whether you learned them as part of a hobby (astronomy), on your own or from a class. From a hobby just means you had fun learning them.
I first saw this in a tweet by Scientific Python.
