Open Source Astronomy Software

A web atlas using the planetary body renderer, Xplanet. Explore the solar system. Overlay clouds, cities, weather forecasts, and more. Navigate by point and click. Search global databases.

A simple command to convert calendar dates to julian dates. Quite useful in timing situations where you need elapsed time between dates. Also useful for astronomy applications.

chklinks is a non-threaded Perl link checker. It helps finding broken links on your website. It does not raises many simultaneously connections for its job, run out of the resources and crash your system in a moment.

A set of cross-platform tools for connecting via TCP/IP to the VOEvent transient astronomy alert network. Tools include a receiver/broker, a sender/publishing tool, and a VOEvent message checker. Runs on Linux, Mac OS X and Microsoft Windows.

MOdular Virtual Observatory Interface for Radio astronomy, a GUI and API for creating Virtual Observatory (VO) applications and communicating between them.

Project Galileo at Sourceforge.net aims to provide developers a unique opportunity to develop open source software for an on-line telescope for schools across the UK. See http://www.projectgalileo.org.uk for more details.

TNF2 is based loosely on the original game TNF (The New Frontiers) http://www.geocities.com/TimesSquare/Castle/2979/ written and designed by Jerry Revell Jerry@starchase.demon.co.uk. Simply put the game is about space colonization. Each player runs a

This project offers a python binding to the libindi library. It uses the Simplified Wrapper and Interface Generator (SWIG). You may generate a PyIndi module which mainly defines an IndiClient class. This class could be used to build python scripts able to interact with indi servers using sendNew* methods and implementing new* methods of the BaseMediator class. PyQt applications may also be built on top of IndiClient, thus allowing rapid development of GUI Indi clients. Besides Python there are also bindings for node.js, Tcl (incomplete) and PHP (not useful). As application examples you will find a Python Websocket server with which you may build a web application interacting with Indi servers, and a simple PyQt application similar to the Kstars Indi Control Panel (was built as an exercise). Finally there is an equatorial mount 3D simulator written with Freecad and Python, planned to be connected with the PyIndi module. *** The pyindi-client binding has moved to github. ***
