Open Source Astronomy Software

Stellarium renders 3D photo-realistic skies in real time with OpenGL. It displays stars, constellations, planets, nebulae and others things like ground, landscape, atmosphere, etc.

SkyChart is a software to draw chart of the night sky for the amateur astronomer from a bunch of stars and nebulae catalogs. See main web page for full download. This software is part of a full suite for astronomical observation: https://sourceforge.net/projects/ccdciel/ https://sourceforge.net/projects/indistarter/ https://sourceforge.net/projects/eqmodgui/ Requirement: https://sourceforge.net/projects/libpasastro/ See also: https://sourceforge.net/projects/indi/

Gpredict is a real-time satellite tracking and orbit prediction application. Gpredict can track an unlimited number of satellites and display the data in tables and various graphical view.

Celestia is an application for real-time 3D visualization of space, with a detailed model of the solar system, over 100,000 stars, more than 10,000 galaxies, and an extension mechanism for adding more objects.

Java based astronomical logging software which stores it's data in a free and open XML based format (OpenAstronomyLog). Discontinued project: Please check out the fork: https://github.com/capape/observation-manager for an updated version

This J2ME soft has data about Messier objects, galaxies, open and globular clusters and nebulas. Allows you to make an observation plan according to your interests, see Moon Phases of 2008 and Local Sidereal Time and Julian date. nochesky.googlepages.com

Gridder is a group of portlets that simplify the use and administration of grid services. Especially for job submission management. Gridder also extends and documents the functionality of the OGCE Bundle. It is plenty of useful documentation.

Ciclope Astro is a Web 2.0 application to control an astronomical observatory (telescopes, cameras, domes, etc.). It contains other tools as album (folksonomy & votes), forum, news (RSS), karma system. Developed using the Google Web Toolkit framework.

Ciclope Planetarium is a web-based planetarium that provides a simulation of the sky from any location at any time and date. Developed using Google Maps API & AJAX. Available in PHP & J2EE. Integrated in the Ciclope Stars project (www.ciclope.info/stars)

JPARSEC is a Java Package of Astronomical Resources for Standard Ephemerides Calculations, focused on accuracy, documentation, 2D/3D charts, realistic planetary rendering, and Astrophysical modeling. For source code visit http://conga.oan.es/~alonso/

python, SExtractor. A python module to read, write and manage SExtractor catalogs.

Java version of Stellarium.

GLNebula is a program designed for the real-time visualization of planetary nebulae models produced by photoionization codes. It uses camera-oriented quads and point sprites to achieve real-time speeds, also provides free camera movements.

La P.A.P.A. (Python Alternative for Programming Astrophysics) want to give an alternative to the astrophysicists (and any one that use RSI-IDL) for start programming in Python using similar functions as IDL and at the same time learn the power of Python.
