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.

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

PP3 creates celestial charts. It generates resolution independent sky maps of very high graphical quality. They can be used for example as illustrations in books or on web pages. Databases are included but you may use own data if you wish.

Nowadays the idea of a music of the spheres, or a cosmic music that descends from the planets seems more like poetic philosophy than anything scientific. However, when the scientist Kepler discovered special principles about planetary motion, he also reconsidered the music. Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity. The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a Java Virtual Machine (Rev 1.5 or greater). JAVA 2, system independent. Purpose:to encourage research in harmony in astronomy, math and music. Obstacles:math, DSP/synthesis, networks, astronomy. Features:audio, database, graphics Technologies: Telnet, .WAV audio, oggvorbis, other audio

A high performance visualization tool for stars and particles able to run on Beowulfs. Rendering step is implemented separately and optimized for SSE, compatible with OpenGL. Navigation mechanism with quaternions. Ten color maps, sobel contour detect

This library is a Fortran 95 gnuplot interface for some Unix like OS'es. This provides some routines that enables direct access of a child gnuplot session from a Fortran 95 program. You will need a copy of fortranposix to make this work.

AQUYNZA is a set of C++ libraries, sample programs and doc's for the modelling, visualization and persistence of 3D environments. Its modular and highly portable. Its primary objective is helping to learn (and teach) computer graphics. (code in SPANISH)!

Multiplatform and Open Source project for astronomical image processing

General purpose scientific framework and its astronomy samples

The Gerbil project moved to http://www.gerbilvis.org Please visit us there for up-to-date information and current software releases!

Experimental OpenGl night sky rendering by making full use of modern PCs hardware. Writing another planetarium is crazy? It's Glunatic!

Jaude is "Java pour les Astronomes Utilisateurs de Detecteurs Electroniques". Jaude is Eclipse RCP and plugin based. So it will provide an Eclipse interface for JSky library (http://archive.eso.org/JSky/).

L.E.I.C.A. (Long Exposure Internet CAmera) is an application that takes input from your webcam, or v4l2 device, and makes a long-exposure image. Until now there's only a python binding for this app, soon there will be a C/C++ SDL one

Application for astronomical photos processing. Intended mainly for amateur astrophotography, for catching "beauty of the universe" rather than some serious scientific data. Includes automatic image registration.

PODWG is a Wallpaper Generator from various "Picture Of the Day" sources such as NASA's "Astronomy Picture Of the Day".

ProStack - a platform for image processing and analysis. It implements various image processing methods as separate modules, that can be joined in a complex image processing scenario by use of a graphical user interface. RPMs are available at https://build.opensuse.org/project/repositories/home:mackoel:compbio

Backend for scripts to control an SBIG ST-4 CCD camera.

SImg is astronomical image processing software for Linux. Some of the features are deconvolution (various algorithms), removing interferences, automatic shifting of images, computation of PSF and and a visualization tool.

Simulation of star movements with great visualizations of flights through star fields.

Siril is an astronomical image processing software for Linux. Dev here is stopped: as of 2013/02, Siril development has moved and is regaining activity here https://free-astro.org/index.php?title=Siril

Talon is a a fully automated open-source solution for automated telescope and observatory control. Talon controls all aspects of robotic astronomical observations, including telescope control, dome control, image processing, scheduled operations, and envi

A collection of Java ports of open source terrain and solar system generation packages. Code has been extensively refactored, extended and documented. GPL License with exception for required libraries.

Uranograph is a set of classes and methods written in Java for generating printable and viewable star charts based on different data sources. Currently the Lambert azimuthal equal-area projection is implemented. Output in SVG and PDF (with iText library)

Sombrero is a fast wavelet image processing and object detection C library for astronomical images. Sombrero is named after the "Mexican Hat" shape of the wavelet masks used in image convolution and is released under the GNU LGPL library.
