MESA: Modules for Experiments in Stellar Astrophysics -- a set of thread-safe fortran 95 libraries for stellar astrophysics, including physics (e.g., eos, opacities, nuclear nets) and algorithms (e.g., ODE solvers). Available by svn checkout or as zip file. See project webpage (http://mesa.sourceforge.net/).
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.
Siril is an astronomical image processing software for Linux.
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
SkyNET is a sky chart program for .NET
Note: This project is no longer maintained. A newer version of the program is at https://code.google.com/p/digest2/. Statistical ranging for short arc moving object astrometry. Accepts atstrometry in MPC 80 charcater observation format, rates objects on likelyhood that they are yet-unknown near Earth objects.
Command-line tools for astronomy and astrophysics
Command-line tools for astronomy and astrophysics, written in Fortran.
C++ code for a N-Body Simulation. Computational Physics with graphics.
Application for logging, planning, and searching astronomy observations. Written in Python/Tkinter with support for xmlrpc/SOAP as a secondary goal.
CELUI Is a general purpose C++ OpenGL cross-platform GUI framework that allows to create animated and rich user interfaces for simulations and games.
Gnorbits is an open source 3-D orbit program. It supports multiple bodies of varying masses and initial velocities, using a GTK interface.
Experimental OpenGl night sky rendering by making full use of modern PCs hardware. Writing another planetarium is crazy? It's Glunatic!
JOrrery simulates the motion of planets moving under gravity. It comes with a number of initial "scenarios" you can run, such as "The solar system", "Earth & Moon" etc. You can also add more planets during a simulation.
This project is intended to develop a suite of tools that enable use of the Meade Deep Sky Imager in LINUX.
metric2energy reads in an arbitrary metric and algebraically calculates the christoffel symbols, Riemann, Ricci, and Einstein tensors from it, saving the result in a LaTeX source for beautiful pdfs.
MISS is a software simulation of the control room of the International Space Station. It is intended to be both entertaining and educational, aimed at high school students. Various pre-configured and random events encourage interaction and groupwork.
IRAF image server for Mac OS X (pure Cocoa).
PyXPA is a Python interface to the XPA library (http://hea-www.harvard.edu/RD/xpa/ developed by the SAO/HEAD R&D Group (http://hea-www.harvard.edu/RD/)).
This is a linux project for who is a bit tired to have stupid-one camera-not networkable ccd control software. Multi-tire via tcp/ip and multicamera (i.e. one primary camera and a secondary one for guide/seek)
Satellite Tracking Web Service
Simulation of star movements with great visualizations of flights through star fields.
StarMap 3D: the project aims to offer a fast and easy consultation of stellar systems
Software to support TASS, The Amateur Sky Survey. We are taking photometric measurements of all stars in the sky in several filters measurements repeated frequently to allow detection of variable stars
The Universe Simulator project's goal is to provide a set of libraries for simulating all known and understood physical phenomena.
For the direct and detailed analysis of supernova spectra.
