GyVe (GalaxY ViEwer) is a visualization program for understanding the distribution of galaxies and clusters of galaxies.

It is a gnuplot library that gathers a set of functions to deal with problems of celestial mechanics. It allows one to easily accomplish tasks such as: - Converting orbital elements into Cartesian coordinates and vice-versa - Evaluate orbital position as function of the flight time and vice-versa - Plotting keplerian orbits easily

Android application that displays list of halachic/halakhic times for Jewish prayers (zmanim and zmanei tefillot).

Ham's Actor is a software for radio hams. Is a bundle of many functions and tools, so you just have to have one software. Functions: Log Book, GrayLine, satellite tracing, contesting, maps, callbook, and so on...

Hammurabi is a HEALPix-based tool for simulating observables such as polarized synchrotron and thermal dust emission from models of physical inputs such as magnetic fields, dust and electron distributions, etc. It is a modular C++ framework into which you can add your own models easily and then use it to perform the line-of-sight integration to compute the observables. See the wiki for installation and usage information. Please cite the original Waelkens et al. (2009) paper if you use hammurabi. This version of Hammurabi is deprecated and is no longer being supported. A new and improved version of Hammurabi (dubbed 'X') is available at : https://bitbucket.org/hammurabicode/hamx

Educational astrometry utility for plotting stars on a Hertzsprung-Russel diagram. Useful for learning about stellar spectra and properties and performing spectroscopic parallax calculations, as found in many high school physics courses.

Henry is an interface for Taylor 1.4.3 package (A. Jorba & M. Zou) and was written for master thesis to compute N-body problems (in Poincare variables) and MEGNO stability factor. Work is supported by Krzysztof Gozdziewski.

HSPI offers to the astronomer the possibility to capture pictures from the CCD camera in a fast and intuitive way, keeping under control all the instrumentation in posses. HSPI can control the CCD camera, the mount, the focuser, the filter wheel and the dome from a single interface, and not only this: these features can be added on as many observatories and instrumentations you want. HSPI is ASCOM and INDI compatible, so if you want to use particular setups like Linux computers connected with your instrumentation and control them from remote then HSPI is your choice! After a few clicks you can see the images coming from your cameras connected through Internet or your LAN. HSPI saves your pictures in various formats: Bitmap, FIT, JPEG, PNG, TIFF are the picture formats supported.

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

Analysis software for Nbody/SPH or SPH simulations (e.g. performed with Gadget II). See http://sourceforge.net/apps/wordpress/hyplot/about and http://sourceforge.net/apps/trac/hyplot/wiki for more information.

spice-dlm provides a seamless mechanism for IDL users to access the SPICE library from JPL/NAIF, providing ephemeris information for solar system objects and spacecraft.

INDI is an instrument neutral distributed interface control protocol that aims to provide backend driver support and automation for a wide range of Astronomical devices (telescopes, focusers, CCDs..etc). Project migrated to Github: https://github.com/indilib/indi

This project consist in a .NET/Mono assembly containing a simple INDI client and a WinForm that permits to connect to astronomical equipment INDI server, and to use drivers connected at it.

This project is no longer under active development. It has been superceded by the alignment subsystem which is now part of the main INDI project. This project provides an "alignment layer" driver to sit above INDI telescope drivers. This layer performs transformation services for telescope coordinates as they pass up and down to the underlying driver. The conversion matrices are computed from alignment datums passed down into the alignment layer. The N point alignment model can be used for both equatorial and alt azimuth mounts. The alignment database and coordinate conversion functionality is isolated in a separate class library module which can also be used to provide this functionality directly to INDI telescope drivers.

A Java library implementing the INDI distributed control protocol (http://indilib.org). Designed to easily implement new INDI Clients (graphical and not graphical ones), INDI Drivers and INDI Servers. We have started a complete overall of the project with many more drivers the staging site with the current development state can be found here http://indiforjava.sourceforge.net/stage/

This is a project to prove the existence of space travel by observing the international space station. This will include some history about non-believers, maths and a program to calculate the heigth and velocity of the ISS.

This projects hold software required for instrumenting an alt-az telescope mount. The required hardware is documented here (http://simonbox.info/index.php/astronomy). The software enables real time conversion from (measured) alt-az to ra-dec and manages a connection to Stellarium (http://www.stellarium.org/), which allows you to view where the telescope is pointing in a virtual planetarium.

JAlma is Java Astronomical Almanac.

he JAVA library is designed to read JPL DE/LE ephemerides (DE200, DE405, DE406, DE421, DE422, DE430, DE431, DE440 and DE441) and to calculated the position and velocity of the Sun, Moon, eight major planets and Pluto, also the earth nutations and the lunar librations if they are part of the ephemeris.

JFitsio is a Java library wrapping the CFITSIO library using the Java Native Interfaces (JNI) to provide acess to FITS files.

JAVA project represents the realization of modern astronomical algorithms related to the orbital movement of planets, satellites and small bodies in the solar system by solving Kepler's equation and additional astronomical and mathematical libraries

JOSAST ( Java Open Source Amateur Satellite Toolkit) is a set of java source code used for amateur satellite, hamradio and also astronomia activities ... Reusable package and complete software should be available.

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.
