AstroAviBrowser is a small tool for astronomy imaging capture/treatment. It allows you to open a video file, select the good frames, and save the new sequence in a new video file using the desired codec.
astromake is a utility intended to make installations of some common astronomical packages (in binary form) easy. In practice it is a shell script that with the aid of makefiles wraps around rpm's, tarballs and debian packages, currently the three most common package formats.
AstroMD is a visualization package developed in the Cosmo.Lab framework with the specific object of supporting visualization and analysis of astrophysical three dimensional structures. Astrophysical data, in fact, have peculiarities that make them different from data coming from any other kind of simulation or experiment. Therefore they require a specific treatment.
Astronomical Python - Promoting the Development & Use of the Python Programming Language in Astronomical Research
BOTEC is a simple astrophysical and orbital mechanics calculator, including a database of all named Solar System objects.
Colorspec takes as input a digital spectrum ASCII file, space delimited in two columns with wavelength from low to high in Angstroms and relative flux in any units. It produces by default an 800x50 PPM format 24-bit RGB image which can be displayed by most image viewers, and modified as needed or converted to other formats with image processing programs such as Gimp.
Exoflight is a spaceflight simulator. The player can fly several space vehicles and rockets, travel to the bodies of the solar system, and complete a variety of missions. It includes several spacecraft from history and the future, including the Apollo spacecraft, Saturn V, and Space Shuttle.
fewbody is a software package for doing small-N scattering experiments, licensed under the GNU GPL. "fewbody" can handle an arbitrary number of stars, and understands arbitrarily large hierarchies.
glnemo is an interactive visualization program for snapshots, based on the Qt library from Trolltech. You can zoom in/out, rotate, scale, translate, save a screenshot, select different particles and plot them in different blending colors.
Global Village is a GNOME application designed to place a GUI onto the CLI interface of Xplanet.
Gnome Predict is a satellite tracking program for Gnome.
GRALE is a library to model gravitational lenses and invert gravitational lens systems based on the observed images.
Henry is an educational astrometry utility for performing calculations based on a Hertzsprung-Russel (H-R) diagram, such as spectroscopic parallax for working out the distance to a given star. Unlike many other solutions that use in-built images for their H-R diagrams, Henry plots data directly from the European Space Agency's HIPPARCOS catalog, allowing increased accuracy while also giving students greater room to experiment by exploring the catalogue themselves.
INDI is the Instrument-Neutral-Distributed-Interface control protocol. INDI has many advantages including loose coupling between hardware devices and software drivers. Clients that use the device drivers (like KStars) are completely unaware of the device capabilities. In run time, clients communicate with the device drivers and build a completely dynamical GUI based on services provided by the device. Therefore, new device drivers can be written or updated and clients can take full advantage of them without any changes on the client side.
KAstrometry is for the KDE Desktop Environment. It is written in Python. It aims to be a good tool to make measurements of objects in space from images taken by CCD cameras. Such measurements might be used to find orbits of astroids or record the brightness of variables stars.
Moon Tool displays information about the current state of the moon and sun.
moontool displays an icon with the current phase of the Moon on an OpenLook or SunView screen.
partiview is a program that enables you to visualize and animate particle data. partiview runs on relatively simple desktops and laptops, but is mostly compatible with its big brother VirDir.
pngphoon is intended as a successor to xphoon. It draws the actual phase of the moon into a png file for desktop integration.
PyNOVAS offers a collection of functions and applications for calculating the positions of the sun, moon, planets and other celestial objects.
radial calculates the radial velocities of both stars in a binary system.
SAOimage is a utility for displaying astronomical images in the X11 window environment. It was written at the Smithsonian Astrophysical Observatory by Mike Van Hilst in 1990 and is now maintained by Doug Mink. Image files can be read directly, or image data may be passed through a named pipe (Unix) or a mailbox (VMS) from IRAF display tasks.
Satellitarium is a graphical application that predicts the position of artificial satellites and displays them against the sky background.
SkyDome is a tool to demonstrate the location of stars, planets, constellations, and the Milky Way during Earth's rotation. Besides the optical view, various other star maps are incorporated from satellites like COBE, EGRET, and IUE, making the multi-wavelength Milky Way visible to the user.
SkyViewer is an OpenGL-based program written by Nicholas Phillips to display HEALPix-based sky maps from FITS format files. The program will display sky maps on a 3D sphere or a 2D Mollweide projection. Real time panning and zooming are supported, as are rotations of the 3D sphere (if you have a fast graphics card).
Solar reads a line list from the Moore Tables of the Rowland Atlas of the Sun and creates a spectrum based on the wavelength and equivalent width of the tabulated features. It is useful for creating illustrations of spectra that have selected lines.
SolarBeam is a desktop application for drawing solar diagrams. You supply the geographical position, and it draws a diagram showing the Sun's trajectory over your location at various times of the year. It also shows the times of sunrise and sunset.
Starbase is a set of filter programs and an ascii table format for UNIX. The current release contains over 95 programs for manipulating data tables.
Starblinker allows you to easily search for new stars in your astronomical photos.
SunSky uses the Utah sun/sky model to draw plots
of the entire sky, or a specific window of the sky, for a given location, time, and view
The TABLES package sits alongside STSDAS and provides tools and libraries for working with tabular data.
TRIP is a general computer algebra system dedicated to celestial mechanics. It includes a numerical kernel and has interfaces to gnuplot and xmgrace.
Virtual Moon Atlas
Virtual Moon Atlas is a program that allows users to observe and study the moon and its surface. It can visualize the Moon aspect for every date and hour and pilot computerized telescopes on the Moon surface. Read more
WIP is an interactive package with a simple to use command line user interface used to produce high quality graphical output. WIP was developed as part of the Berkeley-Illinois-Maryland Association (BIMA) project.
wmJupiter shows you the actual distance of Jupiter in astronomical units (AE) and when the red spot crosses (which is a weather feature on jupiter).
wmSolar shows you the solar system viewed from top (90° heliocentric).
