The purpose of this document is to provide a brief overview, installation and user tips for the OpenSpace Program.

OpenSpace is a free, open-source astronomical visualization software that allows you to explore the universe from your computer! Imagine flying through our solar system, past distant galaxies, to the edge of our visual experience.

You can observe real-time satellite trajectories, land on planets, and zoom in on objects with stunning detail. OpenSpace uses actual scientific data, making it an incredibly accurate and immersive tool for learning about celestial objects and phenomena. It’s like having a planetarium, observatory, and spacecraft all rolled into one, right at your fingertips!

OpenSpace – Information and Setup Guide

Stockton Astronomical Society www.stocktonastro.org

It is open-source. This means you can download and use it without any cost. It's developed as a research project by NASA with contributions from institutions like the Hayden Planetarium, American Museum of Natural History and Linköping University, and its primary goal is to make scientific data accessible for public visualization and education.

OpenSpace is not a replacement for Stellarium, Sky Tools or other earth-bound astronomy applications … but is a good educational companion for presentations and fun.

OpenSpace – Data Sources

OpenSpace acts as a platform to pull together and visualize scientific data from leading NASA projects, observatories and institutions, ensuring accuracy and scientific rigor.

Images and data from;

    • Hubble Space Telescope: galaxies, nebulae, and other deep-sky objects
    • Chandra X-ray Observatory: black holes and supernova remnants
    • Gaia Mission (ESA): astrometric data for billions of stars, mapping their positions, distances, and motions in 3D
    • NASA Solar System Treks: maps and data planetary bodies in our solar system
    • NOAA Science On a Sphere: Contributes Earth-related data and visualization
    • Satellite trajectories: Shows the paths of actual satellites in orbit

Simulations and Models: Beyond direct observations, OpenSpace also uses data from scientific simulations and models to represent phenomena that are difficult or impossible to observe directly, such as:

    • Cosmological simulations: To visualize the large-scale structure of the universe, including the Big Bang and the evolution of galaxies.
    • Heliophysics content: To visualize dynamic energy emissions from the Sun and their effects on the solar system.

OpenSpace – Installation and Setup continued

The download may take 10 to 15 minutes based on your internet speed … so go make coffee

Stockton Astronomical Society www.stocktonastro.org

The downloaded file name will be “OpenSpace-0.20.1.zip”

Double click the file and extract the contents to a folder on your hard drive.

The executable file (the actual program) is located in the ‘bin’ folder and is called “OpenSpace.exe”.

OpenSpace – Using the Application

Hint; I made a ‘shortcut’ of the OpenSpace.exe and placed it on my desktop for ease of use

Stockton Astronomical Society www.stocktonastro.org

Double-click on the OpenSpace.exe

Two windows will open;

Click to Open

Dialog window showing the data loads and status, do not close this, you can ignore it

Launch window to start open the application

OpenSpace – Using the Application

The ‘Start’ button initiates the load of the program. This will take some time as the application is downloading data from across the internet. This can be seen in the scrolling information in the dialog window.

Stockton Astronomical Society www.stocktonastro.org

The application loads showing a rendering of the Earth and ‘Realtime’ on the clock

The Launch window will be replaced by the ‘OpenSpace application screen

When the load is complete the dialog window will stop scrolling and a rendering of the Earth will appear
