The NEMESIS project aims to revisit star formation in the age of Big Data with the help of Machine Learning. We hope to improve our understanding of how stars form by delving into the plethora of amazing observational data that is available to researchers today. We also believe, that it is important to communicate new insights as we gain them and make them accessible to the general public. To this end we have created an automated tour of young stellar objects that you can view on your own PC at home using the Stellarium Planetarium software.
NOTE: This version is our first public release version and will be updated with further content in the future. Please check back here regularly if you want to check for updates.
Stellarium has a scripting engine which makes it possible to script this tour by making use of the Stellarium scripting API. The structure of the guided tour is as follows:
.
├── nemesis
│ ├── images
│ └── includes
│ ├── common.inc
│ ├── credits.inc
│ ├── image_meta.inc
│ ├── intro.inc
│ ├── main_show.inc
│ ├── outro.inc
│ └── source_list.inc
└── NEMESIS_tour.ssc
The main source file NEMESIS_tour.ssc is visible in the Stellarium scrips manager and can be run directly via the Stellarium GUI. The remainder of the files are hidden from the end user.
In order to run the tour directly from within Stellarium it must be installed in the scripts directory of your Stellarium installation. Please consult the Stellarium manual to figure out the default installation directory in your computer. The following instructions are based on the information in, and partly copied from the Stellarium User Guide (version 23.4) and are listed here for your convenience. If you run into any problems please consult the official Stellarium User Guide, Chapters 2.3, 5.1-5.2, and 17 or open a new issue here in this GitHub repository. For manual installation please follow the instructions below.
NOTE: We plan to provide installation wizards in the future, but for now only manual installation is available.
First download the latest version of the tour from the Releases or clone this GitHub repository to your computer.
To manually install the NEMESIS guided tour, you must copy the NEMESIS_tour.ssc script and all files and subdirectories in the nemesis folder into the scripts directory inside your Stellarium installation directory.
Linux
It is recommended to install all resource files to the User Data Directory. This should be located in your $HOME directory. Move the above mentioned files to $HOME/.stellarium/scripts.
It is also possible to install the scripts directly into the scripts directory in the installation directory of Stellarium. On Linux systems Stellarium is usually installed in the share/stellarium sub-directory of the installation prefix. Usually one of the following locations are possible:
/usr/share/stellarium or /usr/local/share/stellarium
macOS
On macOS the installation directory can be found inside the Stellarium.app application bundle. See The
Anatomy of macOS App Bundles or Bundle Programming Guide for more information.
Windows
On Windows the default installation directory is located at C:\Program Files\Stellarium\. However, this can be changed by the user during installation. If you have installed Stellarium at a custom location, please locate that directory before moving on.
Inside the Stellarium installation directory locate the scripts directory and copy the NEMESIS_tour.ssc file as well as the nemesis folder into it. If Stellarium is currently running, please restart the application, to make it visible inside the scripts manager inside Stellarium.
You should now be able to run the tour.
TBD
Once you have installed the NEMESIS guided tour following the instructions above you should be able to run the script from inside Stellarium. Simply open the Configuration window, either through the graphical user interface, or by pressing the F2 key on your keyboard. Locate and click on the Scripts tab at the top of the dialogue window. Next scroll down the list on the left side until you find the NEMESIS_tour.scc entry and click on it. Finally click on the Play button in the bottom of the right side of the window.
