WhereIsM13 and .jar files

WhereIsM13 is a great 3d visualization application of deep sky objects! You can see where these objects lie in our Galaxy along with their physical properties.

There are different download options according to the operating system.
For linux users download the .zip version which includes a .jar file that can be run by double clicking (well, not in my case…although I changed the properties so as to be executable). If not, then you can easilly run it by typing:

$ java -jar /path/to/file.jar

(there is no need for the file to be executable!).
