Friend of mine was asking about how to remove EarthDesk, an app she installed earlier.
EarthDesk replaces your Macintosh desktop picture or Windows wallpaper with a stunning dynamic image of our planet continuously updating in the background while you work.
Searching the web, I found the answer:

AUTOMATIC UNINSTALL
There is an uninstall button located in the License Tab of the EarthDesk System Preference Pane. If you have partially removed EarthDesk, it is easiest to reinstall the software and use this button. In rare cases, there may be premissions errors on your machine which prevent the automatic uninstall from working. Please use manual uninstall in these cases.
