Yes, this is possible. I have included a link
to our documentation that further explains how to setup RSS feeds. You can setup the RSS feed by clicking on Administration >> Feeds & Notifications (Under Alternative Publishing). From here you can setup what kind of RSS feed you would like to create. After you have your RSS feed setup, you can place the RSS widget on a page.
Please let us know if you have anymore questions or concerns.
