Knowledge panels are information boxes that appear on Google when you search for entities (people, places, organizations, things) that are in the Knowledge Graph. They are meant to help you get a quick snapshot of information on a topic based on Google’s understanding of available content on the web. Similar “Knowledge panels” are available on other search engines too.
