The `<tc:columnPanel/>` tag creates a panel space under each column. The content may be further information about the entries. This is the content of the column panel. Here e.g. can be placed some information about each entry, in this case over the planet or moon. It was discovered by #{object.discoverer} in the year #{object.discoverYear}. In this example there is a combination with the bootstrap classes to show either the discoverer and the year as a column, or on small displays in the panel after each row. See also the styling example.
