If the databases are on the same server, you can just reference the table using the three-part name: database.owner.table

SELECT ... FROM mytable
UNION
SELECT ... FROM otherdatabase.ownername.othertable

OTOH, if the other database is on another server, you'll have to create a Linked Server and use that name of the linked server when referencing the other database:

SELECT ... FROM mytable
UNION
SELECT ... FROM linkedservername.otherdatabase.ownername.othertable
