A virtual artifact is a digital copy or simulation of something that is found in the real world, like a historic artifact or a piece of art. For example, say a museum has an ancient vase. The museum might create a digital version of this vase that people can explore and learn about online using a computer or a smartphone. It's like a 3-D picture of the vase, so you can see what it looks like from different angles and learn more about it without having to actually visit the museum where the vase is.
