An artist's impression is a representation of a concept or idea created by an artist using their creativity and imagination. It is typically a visual depiction of something that has not yet been created or built, or of something that exists but is not directly observable or photographable, such as a distant planet or a historical event. Artists' impressions are often used in various fields, including architecture, space exploration, scientific research, and marketing, to convey a sense of what something might look like or how it might function. They can be based on existing designs or descriptions, but they are not meant to be precise depictions and are instead intended to convey a general idea or feeling.
