The celestial sphere is a representation of how the entire sky looks as seen from Earth. It is like an imaginary sphere surrounding the Earth, with the stars and other celestial objects projected onto its surface. It is a tool used by astronomers to describe and locate celestial objects. The concept of the celestial sphere is still used today, even though we now know that the stars are not actually arranged in a sphere around the Earth.
