What is Celestia?

Celestia is an astronomy and planetarium program developed by Chris Laurel that allows users, especially students and educators, to view the universe and its galaxies in 3D. The software enables the user to explore space, get to know the solar system and learn about celestial bodies through the computer.

The program utilizes the OpenGL, or Open Graphics Library, application programming interface (API) to render images in 3D. Users can get a closer look at the planets in the solar system, including their moons, such as Jupiter and her famous moons Europa and Io; or Mars and Phobos. The user is also able to view the Valles Marineris rift valley of Mars, or the cracks on the surface of Europa.

The program also allows users to look through the Hale Telescope atop the Palomar Mountain, get a closer look at the Earth’s magnetic field, watch Apollo 11 land on the Moon, view the solar and lunar eclipse phenomena, and explore Saturn, its rings and its moons.

Celestia is software that developed as a multi-platform program, which make it compatible with Mac OS X, Linux and Windows.
