Planetarium On The Go

planetarium shows & telescope observations

let us take you on a journey to the stars

Planetarium On The Go is a digital portable planetarium with a fixed Dome, a semi-permanent portable construction with chairs for the spectators, traveling all over Greece and anywhere in the World if invited, providing a unique educational experience. Its main feature is the hemispherical projection screen 6m in diameter and 57 square meters in surface area!

It can be set up both indoors or outdoors and it is air conditioned with heating during the winter and cooling during the summer. The images are projected across the entire inner surface of the dome completely surrounding the audience, creating an impressive immersive environment.

Stargazing evenings only with telescopes.

With our new technology telescopes we can observe deep sky objects – star clusters, nebulae, other distant galaxies – even from urban environments.

Save images of the Cosmos directly to your mobile phone.

Around the World with Planetarium on the Go!

Every year we cover a distance longer than Earth’s perimeter – 40,000 km – bringing space exploration to every corner of Greece and anywhere in the World if invited!

By showing the fascinating discoveries in space exploration, it both inspires and educates people of all ages about our surroundings – the Earth itself and our place in the Universe.

Mechanical Ventilation:

With the use of air ducts fresh air is constantly entering the Dome with total air renewal every five minutes.
