& Science

Access to the ultraviolet spectral range (UV) is for astrophysical research in virtually all areas of fundamental importance. Because of the transmission characteristics of the atmosphere, astronomical observations in this spectral region are not possible from earth and therefore have to be from a spacecraft. Public Telescope is a universal UV Observatory for modern astrophysics in space, mainly for spectroscopy. The use ranges from the study of bodies in our own solar system over to the stars and planets in our galaxy and to distant galaxies.

Children and young people are very much interested in the universe, space and technology. Our modern western society needs both - technically and culturally highly educated and confident young people to secure and to expand our standard of living and to be successful in global competition. Public Telescope offers the best opportunities for students to explore the universe, develop important skills and to learn how to deal with technologies that will determine their daily life tomorrow. Applications range from learning about satellite technology to study the theories of Newton and Einstein up to the observation of atomic and astronomical objects and processes.

Private Astronomy

Public Telescope aims to give private astronomers the opportunity to observing celestial objects outside the Earth's atmosphere. Turbulence in the Earth's atmosphere and light pollution limit the sharpness and the quality of astronomical acquisitions. The applications range from observing planets in the solar system on to measuring stars in the Milky Way and up to the studying transient objects in the local Universe.
