See the night sky in unique brilliance, travel to the stars and to strange, new galaxies, land on celestial bodies or orbit the Earth in real time. Plan your observations of the sky and control your telescope. Enjoy the many new features, the modern interface and a particularly simple operation!

Explore the night sky
Virtual planetarium to simulate the sky, with impressive representation of the movement of all celestial bodies and constellations. Exact calculation of the position of celestial bodies based on the latest scientific data – for the current time, for tomorrow night or any other time between 4713 B.C. and 9999 A.D. Visualization of the apparent motion of the sun, planets, moons, comets and asteroids in the night sky

Countless celestial bodies
Exact position calculation and motion simulation of over 100 million stars, 1 million deep sky objects, 1.2 million asteroids. Additional online access to the USNO B1.0 and Gaia DR3 catalogs with 1.8 billion stars.

Travel through space and time
Impressive flights through space to planets, moons, asteroids, spacecraft, stars and to distant galaxies, going even beyond the boundaries of the Milky Way. Simulation of astronomical events from fascinating angles with just one mouse click – it’s like you were there yourself. Breathtaking perspectives through three-dimensional representation of celestial bodies – also available for interstellar nebulae, star clusters and entire galaxies.

Explore the solar system
Positionally accurate landing on planets and moons to observe the sky from there, an orbit or a freely selectable location in the solar system. Visualization of the moons orbiting the planets. Observation of asteroids and comets on their way through space, highest accuracy of trajectoriy data by using numerical integration.
