This is a space travel simulator application. Using 3D stellar position data, you can experience realistic space travel. You can board a spacecraft that can fly billions of times faster than the ISS (International Space Station) and take an interstellar flight. During the flight, the positioning of stars changes, and familiar constellations are transformed into novel, never-before-seen shapes.
