Voyager for Mac

Program snapshot

Take a voyage through the stars with a planetarium-style navigator that recreates the cosmos in striking 3D. This application lets you leave Earth behind and inspect the Solar System and distant stellar fields with smooth, realistic simulations. The software’s catalog includes more than 2.5 million stars, so you can examine everything from nearby suns to far-off clusters.

Visual features and sample sights

Inspect well-known binaries such as Alpha Centauri or watch the long-term motions of Lyra’s famed "Double Double."
Jump to open clusters or bright constellations and view the sky as it would appear from locations like Vega or the Pleiades.
Browse a huge stellar database with detailed positions, magnitudes, and other catalog data for millions of stars.

An interactive Solar Neighborhood tool lets you set a radius in light-years to display all cataloged stars within that range and rotate the scene to study their three-dimensional arrangement.
Controls are designed to be approachable: you’ll pick them up quickly, but the depth of available options means you can spend plenty of time exploring advanced features.

Intended users and educational value

Useful for professional astronomers and students who need accurate, navigable star data for study or demonstration.
Also an excellent teaching aid for instructors and parents: a 3D, movable model of the Universe conveys spatial relationships far more effectively than text alone.

Alternatives and additional resources

Stellarium — an open-source planetarium application suitable for hobbyists and educators.
YouTube — free guided tours and video demos that give a quick sense of the visual experience.

Update notes

Version 4.5.5: adds compatibility with Snow Leopard.
