Stellarium for MAC
Free, open-source planetarium for your Mac: a realistic night sky with stars, planets, constellations and deep-sky objects.
Stellarium Overview
Stellarium is a free planetarium that shows a realistic sky in 3D, just as you would see it with your eyes, binoculars or a telescope. Pick any place on Earth and any date and time, and Stellarium shows the stars, planets, Moon, constellations and nebulae for that moment, with a realistic atmosphere, sunrise and sunset and the Milky Way. It has a catalogue of hundreds of thousands of stars, sky cultures from around the world, and tools for telescopes and eclipses. Stellarium is developed by a worldwide team of volunteers and is used in planetariums, schools and by amateur astronomers.
Stellarium is free and open source under the GPL-2.0 license. The current Mac version, 26.3, is a universal app for Apple Silicon and Intel Macs and needs macOS 11 or later; an older version is still offered for macOS 10.13 and later.
