Journey across the entire observable universe, from the Moon to the relic light at the edge of all we can see. Space is an interactive 3-D atlas of the cosmos. Every object is placed in its true position in the sky and at its real distance, on a scale that lets the Moon and the cosmic horizon share one navigable space. Tap anything to discover how far back in time you are seeing it, because the further away an object is, the older the light reaching your eyes. EXPLORE IN 3-D Drag to orbit, pinch to zoom, and tap any object to inspect it up close. Glide past planets, stars, nebulae, galaxies, black holes and quasars rendered from real NASA and ESO imagery. LOOK BACK IN TIME Light takes time to travel. Each object reveals its light-travel time from Earth: see the Sun as it was 8 minutes ago, Andromeda 2.5 million years ago, and the cosmic dawn 13.8 billion years ago. A LIVING SOLAR SYSTEM Watch the planets orbit on real elliptical paths, with moons, asteroid and Kuiper belts, and comets streaming twin tails. 130+ CURATED WONDERS A hand-built catalogue spanning planets, famous stars, exoplanets, nebulae, galaxies, galaxy clusters, neutron stars, black holes, quasars and the cosmic web, each with facts, properties and distances verified against NASA, ESA and Gaia data. LIVE FROM NASA Watch the International Space Station circle the 3-D Earth in real time, see the asteroids passing Earth today, follow the Sun's space weather, and stream the nearest confirmed exoplanets from the NASA Exoplanet Archive into their true positions in the sky. COSMIC DROPS A new interactive tool unlocks every month, from your Cosmic Birthday star to the phases of the Moon. JOURNEY THROUGH TIME Sit back for a guided tour outward from the Moon to the beginning of time, narrated by the light of each milestone along the way. LAUNCH FROM EARTH Choose a destination and ride a spacecraft there on a real gravity-turn launch: lift off, accelerate, cruise and arrive. FULLY BILINGUAL, ON IPHONE AND IPAD Complete English and Arabic support, with right-to-left layout. Switch languages anytime. Designed for iPad as well as iPhone, in every orientation. COSMOS PRO The free app shows ads. Cosmos Pro is a one-time purchase that unlocks Launch from Earth, the guided Journey Through Time, Live from NASA, Explore and the Cosmic Timeline, and the Cosmic Quiz, and it removes ads.
