Set against a haunting, atmospheric soundscape, the app shows planets and satellites in their correct positions, and offers mini movies, facts and other related tidbits.” - TNW “This jaw-dropping app provides a wholly interactive 3D model of our solar system, one that’s had me hooked for days. It’s the kind of thing you can imagine a science teacher using in the classroom of the future — except that we don’t have to wait.” - CNet “Zoom from Mercury to Pluto (which makes the cut in this app), passing each planet’s moons along the way. Because Solar Walk knows what time it is, the planets are in proper orientation to the Sun: Earth is dark where it is currently night and gradually lightens to daytime on the other side.” - NY Times "It's great for showing my students the relative positions of the planets in the solar system, the satellites orbiting the Earth and our place in the galaxy. Awesome with a smartboard as well." - by jbrown61 Solar Walk Ads+ enables you to: ► Observe the 3D model of our Solar system with all its objects in real time and in a proper orientation. Turn into an astronomer and explore planets, moons, satellites, asteroids, dwarf planets, comets, stars and other celestial bodies. Enjoy gorgeous graphics and visuals while navigating through the solar system. ► Make virtual flights from one space object to another. ► Travel in time and see what the universe and our Solar system looked like at a certain period. ► Find an exciting view of the Milky Way Galaxy. ► Watch a collection of educational solar system movies to learn about space-related topics including Earth's moon phases, Earth's cycles, tidal phenomena, and zodiacal constellations. ► Enjoy 3D planetarium with the help of special glasses and activating the anaglyph mode. ► Share interesting screenshots of the app with your friends. ► Choose the view mode comfortable for you (orrery/true-to-scale).

Read full descriptionHide full description
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 The nearest confirmed exoplanets stream in live from the NASA Exoplanet Archive, slotting into their true positions in the sky. 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 Complete English and Arabic support, with right-to-left layout. Switch languages anytime. Download Space and hold the universe in your hands.
