The whole universe in your hand!
Cozmic Zoom is a fascinating insight into the universe, between the infinitely large and the infinitely small.
Based on accurate scientific data from the best sources, Cozmic Zoom will take you on a journey through the world of particles and atoms, the cells of the human body, the planet Earth and the Solar System, the stars and the Milky Way, the distant galaxies, up to the edges of the known universe, with a simple swipe of the finger.
While enjoying the trip, you will also improve your knowledge about astronomy, biology, cosmology, physics, space, and much more.
“Exploration is in our nature. We began as wanderers, and we
are wanderers still. We have lingered long enough on the shores of
the cosmic ocean. We are ready at last to set sail for the stars.”
― Carl Sagan
Come on, let's sail to the stars... To infinity... and beyond!
Cozmic Zoom is an overview of the whole universe, between the infinitely large and the infinitely small. All the proportions are respected, although sometimes the orientations and colors may have been adjusted for esthetic reasons.
Zoom with these different gestures: swipe, fling, pinch (if your device supports multitouch).
