Cozmic Zoom

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!

Distance units

1 light-year (ly) = 9,460,730,472,580,800 meters
(distance travelled by light in vacuum in one year)

1 astronomical unit (au) = 149,597,870,700 meters
(approximate distance between the Sun and the Earth)

1 meter (m)
(originally defined as the ten-millionth part of the Earth's half meridian)

1 kilometer (km) = 103 m = 1000 m

1 millimeter (mm) = 10−3 m = 0.001 m

1 micrometer (µm) = 10−6 m

1 nanometer (nm) = 10−9 m

1 picometer (pm) = 10−12 m

1 femtometer (fm) = 10−15 m
