## What is COSMOS?

Explore the universe from the palm of your hand.
COSMOS is a space exploration app that takes you on an 
immersive journey through the solar system, distant galaxies, 
black holes, asteroid belts, and dwarf planets - all with 
stunning visuals and real astronomical data.

EXPLORE 5 COSMIC REGIONS

Milky Way - FREE
Start your journey in our home solar system. Visit all 8 
planets, 13 moons, and the Sun. Tap any world to discover 
facts, stunning imagery, and take a quiz to test your knowledge.

Andromeda
Travel 2.5 million light years to our nearest spiral galaxy. 
Explore 5 deep-space objects including satellite galaxies M32

Black Holes
Confront the most extreme objects in the universe. From 
Sagittarius A* at the heart of our galaxy to M87* - the first 
black hole ever photographed.

Journey through the asteroid belt between Mars and Jupiter. 
Meet Vesta, Bennu, Ryugu, Psyche and other rocky relics from 
the early Solar System.

Dwarf Planets

fascinating to ignore.
