Let me introduce a few of them.
There are no bridges across the Amazon River.
Amazingly, the inventor of the Rubik's Cube reportedly took a full month to solve it after building it. Incidentally, the current world record is under 5 seconds.
The sunset on Mars, a red planet, is blue. The sunset on Earth, a blue planet, is red.

The tallest and largest volcano in the solar system is located in the desert of Mars, Earth's neighboring planet. This shield volcano is called "Olympus Mons" and stands 16 miles (24 kilometers) tall. That means it's about three times the height of Mount Everest.
It is estimated that there are approximately 500 million planets in our galaxy that are capable of supporting life, like Earth.
