What are some of the most shocking facts?
Wow, I didn't know that. Can you tell me some shocking facts about space?
Definitely. The universe is so vast that it contains more stars than there are grains of sand on Earth. Also, the light we see from stars sometimes takes thousands of years to reach us. And, there is a planet called HD 189733b, which rains glass at around 4,500 mph due to extreme winds.
