Space is ✨groovy✨

-There are more stars in the universe than grains of sand on all the beaches on Earth. That’s at least a billion trillion!
-The universe is observed to be 13.8 billion years old and has been expanding since its formation in the Big Bang.
- If you piled up all the visible universe it would account for only 5% of the total mass. At least 27% more consists of invisible “dark matter”
- Whenever we observe a distant planet, star or galaxy, we are seeing it as it was hours, centuries or even millennia ago.
