There's a lot to wonder about space. The fact is we don't know all the answers about it. We know it's vast and beautiful, but we're not really sure how vast (or how beautiful, for that matter).

Space is mysterious and beautiful, understand it more with this list of interesting and mind blowing facts about space, planets, moons and stars!

I found many of these on Pinterest, so thought to share it with you all.

1. You are actually gazing down, when you look up in the sky

Instead of looking up into the sky, you are actually gazing down into the infinite cosmic abyss, with only gravity holding you to the surface of the earth.

2. You age the same as the Universe

You are the same age as the universe, it is because matter can never be created or destroyed.


3. Space

There exist an area so unfathomably large that humans refer to it simply as "space".

4. Speed of light and your shadow

Your shadow is a confirmation that light has travelled nearly 93 million miles unobstructed, only to be deprived of reaching the ground in the final few feet by you.

5. There's only one sunset

There's only one sunset and it has been going around the earth for billions of years.

6. Space battles

Considering how big the universe is, there are probably space battles going on somewhere right now.

7. Eight Planets

If someone 50 years ago were told that there would one day only be eight planets, they would think something incredibly excited happened.


8. Birth on Mars

When the first child is born on Mars, we will have to add planet of birth to our passports.


9. Shooting Sci-Fi films in actual outer space

Eventually the human race will develop to a point when we shoot science-fiction films in actual outer space.

10. Footsteps on sand

It takes a whole ocean and the moon to erase your mere footsteps on the sand.

11. Youngest in the universe

At one point you were the youngest being in the entire universe, and at another point you will be the next being to die.

12. Name of our Galaxy

We have named our entire galaxy after the secretions of a cow's udders.

Milky Way Galaxy

13. Moon was invaded

Aliens invaded the moon on july 20th, 1969.


14. We eat sunshine

Everything we eat is processed sunshine.

15. Digging up dirt

Whenever you dig up dirt or a rock, that could be the first time it has seen sunlight in millions of years.

16. 65 Million light years away

If people on some planet,65 million light years away look at earth, they see Dinosaurs.

17. Andromeda galaxy thinking about Milkyway galaxy

There might be people in Andromeda galaxy who are thinking about whether or not there are people in the Milky Way galaxy thinking about them.

18. Sun set & sun rise are the same

If you are watching a sunset , someone on the other side of the earth is watching the same sun rise.

19. You have never been in the same physical place twice

You have never been in the same physical place twice since the earth, solar system, and galaxy are all moving through space.

20. Not first

We might not be the first species to get this far.

21. Night sky is not the single moment

Not all starlight is the same age, some of it is millions or even billions of years apart, even though it hits your eye at the same time. So the night sky is not the single moment in the universe but rather a patchwork of time billions of years in breadth.

Some more interesting facts!

  1. A light year is the distance covered by light in a single year, this is equivalent to 5.88 trillion miles (9.5 trillion KM).
  2. The width of the Milky Way is around 100,000 light years.
  3. Pluto is smaller than the Earth’s moon.
  4. There are giant pools of water floating in space. These have 140 trillion times the amount of water found on Earth.
  5. The hottest planet in our solar system is Venus. Most people often think that it would be Mercury, as it’s the closest planet to the sun. This is because Venus has a lot of gasses in its atmosphere, which causes the “Greenhouse Effect”.
  6. SPACE IS COMPLETELY SILENT. There is no atmosphere in space, which means that sound has no medium or way to travel to be heard. Astronauts use radios to stay in communication why in space, since radio waves can still be sent and received.
  7. If a star passes too close to a black hole, it can be torn apart.
  8. Venus is the only planet that spins backwards relative to the other planets.
  9. The highest mountain known to man is the Olympus Mons, which is located on Mars. It’s peak is 15 miles (25KM) high, making it nearly 3 times higher than Mt Everest.
  11. The Milky Way galaxy is whirling rapidly, spinning our sun and all its other stars at around 100 million km per hour.
  12. NASA’s Crater Observation and Sensing Satellite (LCROSS) declared that they have found evidence of significant amounts of water on the Earth’s Moon.
  13. The Universe may have neither a centre nor an edge, because according to Einstein’s theory of relativity, gravity bends all of space time around into an endless curve.
  14. The opposite of black holes are estimated to be white holes which spray out matter and light like fountains.
  15. In space the skin on your feet peels off!. This is a pretty gross fact but in the micro-gravity environment, astronauts are not using their feet to walk. Therefore the skin on their feet starts to soften and flakes off. As laundry facilities do not exist in space, astronauts will wear the same underwear and socks for a few days. Those socks then need to be taken off very gently. If not those dead skin cells will float around in the weightless environment.
  16. You become taller in Space. Another change to the human body in micro-gravity is that spine straightens out, as gravity is not pushing you down. In fact you can be up to as much as 5cm taller in the Space Station.
  17. Space is not that far away. Space officially begins at the universal marker of the Karman Line. This invisible boundary is 100 km above the Earth. In theory if you could drive your car upwards, you could be in space in less than hour.
  18. The full cost of a spacesuit is about $11 million although 70% of this is for the backpack and the control module.

Additional Information

There are thousands of other planets out there.
We have eight planets in our Solar System. However, outside of our Solar System there are thousands of other planets. The extrasolar planets are in orbit around another star. So far we have almost 1800 confirmed new worlds, with another 3000 awaiting confirmation. Astronomers are looking to a star’s goldilocks zone for planets that may be habitable, just like the Earth. The majority of planets discovered so far are hot gas giant planets.

The astronauts were placed in quarantine after returning from the moon.

There is a famous image of President Nixon talking to the Apollo 11 crew consisting of Michael Collins, Neil Armstrong and Buzz Aldrin. This continued until after the Apollo 14 crew returned safely. After this it was decided that the Moon did not contain any deadly diseases. The Apollo 13 crew, who had a malfunction and had to return to Earth, did not have to be quarantined after their re-entry as they didn’t actually walk on the moon.
