1. This is the Earth – where every single human has ever lived.
2. And this is our local neighborhood, the solar system.
3. Here’s the distance, to scale, between the Earth and the moon. It looks far, but is it?
4. Nope. You can just about fit every planet in our solar system within that distance.
5. But some of these planets are very large indeed. That green speck you see? That’s what North America would look like on Jupiter.
6. And here’s how the Earth fares next to Saturn. Not very big at all, right?
7. Here’s a fun fact: if Earth had Saturn’s rings, the view from our soil would look like this:
8. And to make things even more interesting, here’s what a comet would look like on top of Los Angeles:
9. But that’s still nothing considering how small we are compared to our sun:
10. To drive that point home, here’s another comparison:
11. Here what our planet looks like from the moon:
12. From Mars:
13. And from behind Saturn’s rings:
14. This is the earth beyond Neptune, 4 billion miles away. To paraphrase Carl Sagan, “Everyone and everything you have ever known exists on that little speck”.
15. Carl Sagan once once famously said that there are more stars in space than there are grains of sand on every beach on Earth:
16. Which means that there are ones much, much bigger than what would be our relatively tiny sun. I mean, just look at it:
17. But even that was nothing. The biggest star, VY Canis Majoris, is 1,000,000,000 times bigger than our sun:
18. But none of those come anywhere close to the size of a galaxy. If you reduced the size of our sun to that of a white blood cell, and then reduced the size of the Milky Way galaxy using the same scale, the Milky Way would be the size of the United States:
19. But even our unimaginably massive galaxy is TINY compared with some other much larger galaxies. Here’s the Milky Way compared to IC 1011, 350 million light years away from Earth:
20. But it gets even better. This picture taken by the Hubble telescope reveals that there are THOUSANDS of galaxies, each containing MILLIONS of stars, each with their own planets.
21. This is UDF 423, a galaxy which is 10 BILLION light years away. That means this image, even when viewed in a telescope ‘now’, right here on earth, is actually 10 billion light years old. Try to wrap your head around that one.
22. But you should also know that all of this is just a fraction of the universe.
So to put this all in perspective, let’s look at earth, and then start to zoom out…
Our Solar system…
I am prepared…
Oh boy…
Arghh…
*starts getting dizzy*…
*almost fainting*…
Woah. There it is. The entire observable universe as we know it.
Mind = Blown.
