***READ THIS BEFORE ASKING ANYTHING***

This is the ultimate size comparison video that you can find on the internet in HD.
Starts with the tinyest dwarf planets of our solar system, then continues with large planets, dwarf stars, stars giant/supergiant/hypergiant stars, nebulae, globular clusters and galaxies.
There is the famous VY Canis Majoris rated as the biggest star known, but very few know that that the incredible IC 1101 is the largest known object in the entire universe. Only galaxy clusters are bigger than it.
Hope you enjoy this one.

FAQ:
-Sizes are not 100% accurate as there is no way to directly measure them.
-Star sizes may change in the future, and new stars may eventually appear into this biggest stars list

  • @tidby Maybe God made it possible so we can enjoy the starry sky.

  • But if God made the universe 6000 years ago...... how has the light from objects millions of light years away gotten to us yet?

  • @YamiPoyo This is a great question. We can see well into our own galaxy to understand what it looks like. However, the Galaxy pictures you see of the Milky Way are made up, to match our own observations. A real map of our own galaxy only shows about 50% of the entire galaxy which Hubble, Spitzer, Keplar, and Chandra all combined their images together to make. Knowing what our side of the galaxy looks like, we just duplicated it over to the other side into a 3D composite.

  • This is simply amazing. I wish I could live forever just to witness man developing enough technology to take us out of our own galaxy and maybe find other earth-like planets...

  • I want to see another creature of the universe in another Solar System

  • What if the largest galaxy (IC 1101), have civilizations on it that fight to colonize the entire galaxy? Even at warp-speed, it would still take them millions if not billions of years, to discovered everything in that galaxy alone.

  • How do they get a picture of our galaxy when were inside it?

  • nice music settling

  • Amazing
