Documentaries - Size of the Universe - Documentary 2017

To try imagining how big, place a penny down in front of you. If our sun were the size of that penny, the nearest star, Alpha Centauri, would be 350 miles away. Depending on where you live, that’s very likely in the next state (or possibly country) over.

Attempting to imagine distances larger than this quickly becomes troublesome. At this scale, the Milky Way galaxy would be 7.5 million miles across, or more than 30 times the distance between the Earth and the moon. As you can see, these are rather inhuman dimensions that are almost impossible to really get a sense of.

But that doesn’t mean it’s completely impossible. Astronomers have made observations and simulations that in some way capture the enormity of our cosmos. In this gallery, Wired will look at the size and scale of the universe’s largest, farthest, and most mysterious objects.
