...I kid. Here’s the distance, to scale, between the Earth and the moon. Doesn’t look too far, does it? Inside that distance you can fit every planet in our solar system, nice and neatly. That little green smudge is North America on Jupiter. This right here is a comet. We just landed a probe on one of those bad boys. Here’s what one looks like compared with Los Angeles. But that’s nothing compared to our sun. Just remember. There are more stars in space than there are grains of sand on every beach on Earth. Which means that there are ones much, much bigger than little wimpy sun. Just look at how tiny and insignificant our sun is. But even our galaxy is a little runt compared with some others. Here’s the Milky Way compared to IC 1011, 350 million light years away from Earth. In JUST this picture taken by the Hubble telescope, there are thousands and thousands of galaxies, each containing millions of stars, each with their own planets. And just keep this in mind — that’s a picture of a very small, small part of the universe. It’s just an insignificant fraction of the night sky. Here’s one of the galaxies pictured, UDF 423. This galaxy is 10 BILLION light years away. When you look at this picture, you are looking billions of years into the past.
