If you’re a pilot, you love to hear that the weather is “clear and a million.” That’s good visibility!
But tonight as the Sun set, it wasn’t just clear and a million. It was clear and 832,517,397 kilometers, all the way to Jupiter. (The bright spot visible at the top left.)
It was also 219,199,744 km to Venus, the bright spot in the lower center.
Not bad for your standard Mark I eyeball! Of course, 30 minutes after this it was dark enough to start seeing the stars, which are much farther away. And if we had dark skies (I’m in LA – we don’t) we could see the Andromeda Galaxy…
It’s a big Universe. Go take a look!
