100 AUs

A fascinating story from the world of science. The first Voyager probe sped past the 100 AU mark this past Wednesday.

What's an AU?

AU stands for Astronomical Unit, a unit of length equal to the distance between the Earth and the Sun, or about 93 million miles. Isn't that cool? Something that we mere mortals crafted is now flying past the astronomical 9.3 billion mile marker.

Good thing it's not on a toll road.
