Yeah, a lot of times, looking up in the sky, it's very hard to distinguish satellites and things from, in fact, we had that problem when we filmed the tear in the sky in Catalina.

The first white object that's seen, the first bright light that the Catalina group saw that we tracked turned out to be the space station.

So, yeah, it's hard to do.

It's easy to make a mistake.

It turned out to be very useful.

When we wrote up our scientific paper, it was very useful because it showed that we're performing due diligence.

We're actually researching and actually studying, actually trying all the hypotheses to see what it could be.

And we found that the...

that that was actually the space station.

Actually, Matthew did that part of the analysis.

It was his hypothesis that it was the space station.

And he really tracked that down.

He did a fantastic job.

He actually used the pixel size on the camera, on the iPhone camera, used the number of pixels that the light took up.

And knowing the distance to the space station, he used the pixel size to estimate how big the space station would be.

And he was off by one foot.

He basically measured the size of the space station from an iPhone camera picture is what he did, which was brilliant physics work.

It's very nice.

And that's really true.

And that's why a lot of the work that we've been doing has been to...
