This is CBS. I on the world. I'm John Batchler.

Bob Zimmerman, he's here with Behind the Black, and we're going immediately to check in on solar activity.

Bob, any change of direction? We were talking maximum.

Yes, we're still in the maximum, but, you know, the sun last month crashed in terms of activity after going super high the previous few months, totally outside the predictions.

Totally.

The predictions have all been wrong.

And so this last month, I do this every month, and this last month, the activity rose again after the crash of last month.

But it didn't rise to the level it was before the

previous two months ago, but it did rise to the level it had during the summer. And in all

cases, this is way above the predictions. Bottom line is it just proves once again, we have

no idea what the son's going to do. We don't understand these processes. And this, of course,

is a fundamental factor in studying the climate, since We don't understand these processes. And this, of course, is a fundamental

factor in studying the climate. Since we don't understand the sun, we cannot say anything

in climate research is settled. We don't know anything about what the climate will do because

we do not know what the sun is going to do. And the sun keeps proving this month to month, John.

We go to the surface of Mars. This is really cool.

His name is Peter Bueller.

He's at the Planetary Science Institute Research,

and he's looking at the problem of,

was there ever liquid water on the surface of Mars?

Explain, Bob.

All right, so the basic problem, Mars, is that we see a lot of geological features on the planet that suggest water flowed at some point on the surface.
