This is Scientific Americans' 60-second science. I'm Steve Merski.

Astronomers have cataloged more than 3,500 exoplanets since the first one was found in 1988.

Part of the revelation and the revolution that's going on is that actually planets are incredibly abundant,

and that means that potential incubators for

life are everywhere in the universe.

Columbia University astronomer and Scientific American blogger Caleb Scharf.

He was part of a conversation about life in the universe at NYU on March 22nd, at which he was asked what our new understanding

of the abundance of exoplanets out there does to the odds of finding life.

What it definitely does is increase the odds of us finding an answer, I think.

I think that we can say with some confidence because we didn't know that there were so many

planets around other stars 20 years ago. And that also means that many of them are pretty nearby

to us. So what it definitely alters is the odds of us getting some answers. Because suppose planets were actually very rare.

The solar system was sitting here and then you had to go a thousand light years to the next planetary system.

That would be difficult for us if we wanted to study those planets because they're a long way away.

So, you know, I'm doing the politician thing of kind of circling around the question here.

So it definitely, the abundance of planets improves the odds of us obtaining an answer, which is huge.

Don't underestimate that.
