So Lisa, um, what do we- why do you think we need a shortlist? I mean, what do you- what, what changed in our field for, so you, you think that this kind of a research should be done?

So what's really, really interesting is that we're nearly at six...

Well, we just above 6,000 known worlds that circle around other stars, and among those are, as you said, 45, so more than, more than 40 planets that could potentially could be like ours.

And what we get from that is one out of five stars has a planet that could potentially be like ours, and that gets us to billions of possibility.

But where to look? This is what this paper is about.

So Abby and Gilles and Lucas, the team that wrote this paper, identified these amazing planets that are within the limits of the habitable zone and small enough to be rocks like ours.

But for me, an extra excitement are these planets on the edge because a planet on the edge teaches you where habitability ends.

And I think that that will be really great, and it's something that I think everyone's really looking forward to for the future.

Enjoy.

We live in an incredible time of exploration on the verge of finding out whether we're alone in the cosmos or not.

This is one of the biggest question humankind has ever asked, and now, for the first time, we have a tool that could find out because the James Webb Space Telescope is a telescope large enough to be able to catch light from planets like ours, as small as ours, but circling other stars light-years away.

Because this search is a search over vast cosmic distances, even light needs years to travel these trillions of miles between stars.

So when you look up at the sky at night, you look back in time.

Let's imagine you were on a planet circling our neighboring star about four light-years away, then you would see the Earth tonight like it was four years ago.

On a planet 17 million light-years away, you could still see the dinosaurs roam here, and it also means that out in the sky, there is a star whose light arrives tonight that was sent out when you were born, your personal connection to the cosmos.
