I'm John Batchel with David Livingston, my colleague and co-host. This is Hotel

Mars. And we've not only discovered

an explanation for a runaway black hole, but one that's coming at us. Now, the question is,

what else is out there? Professor, this is Peter Van Dukkham, and the astronomy department at Yale

University. We give you an unlimited budget and ask you what do you want to do next,

given the time on these telescopes is dear.

Yeah, that's always a...

I don't think there's a single astronomer who does not have an answer to that particular question.

We always want more data, better data, you know, etc.

You know, I could give answers like a large X-ray telescope

because then we might be able to see the black hole itself,

like emission from the location of the black hole.

We think we see hints of that, but we're not sure.

That would be very interesting.

You know, anything larger is, of course, the standard answer of any astronomer.

But I'll give two kinds of answers.

The first is the telescope that I would build to find more of these things is being built as it happens.

It's the Roman Space Telescope and that will join the Euclid Space Telescope that was

launched, I think, a year ago, a year and a half ago.

And Roman is next.

That's the American contribution in this particular field.

And that will image very large regions of the sky with the resolution
