But these monsters sitting inside galaxies might also be the architects of them, moving gas around and helping to decide what new stars, what new planets actually get built.

Let's talk about that here with Sarah Rugheimer, an astrophysicist at the University of Edinburgh.

Sarah, welcome back to the show.

Thanks for having me.

New simulations show how a white dwarf star can steal material from its neighbor until it transforms into something even more extreme.

What does this all mean? Let's talk about it here with astrophysicist, astrobiologist, and all around good person, Sarah Rukeimer, who's a professor at the University of Edinburgh.

Sarah, welcome to the show.

Thanks for having me.

I'm Lisa Wexler filling in.

Joining us now is Dr. Sarah Rugheimer, the astrobiology professor at the University of Edinburgh in Scotland, where I've been, by the way, not to attend, but I've seen it, it's extraordinary.

And Dr. Rugheimer is gonna talk with us about something near and dear to my heart, which is light pollution, its impact on the dark skies or the lack thereof, its impact on wildlife, and from the point of view of an astronomer, what she sees are so damaging about light pollution and how do we begin to think about it and address this very, very, very big, I think worldwide concern of creeping light on our night skies.

Hello, Dr. Ruckheimer.
