Episode 54: Dusting off the Disks
We recorded this episode a few months ago and are dusting it off today. We’re leaving a bit of dust though, because that’s what makes debris disks so exciting! Malena tells us about a disk that is both beautiful in appearance and in its scientific potential to reveal planetary dynamics. Alex tells us about a disk that might have as much water as the solar system, but unfortunately none of it is liquid (or confirmed). Will brings us a space sound that makes the episode a little more trashy.
