WHOA this talk is all about shooting incredibly fast projectiles at granite spheres and aluminum plates to learn about how debris flies off impacted asteroids. #DPS2023

(But now I have to hang out on Zoom and wait for panicked students to ask me questions during the online exam. SIGH.)

The density of Didymos has jumped up from 2.1 to 2.7 g/cm3 based on better shape modeling using both DART/Draco and LICACube/LUKE images. It's not nearly as much a rubble pile as assumed. #DPS2023

Haha! The #DPS2023 speaker just said that the biggest piece of the meter-sized NEO that hit the ground in Ontario a few months ago is likely in a vineyard. So, your best bet to finding it is to keep buying Ontario wine.

Neat statement about planet formation from #DPS2023: Around small stars, you don't expect large planets because you run out of gas in the disk quickly. And around big stars, so don't expect large planets because you run out of time (the stars destroy their disks before large planets can form)

The #DPS2023 prize talk right now is about an ongoing project to carefully image each of the giant planets with Hubble at least once a year and watch for changes. It's SUPER beautiful and interesting, and I'm reminded of this comic that summarizes how freaking cool Saturn is: https://www.smbc-comics.com/comic/2010-07-06
