Description
Humanity gets a bit of payback on asteroids for the rude destruction of the dinosaurs and almost all life on Earth 65 million years ago with the DART spacecraft’s successful impact on a teensy-weensy asteroid. New research suggests the asteroids teamed up on Earth long ago, and that there were at least two major impacts to end the Cretaceous and the dinosaurs. Hot and barren Mercury may have significant deposits of solid ice at its poles, and we learn about photon rings around black holes. No giggling.

Vorticity
Livening up your day from the swirls in your morning cup of coffee, to the whirlwinds of tornadoes, and the devastation of hurricanes, vorticity lets you put a new spin on life. Vorticity is adaptable to your needs. Taken from the curl of your flow velocity, vorticity can give you that spinning feeling even with linear motion in a sheer layer, or vanish in an irrotational vortex. Listeners of this episode of Walkabout the Galaxy can get a free vortex generator, just mention "astroquarks" when you order. So don't just blow smoke, study a smoke ring with vorticity. Vorticity, designed to delight (Whirlpool).
