We're investigating the heart on Pluto, this week on planetary radio.

I'm Sir Al Ahmed of the Planetary Society with more of the human adventure across our

solar system and beyond. It's been almost a decade since NASA's new horizon spacecraft

flew by Pluto and the data still yields results.

This week we're exploring the origins of Sputnik Planetia, the Western lobe of the

heart-shaped impact feature on Pluto.

It might be able to tell us whether or not the dwarf

planet actually has a subsurface ocean.

A Dean Denton from the University of Arizona will join us to talk about the work

she and her colleagues at the University of Bern and Switzerland have been doing

to understand oblique impacts, or as they call them, splats.

Then Bruce Betts, our chief scientist, joins me for a roundup of the most significant impacts in our solar

system in what's up. If you love planetary radio and want to stay informed about the

On July 14, 2015, NASA's New Horizon spacecraft flew by Pluto.

It was the first time we'd visited that world and its moons, and our first mission to

explore a body in the Kuiper belt. What we found there was

astonishing. Pluto is a complex world with varied geology and five moons, the

largest of which is Karen or Sharon, depending on on how you like to pronounce it.
