Numbers that explain the economy. We love them at the indicator from planet money and on Fridays we discuss indicators in the news like job number spending the cost of food sometimes all three.

afford your eggs. I'll be here all week. Wrap up your week and listen to the

indicator podcast from NPR. You're listening to Shortwave from NPR. Hey

civilizations even at that point have a record of exploding stars that's Serafina El Badry Nance.

She's an astrophysicist and an expert in supernovas,

And she studies one star in particular,

Beetlejuice.

It's the upper left shoulder of Orion.
