and good luck. Tonight, a bit of father-son dialogue from the archives:

Son: What's that star, dad?

Father: That's Betelgeuse.

Son: How far is it from here?

Father: It's really far, son—six hundred light years.

Son: Wow!

Father: That means the light we're seeing now was made in the star a long time ago.

Son: When will we see the light it's making now?

Father: (Chuckles) No, son. You and everyone you'll ever know and care about will be long dead before that light makes it here.

Son: Oh.
