Episode 34: Ladder to the Stars with Mookie Terracciano

Posted Jun 24, 2013 by bn

Billie Holliday asks a Lot of non-rhetorical questions:

Of these, this episode of the titanium physicists podcast shall answer one.

You can use a “ladder” to determine the distance to a star. and then you GRAB IT!

Specifically the last one.  (the answers to the other questions are: “it depends.” “pretty high” and “what time is it?”)

The answer to this one is also “it depends”, but even then, it’s not like we have  a really long measuring tape to answer the question. No, the distance to astronomical objects is determined through a lot of cleverness. Today we’ll be talking about the Cosmological Distance Ladder.

I have invited Michael Mookie Terracciano back onto the show, because he has a new webcomic out called STAR POWER. It is lots of fun.

To help me explain the Cosmic Distance Ladder, I’ve invited two astronomers on: the AstroPixie, Amanda Bauer, and my old astronomer buddy James Silvester (who hosts his own astronomy podcast: Astrarium).
