This is the audio-only version of Q & BA Episode 4: The Gravity of the Situation.

Ah, the feel of someone in your arms. You're so close, you can swear you feel their gravity drawing the two of you together... or could it be from something else?

Plus, I screwed up last week, and I admit it.

This is the audio only version of Q and BA Episode 3: The Farthest Star.

Episode 2 of Q and BA answers the question, "How dense is the center of the Sun?" Turns out it's pretty frakkin' dense. After that, I go on a bit of a free-style discussion of how the Sun makes energy, and just how much it makes (hint: a LOT). Oh yeah-- there are marshmallows, too.

Q and BA Episode 2: Galaxies

The very first episode of Q and BA deals with galaxies, those pretty and pretty weird island universes of gas, dust, and billions of stars. What shapes do they come in? What kind do we live in? Can you see 'em your very own self? All this and more is answered by me, Phil Plait, an astronomer and budding video star.

Introducing "Q&BA", the new feature of the Bad Astronomy Blog! Every week, I'll make a new videoblog answering reader questions about astronomy. The first vid goes up on Monday, February 5, 2007. If you have a question for me, send it to thebadastronomer "at" gmail "dot" com or post it on the Bad Astronomy and Universe Today forum.
