Every weekend when I can I do an interactive live video chat on Google+ where people can ask me questions about space and astronomy. I call it Q&BA, and it's always fun to hear what questions are on people's minds.
Apropos of my recent post about Saturn's moon Enceladus, I got this question: "Which moon has the best chance for life: Titan, Europa, or Enceladus?" This is a common question, and worth exploring! Here's what I said:
Mars is still an interesting place to look for life, but those moons -- all three -- are very, very enticing. I'd love to see us launching future space probes with some icy targets in their sights.
[P.S. The aspect ratio of the video is stretchy for some reason; the video looked fine before I uploaded it to YouTube. I'll try to track this problem down.]
I have an archive of Q&BA links and videos. Take a look and see if there are other ones that tickle your imagination.
- Q&BA: Can we build a space habitat?
- Q&BA: The Science of Science Fiction
- Q&BA: How does a gravity slingshot work?
- Q&BA: Why spend money on NASA?
- Q&BA: What happens if you are exposed to the vacuum of space?
