UC Berkeley SETI researcher Andrew Siemion and his colleagues have put an upper limit on the number of civilizations in our galaxy that are capable of giving us a call.  He’ll explain their reasoning and provide other search updates. Emily Lakdawalla is never at a loss for great space images.  This time they include watching our moon transit the Earth, and a surprisingly beautiful scoopful of Martian dirt. Bruce Betts would rather not talk about the bad, bad things that can happen at high altitude, but he’s happy to tell us about the night sky and provide a Random Space Fact.  Bill Nye returns next week.

I am so pysched we could be on the brink of discovering life/water in other star systsems, however, my recent thought is, if we do find life and if we stand behind evolution, would there have to be a catastrophy during the jurassic age of that planet's time line? What happened if dinosaurs did not become extinct and were a predator to the point they interfered with humans evolving?

Emily Lakdawalla: 03/11/2013 06:57 CDT

Dylan, I suggest you check out Harry Harrison's alternate history fantasy series that begins with "West of Eden" for one author's imagining of an answer to your questions!

Dylan Maulucci: 03/19/2013 08:41 CDT

Thanks Emily. I will look out for that series. I am reading Sagan's Cosmic Connection right now and the chapter Chauvinism also approaches the evolution here as well its effect elsewhere. I love Sagan!
