Seth Shostak’s Confessions of an Alien Hunter

June 23rd, 2009

No, Seth Shostak is not a Predator, although that would be a cool book…

Seth is a radio astronomer who works for the SETI Institute hunting for alien signals from space, and he has a book out called Confessions of an Alien Hunter which is about SETI and his personal experiences with the project.

You may have noticed me linking to some of Seth’s articles in the past, sometimes responding at length or just a brief mention in Starlinks.

First let me say a few positive things about the book.   Notably, it’s quite well written and an engaging read.   I tend to find non-fiction slow going sometimes, and sometimes get mired in something I want to finish but begin to dread.   Confessions of an Alien Hunter is chatty and entertaining throughout.   I liked the dramatized scenes of what happens when there is a possible detection, and the combination of over and under reaction by different groups (e.g., the scientists and the media).

After a read of the book, you’ll have a pretty fair view of the history of SETI without a lot of excessive gushing (acknowledging that Seth is an optimist).   I was particularly interested in the description of events concerning how the federal government shut down NASA funding for SETI and how the effort transitioned to private sources of support.

I was also favorably impressed by how well the point was made about how poor the SETI search has been to date.   I think there’s a general notion that if aliens are trying to contact us, we’ll know it immediately and easy, like in a Hollywood movie.   It would be even tougher if not impossible with current technology if they’re not trying especially to talk to us.   I also think there’s an excellent point to be made about how the quick pace of technological advancement has meant rapid growth in SETI power.   Radio astronomy in particular benefits from computer advances more dramatically than most other types (e.g. optical).

There’s a good update on exoplanet discoveries (although that’s rapidly getting outdated as the field is moving so fast) and how one term in the Drake Equation is getting nailed down a lot better in favor of optimistic numbers.

Personally, I think SETI is a longshot to turn up something in our lifetimes, but definitely worth the effort at least at levels currently planned.   I am not optimistic enough to shift own my research to SETI, but I would if we found a signal.   And that’s another detail I appreciated learning.   The way the searches are done, there’s not much information being collected initially and it might take years to build the equipment to properly followup the detection of a real SETI signal, if it comes in at a weak level (which wouldn’t be unlikely).

Seth also covers the claims by UFO fans and abductees in a pretty reasonable way, in my opinion.   He’s fair, and very skeptical, which I think is the correct response given the available evidence.

The book is not very technical in general, and if you’re interested in the nuts and bolts of SETI and how different searches have been conducted in detail, you need to look elsewhere.

Finally, here’s a promotional youtube video featuring Seth talking about SETI:

Wish I had such nice videos to promote my books. Well, Seth deserves it. Good book.

Let me know if you’re interested in an interview with Seth and feel free to suggest questions.   I know him online a little bit and expect he’d be happy to do it.
