one of the major threads of the Wow! Signal is astrobiology. I've had David Grinspoon on to talk about the more promising places to search for ET life, and I recently had Geoff Marcy on to talk exoplanet habitability. Abel Mendez says eh'll be on soon, but I would to have some younger, less well known scientists on to talk about their astrobiology research.  It's not live, so we can record whenever it's mutually convenient. Just e-mail or comment here, and we can talk!

Hi Paul, This sounds like a lot of fun. I am based at Arizona State University and my research is primarily focused on what life is and how it originated. I have a background in theoretical physics so my approach to the problem is a bit different - I focus on mathematical and computational models for how chemical systems can complexify and I am particularly interested in how they process information. You can check out my group's website at Feel free to drop me a line if you'd like to chat! (either here through SAGANet, or at

Hi Paul,

This is interesting! I am based at NASA Ames in CA. My active research is about quantifying the concept of habitability by linking geology and biology computationally using energetics (geology being the "source" of energy, and biology being the "sink"). I'm also very interested in, and have done work on, Earth's ancient atmosphere and Mars' surface geology. There are a bunch of really keen, briliant and young scientists here: - cheers!

Yes, I am becoming more aware of Blue Marble since I joined Saganet. Your work sound really interesting - are there some papers or abstracts you can point me to?

Sure thing! Most of these papers have non-technical summaries too:

Hi Paul, this sound like a great opportunity! I am a research scientist with the Blue Marble Space Institute of Science and am based in Newark, Delaware (working out of my home office). My research focuses on planetary habitability, using one-dimensional and three-dimensional climate models to understand the astronomical conditions that contribute to a planet's ability to support life. I also study problems in environmental ethics, with a particular emphasis toward the ethics of space colonization, and I also like to think about SETI--mostly from a theoretical perspective. You can take a look at my published papers at and I can be reached by email at


I'll have a look at your papers. Maybe I could pair your interview with Abel's and do a whole episode on planetary habitability.

What are your best days/times for an interview?

Sure, that would be fun to do a combined interview with Abel!

My best days are Monday through Thursday, from 10:00 AM to 7:00 PM (Eastern). Feel free to send me an email ( with any details, etc. Thanks again!

Sounds great. Looking forward to it.

I'll bet that I have the *only* SETI station that actually still looks for the WOW.


What dates/times are good for you?

¿Are the Venusian sulphuric acid clouds the by product of long dead anoxogenic photosynthetic organisms?

Posted by Andrew Planet on May 4, 2020 at 2:51pm 2 Comments

I just read the piece at the link below entitled "Study: Life might survive, and thrive, in a hydrogen world."

I'd been thinking on similar lines recently, on different atmospheres with early life, but I was considering anoxogenic bacteria whose byproduct is sulfur instead of molecular oxygen. ¿Had life evolved on Venus could its sulfuric clouds be the signature byproduct of such life with no branches ever evolving to produce the equivalent of Earth's Great…


100 years tomorrow 26th April 2020 since we looked beyond the Milky Way Galaxy

Exactly 100 years ago tomorrow, the subject on whether this Universe is larger than the Milky Way Galaxy was brought up publicly at an event sponsored by the National Academy of Sciences, known as The Great Debate. Until then the Milky Way was thought to be this Universe.  Conference at the NAS
