About Me
Hello!
I am an Assistant Professor at Arizona State University in the School of Earth and Space Exploration and the Beyond Center for Fundamental Concepts in Science.
I am fascinated by all questions regarding the nature of life in the universe: How did life begin? How common is life? Are there universal laws of biological systems, as true here on Earth as they might be for extraterrestrial life should we ever find it? Its pretty exciting science, in part because there are currently more questions than answers!

¿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 0 Likes
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…

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 http://www.nasonline.org/about-nas/events/annual-meeting/nas157/

Sara,
Just wondering, I've been keeping an eye on www.spaceweather.com and the information being relayed there. And I noticed over the last few months every time the Sun Emits Solar Winds towards earth and the Site predicts the dates of arrival. On various locations around the world the weather turns severe on those dates. It appears to happen when Solar Winds are somewhere above 350 km/s. Now the Coronal Holes of the Sun seem to have enlarged quite a bit in the last year or two, causing these Solar Winds to emit more powerfully. They do not appear to be decreasing anytime soon. Any Astrobiologists seeing this correlation between the Sun, its changes, the Holes, the winds, and our planet too? ..
One last question, we have examined other Stars in the Universe go into Nova, and I'm sure the timelines of these events would appear to be random due to the immensity of the universe. And to see a Star Nova twice in a human lifetime would be most likely impossible. But has anyone at least tried?
My last question, I also noticed the span between Solar Min and Max is usually around 11-13 years .. But between the last one and the current one it was only about 5 years. I didn't see such a short gap between cycles at least in the last few decades. Are there any? ..
I have a question!
I am interested in studying astrobiology at phd in the United States!
I've been a Masters in Atomic Physics!
my thesis is about the effect of cold atmospheric pressure plasma on cancer cells!
Which university can I apply?
Thank you.
that's an honor to meet you:)

Awesomeness! It would be great to reach out to the wider astrobio community that way.

Hey Sara! I'm curious to know if you're the organizer for the ASU astrobiology activities on SAGANet. I'm considering trying to implement something similar for our Astrobiology Journal Club as well as a planned astrobiology lecture series here at CU in Boulder, so I'm looking for any advice on how to get that set up. Thanks for any help you can offer!
Thanks for opportunity, I enjoyed the discussion despite the technical problems we experienced.
Don't worry, when it comes to interdisciplinarity nobody knows where they are standing :)
