Why we should search for alien artifacts in our own solar system.

There is a strong case to be made for searching for technological signatures of extraterrestrial intelligence. There is also a sound argument to be made for searching for such within our own solar…Continue

One of the theories for extraterrestrial intelligence is that it would most likely be postbiological societies where technology is more prevalent than biology. This would require von Neumann machines…Continue

The Role of "A.I." in the Search for Life

The search for alien life is an ongoing and continually time-consuming process. From analyzing the surface of planets/moons to detection of exoplanets, these processes can take weeks, months, or even…Continue

Hi all! I will past supplementary reading in our forum here, with papers I think are valuable related to topics we discuss in class, but which we don't have time to read (there are too many good ones!). For next week this is a great short paper on defining life if you are interested in digging deeper. DEFINING%20%20LIFE.pdf

Using tried and tested methods of constructing habitats from ethnobotanical and ethnozoological useful species for self sustainability on Mars

Posted by Andrew Planet on June 26, 2020 at 8:00am 0 Comments

To maximize crop yields on Mars it would be advantageous to do away with annuals and biannuals by engineering the latter into perennials as standard. Not only would that entail far less work to grow produce as the act of replanting is made obsolete, but per given cultivated area perennials bring forth more food and materials with less demand from the soil than the equivalent of annuals.

Imagine a superfood annual such as lentils engineered into a lentil tree for which there already…

This paper greatly extends the possibility of what a Goldilocks zone can be.  Its no longer the Goldilocks zone as a single expanse, its the Goldilocks zones for a particular area

¿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…
