Mythologium | ISMythology

I’ll be speaking about the mythologies of alien life, but there will be a whole bunch of talks and discussion in realms of mythology, folklore, literature, psychology, and more!

Feedback on Astrobiology Workforce Development Tools, Resources, and Opportunities The purpose of this form is to assess how well important tools, resources, and opportunities for career development are advertised in and used amongst the astrobiology community. Feedback shared here…

The NASA DARES Task Force 2 is seeking input from those currently pursuing careers in astrobiology regarding the question: "What tools, resources, and opportunities have impacted your astrobiology career so far?"

Astrobiology 101: Why is Water the Solvent of Life? Part 1 of the chemistry that makes water crucial for life as we know it

In this new several part series of Astrobiology 101, we’ll explore why water is the solvent for life as we know it and whether other solvents might be possible for alien life.

The origin of life wasn't fat-free James SΓ‘enz studies how fatty molecules might have helped life get started

Lipids are kind of the ignored middle children of origins of life research. It's time they got a bit of attention, too!

This week's post is a Q&A with geoscientist-turned-??? (interdisciplinary folks know the struggle) @jamessaenz.bsky.social about why there's no cutting the fat from origins. πŸ§ͺ

That "Two Times e to the Two-i-pi" Thing from Project Hail Mary, Explained A romp through number theory, geometry and trigonometry, the unit circle, Euler's formula, complex numbers, and more to find the cube roots of eight

A little explainer for those who might wonder why the main character says that "two times e to the two-i-pi" is the answer to the cube root of eight in the first chapter of Project Hail Mary.

February Book Club: Project Hail Mary Our 2026 Astrobiology and Panzoic Book Club now changes gears a bit with a reading of Andy Weir's tale of adventure to save humanity with the help of a friend far, far away from home

Our book club will be reading Project Hail Mary this month!

I'm so excited to read it again, and do some deep dives on the science and ideas that Andy Weir brought to the pages.

Really hoping the film coming out soon does justice to the book.

Could We All Be Aliens to This World We Know? On the origins of life beyond Earth and the hypothesis of panspermia

Jessica Xhumari, one of my Visiting Schooars at BMSIS, recently helped the folks at Melody Sheep with some research on a new video (linked in the post), and it seemed like a good time for talking a bit about the potential for life to travel between worlds.

Snow isn't actually white Winter wonderlands are only possible thanks to a sparkly light trick.

Cold temperatures and severe winter weather are on the way for much of the U.S. this weekend. Seems like a good time to review a little of the science on why snow appears white ❄️

I’d post a lot more here if it weren’t for the stupid character limit. Some of us actually enjoy writing and reading more than just hot takes and mini bits of information. I never liked reading threads of posts on Twitter and don’t like it here either.

Now I feel ever more that I need to write a short essay on what it was like to visit the Ancient Aliens theme park in Switzerland, which honestly was more of a shrine for Erich von DΓ€niken to celebrate his own life more than anything.

Amidst all of hte choas and uncertainty, we can still experience the profound and beautiful.

In my most recent piece on The Cosmobiologist, I argue that everyone should, if possible, try to experience a total solar eclipse in their lifetime.
