Astrobiology and the Search for Life

~60 min · 15 stations

Astrobiology and the Search for Life is a self-paced learning path in Astronomy & Space Exploration, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify biological markers for alien life; trace the evolution of planetary science; categorize stars based on habitability potential.

Conductor

The Conductor

All aboard the cosmic express! We are charting a course through the stars to find signs of life. Mind the gap between science and speculation as we depart.
