NOT Your Grandma's Solar System● A new perspective on prospects
for life elsewhere
– Life is more tolerant of extreme environments than previously thought.
– DNA analysis suggests life likely originated in volcanic vents.
– Life's prerequisites (especially liquid water) are more prevalent in solar systems.
– Planets share material. Impacts can transport life naturally from one world to another increasing the odds of survival.
