A Single Light

Description

Many problems remain in finding and/or communicating withintelligent life beyond Earth. What language should we use? How different would their civilization be? Do we need to find Dyson Spheres around a star to guarantee intelligent life on nearby exoplanets? What if we don’t ever find evidence of intelligent life? Is it worth the hunt, or will the alien blind boxprobably be empty and thus pointless? In this session, we will explore these big questions.

Description

Exoplanets are fascinating, but how do we discover them—and could any harbor life? Only time will tell, but as technology advances, our chances of finding answers improve. Even if we never detect life, exoplanets are still worth exploring. Let’s find out why!

Mars is named for the God of War, and many battles have been fought over whether the red planet has life. From the 1700s to today, scientists have hunted for life, though in very different ways. Will we ever find life on Mars? Should humans do science there themselves? Let’s find some answers.

Description

To understand the potential for life in the solar system, weneed to learn about the planets. We start at the Sun (not a planet, but some believe it could have life) and hopscotch through each of the eight planets. We don't find life, but we learn what makes each planet unique and what keeps it lifeless. With this knowledge, we can better assess which exoplanets may or may not have life.

Today we take a trip to the beginning of the solar system to learn a couple of theories about the beginning of life.

There are possibly billions of exoplanets in our galaxy, butmost of them will not have any life on them because they are outside of their star’s habitable zone. What is a habitable zone? Why is it so important? Can a planet or moon outside of the habitable zone harbor life? We explore these questions in today’s session.
