● A fairly broad and extensive knowledge of the planets and moons in the solar system and how a perspective on all of these objects leads to appreciation for the prospects of life elsewhere in the Solar System and in the Galaxy.

● An ability to keep current – on your own – with events going on in the night sky, long after this course has ended. “Keep looking up....”

● An ability to track the progress of and results from the vast investment in space exploration that we make as a society and appreciate why these investments are more important than just pretty pictures.

NOT Your Grandma's Solar SystemA Brief Warning

● Yes, this course is a 1000-level “introductory” course, however...

– The “1000” is an indicator that the course has no prerequisites, not that it is “easy”

– The information content is dense

– Astronomy is simply applied physics – be prepared for some math and conceptual physics.

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.

The techniques applied to date find “big” planets, but today we are finding earth-sized planets and developing the technology to determine if they are earth-like.
