I cannot say enough about this wonderful class. I am a senior in high school and have never taken a class on astronomy or anything of the sort, so I was quite nervous heading into this course. Professor Spergel explains things so clearly and all the presentations were executed very well! This class is a perfect course for those wanting to learn more about our universe, it is not unbelievably difficult but still challenging enough to work your brain and expand your knowledge. I love this class! Thank you Professor Spergel, I will never forget this course.

In this course unlike routine things like Big bang,Solar system,Galaxies and so on,I learnt new things such as Habitable zone and Goldilocks,Exoplanet zoo,Concept of light,Evolution,Quantum mechanics,synthesizing of life and Fermi paradox. The interviews of eminent scientists are very very useful.Over all it is very good course.

Prof David Spergel provides excellent knowledge along with a wonderful style of presentation filled with examples and interviews to supplement the information. The background knowledge leading up to Exoplanet sessions is invaluable to anyone to develop knowledge in Astronomy as a subject. Wonderful course!

I loved LOVED this course! It was super interesting, intriguing, and kept me constantly questioning everything. I genuinely enjoyed this course. The professor was great, and he knew how to keep his students involved.

I learned a lot about the Universe and found Professor D. Spergel a great instructor. Writing the 3 essay's brought me back to my student day's and was very refreshing!

Un curso excelente que tiene muy buen esquema en su método de enseñanza, cumpliendo con la formación del estudiante en las diferentes áreas de la Astronomía.

This course changed the way i thought about universe and has helped me a lot. Professor teaches things in most easiest way and makes astronomy very easy

I am currently looking todward discovering other planets in other solar systems that have life like planet Earth. Amazing!

It is a great ride so far. Good refreshment of basic astronomy. I highly recommend it. Very clear lectures too.
