About the Course

How are astronomers approaching their search for life in the universe? What have we learned from the surge of exoplanets discoveries? How likely is it that Earth does not host the only life in the Universe? In this course we explore the field of astrobiology, an emerging multidisciplinary field. Progress in astrobiology is driven by telescopes on the ground and in space, and by new insights on how life emerged on Earth and its diversity. The topics in this course range from the science of how exoplanets are detected, to the chemistry that supports the argument that the ingredients for life are common in the Universe. We will follow the analyses of experts in chemistry, astronomy, geology and archaeology to build a strong foundation of understanding. By the final assignment, students will be equipped with the knowledge necessary to identify what makes a planet habitable, and how likely it is that life exists there. Students will graduate from this course informed about one of the most exciting fields in all of science, and ready to discuss the current exoplanet news stories and discoveries. Materials for this course were developed by Dr. Chris Impey, Professor of Astronomy, Xana Riabokin, Instructional Designer, and Matthew Wenger, Education Program Manager....

This is my first course in coursera. The material and explanation given by the instructor was awesome. I really learned a lot. Peer graded assingments really helped me to knew the concept very well.

An interesting course that covers a wide variety of topics related to astrobiology, using lectures that provide useful info and interesting points for thought. The 'audit the course' tests are generally quite easy although at times the questions are a bit vague so that it's easy to give "wrong" answers, but it's no great effort to redo them. I can't say much about the graded-assessments as I only went through the audited route but I noted the discussion forums full of the "please assess my assignment" please characteristic of this approach, no idea how many of these please fell on deaf ears. The major criticism I would have is that the videos need correction and as they are marked copyright 2018 and it's now 2024 this has been the case for six years and no-one's been too bothered. Some of these "mistakes" aren't all that big a deal - obvious mis-statements in the lectures or the fact that more exoplanets have been discovered in the intervening years - but there are some scientific errors that should be sorted out (shouldn't have happened in the first place) and it would be handy to update to cover developments arising from JWST among others.

The course is great for beginners in this field. I find the live sessions great, for we can ask questions in real time. The assignments are really good because you get to analyse data and include your creativity in the essay. However, I think the course could be more challenging.

This is an excellent course. The material is presented clearly. The assignments are challenging but not too difficult for a group which likely included people who are taking the course only out of curiousity.

I loved this course, especially the peer-reviewed assignments, it was really exciting to write those assignments and review others, which gave me understanding of how other people thinks

A good course in general. Prof. Impey is very clear, but I cannot agree with him about the Evolution. It's a theory full of gaps: more myth than science.

Excellent course by Prof.Chris Impey. If you want a deeper overall understanding of Astronomy, I would recommend the other course by the same professor.

Wonderful course in my view for space lovers and for those who pursue their career in this field.

O curso tem um questão relacionada a equação de Drake q não tem resposta objeiva. Temos que advinhar valores o que torna impossibvel a solução. Muito fristante.
