Star Birth and Death
Stars are the crucibles of heavy element creation, and the chaotic regions of their birth are being understood though long wavelength observations. Gravity is the ultimate victor in the life story of any star, leaving behind the exotic end states of white dwarfs, neutron stars, and black holes.

Complete information for to know the actual situation about Astronomy and good video resources for easy understanding.
i have learned too much about Astronomy, this course is very clear, explained in a very easy way, I am so glad to participate, and I hope have a second part of this course.
this course help me to understand about universe in non mathematical way, without this course I didn't able to understand and learn .
This course is fascinating! Professor Impey is awesome. The lectures are very clear and amusing. I did many Astronomy courses and this one is really one of the best. Also, the Quizzes are easy, not impossible like other Astronomy courses. There are several assignments but they are easy and fun to do. Thanks a lot and many greetings from Spain / Antonia Tejeda Barros
