The content of these lectures was great, and I learned quite a bit. However, there were two annoying issues. One was that the individual segments broke at odd points, sometimes in the middle of a sentence. The other is that the presentation used a screen to illustrate some points, but often that screen was not well-shown in the recording. I've noticed this latter problem in other World Science U presentations.

Great lecture Professor Sasselov. I have learnt a lot and at the same time fired up to learn the more.

Thank you Dr. Sasselov for the lectures. The ice at ocean bottoms is something that will be good to continue pondering.

In finding planets and having a list, i am ignorant if Fermi Bubble X-rays are factored into goldilocks concepts. Abundant and unusual by-products sound as if remote sensing factors out galactic location in proximity to Fermi Bubbles. Sputnik as a start of 60 years of remote sensing is good History. History cures technology.
