關於此課程：在这个免费的课程里学习目前的太阳系探索背后的科学。用物理、化学、生物和地理的法则去理解关于火星的最新的新闻，理解外太阳系，思考太阳系外的行星，寻找附近环境以及更远区域的可居住性。这个课程普遍在本科级别的数学和物理知识上讲授，但是大多数的概念和课程并不需要这些知识就能理解。小测和期末考试会考察你是否能对学习过的材料进行批判性思考，而不是简单的记忆事实性的知识。这个课程应该有些难度，但会很有收获。

Excellent course and instruction. I would highly recommend this challenging course to anyone wanting a solid science update on our solar system.
Fantastic course from start to finish. Very insightful, engaging and thorough. The material was excellent and of the right level of difficulty. Would highly recommend.
Awesome course! A lot of information, I have been taught Master courses which teach you much less than this one. There are a few cons though. No Mercury, nor Venus units (they are barely mentioned through the entire course). And it would be nice to have access to the oficial notes, if there are, so we can take a look before watching the lectures ( I understand that this could be too much for an online course).
I have taken and taught many online courses using various platforms. This is by far the best courses I have taken. It is well organized and the content cover is beyond my expectations. Excellent course!
