What are the the structures and atmospheric compositions of exoplanets (planets beyond the Solar System)? Do they have strong magnetic fields and if so, how do those fields interact with their parent stars? What are the properties of those stars and their flare and spot activities? These questions are key to answering the question: "Can an exoplanet support life as we know it?" Accurate stellar properties are required for accurate values of exoplanet sizes and masses, and to understand conditions on (and inside) those worlds. What are the detailed birth processes of other suns and planetary systems? What are the properties of a red giant star (the fate of our Sun just before death)? What are the conditions inside hot massive stars (and in their strong winds) before they explode as supernovae, injecting heavy elements into space and influencing future generations of stars and planets? We must have better answers to questions like these if we're to improve our reading of the opening and closing chapters of the biography of our Sun and Solar System.

系外行星（太阳系以外的行星）的结构和大气成分是什么？它们是否有很强的磁场，如果有，这些磁场是如何与它们的母星相互作用的？这些恒星的性质及其耀斑和黑子活动是什么？这些问题是回答这个问题的关键：“系外行星能像我们所知道的那样支持生命吗？“准确的恒星属性是系外行星大小和质量的准确值所必需的，并且要了解这些世界上（和内部）的条件。其他太阳和行星系统的详细诞生过程是什么？红巨星星星（我们的太阳在死亡前的命运）的性质是什么？炽热的大质量恒星内部（以及它们的强风中）在爆炸成为超新星之前是什么样的条件，将重元素注入太空并影响未来的恒星和行星？如果我们要提高对《太阳和太阳系传》开篇和结尾章节的阅读水平，我们必须对这些问题有更好的答案。
