报告摘要：There are three “extremely large telescopes” under development internationally. There are very good scientific reasons for these ambitious developments, but they are challenging engineering projects, and very costly. For decades there have been debates about the relative merits of telescopes of different sizes, with no clear consensus on the balance between investments at various scales. This talk will examine one area of research which is advancing very rapidly, exoplanet research, to explore this issue. The field is too new to offer any firm conclusions, but there are very interesting questions to discuss.
