Windows of Astronomy

?

Full marks for the inquisitiveness of clicking on the ‘?’.  A century ago at the time of writing, nine of these ‘windows of astronomy’ did not exist, though UV, radio waves and X-rays had been discovered and satellites conceived.  Dark matter seems to make up about a quarter of the matter in the universe but we know tiddlywinks about it.  Indeed, we hop from one conjecture to another speculating what it might be.  With more definite knowledge, that window may at least open wider and generate new knowledge.    Are we sure that there are no other windows?  Of course not.  Notable ancestors, scientists among them, had the hubris to think that most of what could be discovered had been.  They were wrong.  On the other hand, the number of windows of astronomy will not expand for ever and discovery must stop sometime.  Maybe this is it.  Perhaps I’ve been reading too much science fiction but it seems likely to me that we haven’t exhausted our means of perceiving the universe at large.  Speculation is futile, or at least science fiction at the moment.  There is plenty to keep astronomers looking through the windows we know about for a long time to come.

Lunar Base

A great many unmanned probes have already looked out from space. It's not clear that a lunar base would uncover a new window on the universe.
