establish there is all this astronomy是什么语法

求详细语法分析：

We've established there is all this astronomy.

我们已经建立了所有这一切的天文学。

《牛津》establish

to discover or prove the facts of a situation

establish that…

They have established that his injuries were caused by a fall.

所以网友的句子就是这种用法，establish后接that从句（that省略了）：

We've established （that）there is all this astronomy.

我的直觉是

We've established there is all this astronomy.

= We've established all this astronomy that there is.

给点上下文才能确定
