Question

What do you think the phrase treasure house is synonymous with in this passage please help?

Answer 1

I think it is either talking about space or earth.

Answer 2

In order to answer your question I'm going to use my mysterious ability to look into the future. You didn't attach the part of the story that talks about a treasure house. I think on the next page it's going to talk about putting a telescope in orbit above the atmosphere. And it's going to say that a telescope above the atmosphere is a treasure-house of new information that we can't see down here.
