A while ago I asked about a translation for "star age" to ancient Greek. I ended up with the wording: Astereaon. I am now curious as to what the translation would be for something like: "The age of star travel / exploration" or "star age exploration". I am unable to find some of these words or base words on some ancient Greek translation websites so I was thinking I could ask that here.
As a note, this is for a series title of a bunch of science fiction stories. I am also open to a Latin translation of this as both languages /histories play a part in the series.
