Astronomical does not mean extreme; it refers to the distances between stars. Something can be astronomically expensive, it cannot be astronomically cheap. It can be astronomically large, not astronomically small. You might as well say microscopically huge.
Epicenter is not a hip synonym for center, although that's how people are using it lately. It's weird, but what it means is the edge of the center.
