Constellations are still useful for teaching the stars, but it doesn't mean that mythical beings embedded themselves in the sky. Discovering that the earth was not the center of the universe pretty much did invalidate everything we know about cosmology. Newton's laws are fine for now, but once again, it doesn't make them truth. It makes them useful tools. We can't confuse useful for true, that's the entire point, because one day, even if it's still useful, there's a chance it will be found to not be true.
