> One of our chief goals was to apply the power of signal processing to search for weaker signals in the PWS data, which maybe, just maybe, were hiding between and behind the bright plasma oscillation events that had already been discovered. So this doesn't mean that Voyager 1 has entered a new region with different characteristics, just that they've used signal processing to tease a little bit more out of the existing data.
