Bizarre Signals from Voyager 1: What Are They?

Voyager 1, which has been traveling through interstellar space for more than 45 years, suddenly began to send strange signals to Earth. Even more bizarre, there are no signs that the probe has broken or anything. Scientists from NASA are desperately trying to find the reason. Thanks to Voyager, we discovered several new moons of Jupiter and a previously unknown system of its rings and learned that Jupiter's famous Red Spot is actually a giant, super-fast storm. So, what could be producing these mysterious signals?
