24 Billion km Away, Voyager 1's Signal Changed — And No One Knows Why

In November 2023, NASA scientists discovered that Voyager 1's signal, which had been transmitting reliably for 47 years, suddenly began sending scrambled data that made no sense. Despite extensive investigation of hardware, software, and transmission systems, the probe was functioning normally while its data appeared corrupted. Scientists proposed three theories: cosmic radiation damaging the memory chip, unknown interstellar forces affecting the signal, or the possibility that Voyager 1 encountered something that left a mark on its transmission. This mystery highlights the challenges of maintaining communication with spacecraft billions of kilometers away and the unknown phenomena that may exist in interstellar space.
