A loud scream has been detected in space by a NASA probe. Voyager 1, a space probe that is currently over 14.1 billion miles from Earth and travelling at roughly 38,000 kilometres per hour, heard the alarming sounds. In reality, scientists just reported that Voyager 1 had gone over the border of our solar system, which is where the noise was detected.
The probe was launched 44 years ago and is currently travelling through the interstellar medium, which, according to NASA, is beyond the influence of our Sun.
It detected a signal that was six times stronger than cosmologists had predicted. The enormous signal puzzled scientists since it was too loud to be early stars and significantly higher than the projected total radio emission from distant galaxies. Even now, experts are baffled as to what is causing it. Furthermore, it might make it difficult to find signals from the first stars that were made after the Big Bang.
Because the roar does not seem to match the geographical distribution of Milky Way radio emission, it is most likely not emanating from inside our galaxy. Nobody can tell for sure that the signal isn’t coming from somewhere closer to home, but the smart money is on it originating from somewhere else.
Although it’s doubtful that ARCADE’s equipment would have detected radiation from any of them, some scientists have speculated that gases in massive clusters of galaxies may be the cause. Similarly, it’s possible that the signal was picked up by the first stars or that it’s coming from a slew of normally weak radio galaxies whose combined influence is being picked up. However, if this were the case, they’d have to be packed so densely that there’s no space between them, which seems doubtful.
