‘Alien’ signal was likely a very big truck

There’s no doubt an extremely bright fireball careened through the atmosphere north of Papua New Guinea on January 8, 2014. It’s also true that divers recovered materials at the bottom of the ocean last year near where many experts believed the object landed—and that prominent Harvard astrophysicist Avi Loeb theorized some of these metallic spherules were possibly of “extraterrestrial technological” origin. But as to the ground vibrations recorded at a seismic station on Manus Island during the same atmospheric event? The explanation is likely much more mundane.

“[T]hey have all the characteristics we’d expect from a truck and none of the characteristics we’d expect from a meteor,” Johns Hopkins planetary seismologist Benjamin Fernando said on Thursday.

Fernando and his colleagues will present their findings on March 12 during the annual Lunar and Planetary Science Conference in Houston, Texas.

Although Fernando’s team concedes it’s difficult to prove what something isn’t through signal data, it’s pretty easy to highlight the characteristics it may share with existing, explainable seismic info.

“The signal changed directions over time, exactly matching a road that runs past the seismometer,” said Fernando.

To further bolster the much more everyday explanation, researchers also utilized data collected during the 2014 event by facilities in Australia and Palau originally built to measure nuclear test sound waves. After factoring in those recordings, Fernando’s team revised the previous location estimations for a more exact spot of the atmospheric occurrence—an area 100 miles away from the original region.

“The fireball location was actually very far away from where the oceanographic expedition went to retrieve these meteor fragments,” Fernando said of the 2023 recovery trip. “Not only did they use the wrong signal, they were looking in the wrong place.”

The team also doesn’t mince words in their new paper, “Probably Not Aliens: Seismic Data Analysis from the 2014 ‘Interstellar Meteor.’” Of the alien theory, the researchers “consider it to be at best highly overstated and at worst entirely erroneous.” And of the material recovered last year, “poor localisation implies that any material recovered is far less likely to be from the meteor, let alone of interstellar or even extraterrestrial origin.”

Given NASA’s estimate that around 50 tons of meteoritic material bombards Earth every day, Fernando’s team says it’s definitely possible some of those fragments retrieved from the ocean floor may indeed be from some other meteorite. Regardless, they “strongly suspect that it wasn’t aliens.”

Disappointing? Perhaps. But there’ll probably be plenty of new UAP sightings to parse in the future—especially if people take up the government’s offer to submit their own inexplicable events.
