Back in 2014, an item crashed into the ocean simply off the coast of Papua New Guinea. Information gathered at the time suggested that the meteorite just might be an interstellar things, and if thats true, then its only the 3rd such item understood (after Oumuamua and Borisov), and the first known to exist on Earth. Releasing an undersea exploration to find it would be a long shot, but the scientific reward could be huge.
Called CNEOS 2014-01-08, the prospect interstellar things is believed to have actually measured about a half-meter large, and its potentially interstellar origins were very first acknowledged by then college student Amir Siraj and Harvard teacher Avi Loeb. Using brochure information relating to the items trajectory, Siraj and Loeb concluded that it may be from beyond our planetary system due to its unusually high heliocentric speed– in other words, it was moving at speeds that suggest it might not be bound within the Suns gravity well.
Theres a catch, however. The data utilized to determine the thingss impact with Earth originated from an US Department of Defense spy satellite, designed to keep track of Earthly military activities. As such, the specific mistake worths of the measurement are a thoroughly guarded secret– the US armed force watches out for permitting the precise abilities of their satellite to end up being public domain info. However without these details, much of the clinical neighborhood understandably remains reluctant to formally categorize CNEOS 2014-01-08 as an interstellar object. Siraj and Loebs paper therefore remains unpublished, having not yet passed peer review.

Their claim, nevertheless, was boosted in April 2022, when the US Space Forces Space Operations Commands Chief Scientist, Joel Mozer, examined the categorized data in question and “verified that the speed quote reported to NASA is adequately precise to show an interstellar trajectory.”

The US Space Command verified that CNEOS 2014-01-08 followed an interstellar trajectory in April 2022.
While the main scientific category of CNEOS 2014-01-08 appears doomed to remain in limbo for the time being, the declaration by the United States Space Force was enough to convince Siraj and Loeb of its interstellar origin, and they have now proceeded to proposing possible ways to find the item and study it up close.
Not all hope is lost, as the tracking information from the satellite, integrated with wind and ocean present information, can offer an affordable search area of simply 10km by 10km. Siraj and Loeb propose to do just that, and have teamed up with an ocean innovation seeking advice from business to make it take place.
In an interview with Universe Today last year, Loeb explained that such a search could offer us “the chance to actually put our hands on the antique and find out whether its natural, whether its a rock, or whether, you know, a small fraction of those [interstellar items] might be synthetic.”
Interview with Avi Loeb, April 8, 2021.
Loeb has actually been singing in current years about the potential for interstellar things like CNEOS 2014-01-08, Oumuamua, and Borisov to be artificial objects developed by extra-terrestrial intelligence. “This result does not suggest that the very first interstellar meteor was artificially made by a technological civilization and not natural in origin,” he and Siraj write in their most current paper laying out the ocean exploration. Its clear that Loeb believes it would not injure to go find the object and take a look.
Even if it is just a rock– which is without a doubt the most likely description– itll tell us a lot about the structure of rocky matter beyond our own solar system, and that itself would be a valuable bit of brand-new information.
