As Futura explained in a previous article aboutCuriously, it coincided with the October 19, 2017 discovery of an object that was undoubtedly on an interstellar trajectory, the first ever discovered from outside our solar system, as it then appeared, namely 1I/2017 U1. But he is better known as (“ Messenger who came from afar and arrived first in Hawaiian) and its amazing properties suggested that it could be a real interstellar probe of an advanced extraterrestrial civilization.
The vast majority of the scientific community has considered this for some timeand so she was particularly upset by the insistence of about as can be seen when reading the review of the . Chair of the Astronomy Department at Harvard University (USA) from 2011 to 2020 and very involved in the project — a beam-powered photonic nanoveil to the the next in the Alpha Centauri system — Loeb went on to defend the ET thesis for ʻOumuamua in a book translated by and which was published by Editions du Seuil under the title The first sign of extraterrestrial intelligent life.
But before that, as Futura explained in the previous article below, which we should read before proceeding to read this article, Loeb had filed 2019a work with his student and colleague Amir Siraj, also a theoretical astrophysicist at Harvard University and indeed lead author of the 2019 paper.
The two men theorized that the first object of interstellar origin was actually discovered on January 8, 2014. It was a small celestial body about 0.45 meters in size that would have exploded in the sunof the earth just above Papua New Guinea, penetrating its upper layers at a speed of about 210,000 km/h.

Interstellar traveler confirmed by US Space Command
However, Siraj and Loeb relied on information from theUS Space Command, That is, the United States Space Command (USSC), one of the eleven joint combat commands of the United States Armed Forces, responsible for space operations. They therefore did not have access to all the data proving the existence and properties of the object that crashed in 2014, so the uncertainties about the speed and trajectory did not allow to determine beyond a doubt that it was in fact an interstellar visitor.
But after the fight with the military administration withto detect possible explosions of nuclear weapons in the Earth’s atmosphere (this is prohibited by a ), Loeb and Siraj have seen their efforts rewarded as the USSC has just officially confirmed that its own scientific experts, on the advice of had come to the same conclusion as the two men and that they had therefore validated their thesis.
This confirmation takes the form of an internal memo dated 01.01ah March 2022 and shared onthis April 7th by Lt. Gen. John E. Shaw, Deputy Commander of the USSC.
The explosion of the small celestial body happened not far from Manus, one of the Admiralty Islands, the fifth largest island of Papua New Guinea. Siraj wonders if oceanic expeditions would not make it possible to find the remains of this interstellar body on the seabed nearby, just as one can find isolated meteorites on dunesin one or in .
‘Oumuamua and Borisov were the first two interstellar objects found in our solar system. And as the Vera C. Rubin Observatory nears launch, it will improve our ability to detect interstellar objects. How many interstellar objects are there in our galaxy? How many interstellar objects in our solar system? Could some have landed on the moon and been held there?

An interstellar meteor reportedly fell to Earth in 2014
Article bypublished on 04/21/2019
Dozens of meteorites fall to earth every day. Harvard researchers believe they have discovered at least one among them(they pinned three candidates) who would be of interstellar origin, that is, who would come from somewhere else, from another planetary system like ‘Oumuamua.
Featured in the ranking of time magazine One of the 25 most influential people in space, Abraham Loeb (or Avi Loeb), the esteemed head of Harvard University’s astronomy department, made himself known to a wider audience a few months ago with the publication of a widely acclaimed study he suspects that the now famousFirst never discovered is an artifact from somewhere else.
To explain hisSo special and his behavior, he and Shmuel Bialy actually don’t rule out that it is . An assumption that not all of his colleagues share and that is controversial. “I can commit suicide professionally if I’m wronghe told the newspaper. . This gives me more time for science. But if I’m right, it’s one of the greatest discoveries in human history.” he continued.
“These high-ranking personalities say themselves that this object has very special properties”
Note that some of his peers are just as intrigued as he is: “These high-ranking personalities say themselves that this object has very special properties. But they dare not report it publicly..
Believing that 1I/2017 U1 – official name of ‘Oumuamua – is not the only or even the first visitor from elsewhere in our solar system, Avi Loeb and Amir Siraj, a Harvard student, are following in the footsteps of the possible small interstellar Travelers who would have ended their journey on earth. They found three of them, one with strong suspicions that it was not native to the solar system.
Billions upon billions of interstellar meteorites across the galaxy
The not very large object – about 90 centimeters – entered the Earth’s atmosphere on January 8, 2014 at 17:05 UT over the southwest Pacific Ocean, not far from the island of Manus in Papua New Guinea. It is one of the Cneos detectors (Center for Near-Earth Object Studies) who discovered it. The two researchers spent thirty years studying data collected by the various observatories in this American program.
It was the speed of this invader that made her question. And it was the high-velocity meteorites that they looked for in the archives because they probably benefited from an acceleration within another system. The object was speeding at about 130,000 miles per hour as it entered the atmosphere. Additionally, the direction of the room he came from helps convince her that he wasn’t from here. For one of the other two candidates, they dug up the two in the catalogueare rather skeptical. Although it’s as fast as the first indicates that it belongs to our solar system.
Three possible interstellar meteors – and possibly more – to be stranded (disintegrated in its atmosphere) on Earth in 30 years, or one every 10 years on average, that’s well over billions of years. The two researchers calculated that there would be around a million of these objects, e.gof 150 million cubic kilometers (a ), all in one .
So is our planet often watered by these little rocks ejected from other stars? This possibility is taken very seriously by astronomers. “You can imagine that if these meteors were ejected from a star’s habitable zone, they could help transfer life from one planetary system to another.”, emphasizes Avi Loeb. The author and co-author of more than 700 scientific articles wants to learn more about her topicspoint to the fastest meteorites as soon as they are discovered to infer their composition.
