The first interstellar object that came to Earth
One over Papua New Guinea on January 8, 2014fireballWas confirmed.
A fireball is a small one that burns out and explodes in the atmosphere.meteoriteTherefore, it is not unusual for the phenomenon to be observed on the earth.
This fireball will also be analyzed later.It was only 0.45 meters in diameter and burned out in the sky without affecting the ground.Is reported.
However, this meteorite had some notable features.
The speed of this meteorite isIt exceeds 210,000 km / h, and its speed is far from the meteorites that orbit the solar system that are normally seen.That’s how it was.
As a result of further analysis including the orbit that came, thisMeteorites are 99% certainty, interstellar objects flying from deep in the galaxy, far beyond the solar system.It was shown that it could be.
This report was compiled and published in a dissertation by two astronomers at Harvard University in 2019.
The arrival of meteorites themselves is not uncommon on Earth.
But when it comes to interstellar objects, the story is different.
Meteorite is far awayuniverseMany people may have the image of flying from.
ButPrevious asteroids observed on Earth,cometMeteorites are all friends in the solar systemIt is.
Asteroids are like the remnants of the formation of the solar system, which exist primarily between Mars and Jupiter, and do not usually come from far away space.
Comets come primarily from the Edgeworth Kuiper belt and Oort clouds on the outer edge of the solar system, far from Earth, but still within the solar system.
in shortMeteorites that come to Earth have a range of orbits and velocities.It is.
As a matter of factUntil now, almost no celestial bodies that came from outside the solar system have been confirmed on Earth.。
Interstellar objects that fly across the sea of stars from other star systems are extremely rare.
So farThe only reported interstellar object is “Oumuamua」only.
Even if you are not interested in astronomy, you may have heard of the asteroid Oumuamua somewhere.
Some might have wondered what was so special, but the reason Oumuamua is so special is that this asteroid is likely to be the first interstellar object observed from Earth.
And it was in 2017 that the discovery of Oumuamua was reported.
The fireball report over Papua New Guinea, which we are talking about this time, was in 2014, so if this is the case, it means that human beings were observing the first interstellar objects three years before the discovery of Oumuamua.
Moreover,Oumuamua is now taking a course away from Earth without approaching it.。
After all, it seems likely that even a telescope will leave somewhere without knowing the details.
on the other hand,Papua New Guinea’s fireball is falling to Earth。
Even if the possibility is shown, it is an important report.
The two researchers published this important paper on a preprint server and submitted it to The Astrophysical Journal Letters, a scientific journal on astronomy.
but,The paper was not peer-reviewed and was left unattended for three years after submission.It is.
Why did that happen?
It’s thisPaper validation was hampered by government-controlled sensitive dataThe person concerned says that it is a body.
When asked that much, was there anything wrong with the US government about the first interstellar object of humankind that would not be known to the general public? I want to think that.
If you’re a conspiracy theorist, there’s still government hiding of information! You might smile when the Roswell incident and Area 55 are true.
So what is the reason why peer review of papers was actually stopped due to government information?
