An “interstellar object” came from outside the solar system

It came from outside the solar system.An interstellar being」It was first observed in October 2017.

This heavenly body“Oumuamua.”(meaning “the first messenger from afar” in the Hawaiian language), he passed 24 million kilometers from Earth.

By the time it was discovered, it had already been five days since it passed by Earth, so astronomers could only observe 'Oumuamua, which is far from Earth, and its true identity remains shrouded in mystery.

At the time, some people claimed that 'Oumuamua was a space probe.

However, later research has shown this'Oumuamua is a celestial body of natural origin (such as part of an exoplanet).This view is widely accepted.

And in 2019, as the second interstellar body,Comet BorisovIt was observed, but it also never reached Earth.

However, in 2019, it was discovered that an object that reached Earth in the past was actually an interstellar object.

that itIn 2014, a fireball-shaped celestial object was seen over Papua New Guinea.CNEOS 2014-01-08 (also known as IM1)」He is.

This celestial body will appear in April 2022.US Space Command (USSC)It has been officially confirmed as a possible interstellar object.

The publication of a research paper on “the first collision of an interstellar object with Earth in the history of observation” was prevented due to government secrecy!

In other words, IM1 isThe third interstellar object observed by humansAnd“The first interstellar object to collide with Earth in the history of observation.”That's it.

IM1 can also be called an unknown “gift” from outside the solar system. No wonder so many people are interested in IM1.

Then, a project by a research team led by Harvard astronomer Avi Loeb attempted to recover the “IM1 fragment” that exploded over Papua New Guinea and sank into the ocean.

Based on the vibrations caused by IM1 as it entered the atmosphere, they determined where the piece had fallen and reported that they had discovered part of an interstellar object.

If this is true, humans will be able to analyze matter outside the solar system.

However, there are many scholars who are dissatisfied with Mr. Loeb's report, and some suggest that “Mr. Loeb is wrong.”
