"Omuamua," which entered the solar system in 2017,
Controversy with general asteroids and comets
Harvard vs. "artifacts created by extraterrestrial life"
The first extraterrestrial object discovered by mankind is Omu Anua. – Southern Observatory of Europe
'Could it be a wanderer in the universe or an alien sent by an alien?'
On October 19, 2017, an object was first captured on the Pan-STARRS 1 telescope in Hawaii. This mysterious object with an average diameter of 230 meters showed different characteristics from an asteroid or comet composed of ice or rock. There are also traces of organic matter on the surface.
Especially in the early entry process, the object moving at a speed of 26km per second was speeding around the sun unexpectedly. The normal object has passed through the sun and undergoes gravitational resistance, resulting in a decrease in velocity, which is the opposite.
It turned out to be an extraterrestrial interstellar object that found the solar system. It is the first time that humans have flew from a distant universe and discovered an interstellar object that crossed the solar system. And it was named Oumuamua 1I / 2017 U1, the term Hawaiian Aboriginal, a distant communicator. However, no one has come up with an answer on what the identity of Omua-A is and where he comes from.
It was a little bit of a turmoil in the scientific community as a result of the research that Omu Amou was made by extraterrestrial creatures a few years ago and could be a trace of a probe sent to space. Professor Abraham Rove, a professor of astronomy at Harvard University in the United States, published an analysis of the results of an alien creature, Omuuman, who was faster near the sun, in an article in the international journal "Astrophysical Journal Letters"
I have summarized Harvard 's researchers' interpretation of the question that Omu – mum threw.
▲ Near the sun, there is no celestial body that speeds up like Omuumua.
= This is a comet. Due to the heat of the sun, ice on the surface melts and can escape in gas form. The more gas comets, the faster. So it was presumed that the surface of condensed ice and dust was getting faster as Omuamu came off. But it turned out to be a false analysis. The surface did not fall off.
▲ Why do you think the surface did not fall off?
= If material is dropped from the surface, the rotation speed of Omuamua should be accelerated at the same time. According to the analysis of the light from Omuamua, it was confirmed that it rotates at intervals of 6 ~ 8 hours depending on conditions. This is the result of ignoring the ambient vibration. The average value did not change much when passing near the sun. This is why it is difficult to define Omuama as a comet.
Trajectory (left) that Omunuoga enters the solar system and escapes. It was expected to move to the red track, but near the sun it was faster than expected and actually moved along a blue trail that was about 40,000 kilometers away.
How did the speed of Omu Noah accelerate
= There is 'Solar Sale' technology that uses the sun's radiant energy to navigate the universe. Make a thin metal film into a sail shape and accelerate to sunlight (photon). The Icarus project in Japan and the US Star Space Initiative, a private space company, are attempting this technology. When Omuamua does not show comet-like features, it is estimated that Omuamu will be flying in the Solar Sale mode.
If the alien species sent it, there must be a device to send and receive signals.
Many researchers have been measuring the signal from Omu Amua in the near future, but there have not been any artificial signals yet. However, only narrowband signals have been analyzed and analysis is still going on. There is also a story that it may be trying to transfer space instead of radio waves like SF movie "Star Trek".
If there are extraterrestrials, why did they send Omuamia over millions of years?
= I do not know. One possibility may not have been a specific intention. This is because some of the remnants of a probe that has been launched into space by extraterrestrial creatures with a higher level of technology than ours may have flowed by accident.
Is extraterrestrial life the most likely interpretation?
There is currently no way to prove. We can not rule out the possibility of an asteroid or comet that absorbs solar energy from the surface.
There are many objections to Harvard's interpretation. Although the speed is still unresolved, Omu-Amo moves on the same trajectory as a comet and has a much more complex vibration pattern than the solar sail vibrates under the sun's pressure. The analysis of the identity of Omuamua remains mostly in hypothesis. Omuumua was confirmed to have completely deviated from the solar system toward the Pegasus constellation in September.
