Xinhua News Agency, Los Angeles, December 6 (Reporter Tan Jingjing) The cigar-shaped object discovered last year is considered the "first interstellar visitor" of the solar system, and its true identity has been highly worried by global astronomers. According to a recent study by the American Institute of Alien Civilizations Research (SETI), this celestial body was not detected as "artificial" radio signals, but this can not be dismissed as "unnatural origin."
In October last year, researchers at the University of Hawaii in the United States observed this mysterious object for the first time. It is dark red and has a length of 10 times the width, similar to a cigar shape. Astronomers called him "Oumuamua," meaning "distant messenger" in Hawaiian), and made several assumptions about his identity.
It has been speculated that this celestial body may be a comet or an asteroid, but observations show that the celestial body has no "tail" characteristics and is flying faster than an asteroid. Because of the strange form of "Omo Mo," some people think it is necessary to detect if it emits radio signals that can reveal signs of alien intelligence life.
Researchers at the Institute of Alien Civilization used the Allen Telescope array from November 23 to December 5 last year to observe "Omo Mo" when it was about 270 million kilometers from Earth. Researchers have attempted to detect "artificial" radio transmission signals to confirm whether "Omo Momo" is just a "stone" ejected by gravitational interaction between galaxies, or otherwise.
The team used a broadband correlator of the Allen Telescope array to look for radio signals at frequencies between 1 and 10 GHz with a resolution of 100 kHz, but did not detect "artificial" signals. The article will be published in the February issue of the British Journal of Star Navigation.
"We tried to find radio broadcast signals to see if Omo Mo was using artificial technology, but we did not find the relevant signs." Our remarks did not eventually rule out the unnatural origin of & # 39; Omo Mo, which is studying their construction provides important data, "said Grieg Happ, the lead author of the study.
Founded in 1984, the Alien Civilization Research Institute is located in Mountain View, Northern California, USA, and is a research organization with a mission to search for alien intelligence.
