What is the "Interstellar Visitor"? Astronomers at Harvard University in the United States published a paper in the latest issue of the Journal of Astrophysics, saying that they have confirmed that the meteor CNEOS2014-01-08, which broke into the Earth's atmosphere in 2014, came from another star system, , and is the first interstellar visitor known to the Earth to date. three years earlier than the famous " Aomuamu ". And these institutes said: 3.5 billion years ago, the "seeds of life on Earth" came from another star system.
What is "Oumuamu"?
Oumuamua, alias C/2017 U1 (PANSTARRS), A/2017 U1, 1l/2017 U1) is the first interstellar object known to to pass through the solar system. Oumuamua means "scout" or "courier" in Hawaiian . On October 19, 2017, it was discovered by scientists. The diameter of Oumuamua is in the order of 100 meters and rushes into the solar system from the direction of Lyra at a speed of about 26 kilometers per second, almost perpendicular to the ecliptic surface. It is a cigar-shaped, about 400 meters long and 40 meters wide, reddish in color, with a solid surface, but cannot be distinguished or made of rock or metal. is the first time that humans have discovered exoplanetary objects in the solar system.
"Seed of Life on Earth"
"Seed of Life" is the source of human evolution . Darwin wrote in "Theory of Evolution" that humans evolved from ape , Chinese scientists confirmed that humans evolved from ape , and the evolution process from fish to humans takes 500 million years. It has experienced the earliest jawless evolution into jawed and meat-finned fish, and then landed onto the land and turned into amphibians and mammals, and finally evolved into humans.
summary
Currently Harvard paper pushes the "seed of life" to 3.5 billion years ago, and speculates that it comes from another star system. This discovery also marks the changes brought about by science, but to the present development of science and technology, we still don’t know where we come from?
