BEIJING, Dec. 4 (Xinhua Zhang Mengran) According to the physicist's network 3 news, ESA 's Comet Rosetta mass spectrometer collected more than 35,000 dust particles, including the most primitive known carbon-rich material, after analysis of comet 67P / Chulyumov-Gresimenko chemical composition list.
researchers say the comet's composition has barely changed since the solar system was formed.
Comet 67P/Chuliumov-Gresimenko (comet 67P) was born about 4.6 billion years ago in the early days of the solar system, with an average diameter of about 4 kilometers, and is considered a flying "fridge" that holds the most primitive material.
the Rosetta comet probe, the European Space Agency's unmanned spacecraft program, was launched in 2004.
August 2014, the Rosetta comet probe and the Philae lander arrived at the target comet for sampling and analysis.
, researchers, including scientists at the Max Planck Institute for Solar Systems (MPS), published in the Journal of the Royal Astronomical Society, said they used the comet's secondary ion mass spectrometer (COSIMA) on the Rosetta probe to examine the composition of comet 67P from August 2014 to September 2016.
the instrument can analyze the nature of dust particles released by the comet's nucleus, including the determination of its composition and whether it contains organic matter.
mission, the COSIMA instrument collected more than 35,000 dust particles, the smallest of which was only 0.01 mm in diameter and the largest one millimeter, eventually helping the team get a list of the comet's compositions and an overview of its chemical elements.
scientists believe that the material formed comets in the early days of the solar system, and that its composition has changed little since its formation because of its very low temperature.
mastering the chemical elements of comet 67P means understanding the original chemical composition and state of the solar system.
at the same time, the probe of comet 67P is also expected to solve the mystery of the birth of life on Earth.
scientists believe there is organic matter and water necessary for the evolution of life in comets.
the early days of Earth's formation, a large number of comet impact events or water and organic matter brought to Earth, starting the evolution of life on Earth.
editor-in-chief circled the dust on this ancient comet, not ordinary dust, but the book of life in the solar system.
the Rosetta probe had completed its journey, it had acquired a large amount of data and images of comet 67P.
we already know that comet 67P has dust, the surface is dark, the gas is very "unpleasant", and now we have a better understanding of its chemical composition.
the next question is - how did these chemicals come about? Did it crash out, or did the comet come with it? Scientific issues are like Russian sets, come up with one, and one.
have no definite truth, only eternal quest.
