According to foreign media reports, since the beginning of the space age, cosmologists have been wondering whether the planets near the earth are pregnant with any life, especially microbes such as bacteria, archaea and fungi. Some scientists have also speculated whether they have missed something, and viruses have become a target for scientists looking for extraterrestrial life. < / P > < p > NASA’s virus focus group is trying to integrate virological advances into cosmobiology to study the origin, evolution and distribution of life in the universe. By providing such a platform for scientists interested in cosmic virology, NASA hopes to develop “new areas of research to advance our understanding of how viruses affect the origin and evolution of life on earth, and perhaps other planets in the solar system.”. < / P > < p > recently, the NASA sponsored Working Group on space virology has attracted many experienced scientists whose research fields cover multiple directions. With the active participation of these interested researchers, these working groups are expected to prompt NASA to continue to allocate more funds for space virology research. < / P > < p > on our planet, microbes such as microfungi, archaea, bacteria, and amoeba are almost everywhere. Cosmologists have long considered the possibility of microbes living in other parts of the solar system, such as Mars, Venus, and the moons of Jupiter and Saturn. However, on earth, the number of microorganisms is not as much as that of viruses, and they are regulated by viruses. In essence, viruses are not “alive.”. But the number of viruses is more than ten times larger than all living creatures on our planet. There are so many viruses on our planet that if each virus is linked head to end, the virus chain can extend as long as 100 million light-years. As the new coronavirus pandemic has proved, viruses can significantly affect life on earth. However, extraterrestrial viruses have traditionally not been a major search target for cosmobiology. Cosmologists are just beginning to integrate their knowledge of viruses into our understanding of the origin, evolution and distribution of life in the universe. For many years, cosmobiology has been an important part of the study of life history: by studying the environment similar to the early Earth environment or found on other planets, scientists can study the environmental conditions that gave birth to life. Although virological research has always focused on viruses that affect human health, scientists have been able to better understand the various roles that viruses play in our world. Some viruses regulate the health of humans, animals and plants, providing organisms with physical and chemical tools to resist pathogens and environmental stress. Viruses also often co evolve with their hosts and drive host evolution, including the development of mammalian placentas. Viruses also regulate nutrient conversion in the ocean, breaking down cells and releasing nutrients vital to marine ecosystems. < / P > < p > viruses are unique in nature – although they are composed of proteins and nucleic acids similar to living cells, they cannot reproduce independently. The discovery of viruses on Mars or Saturn’s moons will be a revolutionary breakthrough in cosmic biology. Assuming that viruses replicate in the same way in various systems, the discovery of viruses can indirectly indicate the existence of cell life. < / P > < p > regarding viruses as a target for extraterrestrial life does not even require extensive adjustment of instruments or technologies. At present, the technology development used in the space shuttle is mainly to analyze long-chain polymers such as DNA and RNA. In the future, it will be able to detect living cells, viruses and even unconventional life forms not found on earth. In fact, it is biased to say that people do not avoid the virus as much as possible. The new coronavirus pandemic has proved that these tiny biological factors have the potential to harm human health and greatly change social behavior. However, the fact is that although some virus strains have a great impact on human health, the vast majority of viruses only infect microorganisms. Cosmic virology can “change the mentality of ordinary people to talk about viruses”, because viruses are not always “tiny demons that destroy the world”. “Viruses” are vital to life on earth – perhaps they are just as important outside the planet. Cosmic virology can also help scientists continue to improve their understanding of viruses on earth. Together with the search for extraterrestrial viruses, this field can provide clues on how viruses can help shape the origin and evolution of life, as viruses already exist in the early stages of life on earth. In addition, research can help us better understand the role of viruses on earth – “especially in the early Earth environment and similar extraterrestrial ecosystems.”. Cosmic virology really breaks through the boundary of what kind of life or signs of life you are looking for. There are so many things that human beings don’t know. This mystery and unknown fascinates us deeply, because it shows that everything is possible. Didi Qingju bicycle has entered 150 cities
