Scientists have discovered 24 planets that are more livable than the earth. Does the current technology support immigration?

Earth science is a basic discipline to study the process, change and interaction of the earth system, while astronomy is a discipline to study the structure and development of celestial bodies and the universe in space. These two seemingly independent scientific systems are inextricably linked.

Meteorite event is the best example to illustrate the interaction between astronomical factors and earth science. The impact of high temperature and high pressure will cause changes in topography and geology, and dust particles in the atmosphere will block sunlight, causing changes in atmospheric composition and seawater temperature. The record and discovery of this astronomical event are inseparable from the study of earth science, and they are closely linked.

Modern astronomy has a relatively systematic observation data in recent hundreds of years, but in order to study whether various astronomical elements have changed during the geological period, it is necessary to study and query the geological records of billions of years. At the same time, the study of the origin and early evolution history of the earth can also be verified by the results of nebula evolution in astronomical research. Therefore, the two complement each other and can complement each other.

In fact, it is mainly because the earth is a celestial body. The origin of the earth and the formation and evolution of the solar system in earth science also belong to the research scope of astronomy. The operation of the earth, the structure of the sphere and the reproduction of living things are closely related to the cosmic environment in astronomy. Therefore, astronomical geology was born, which closely linked astronomy with earth science. The application of astronomical research methods, observation data and research results can better explore and explain the causes and evolution laws of various geological phenomena on the earth.

The trend of multi-disciplinary comprehensive research and cultivating compound talents advocated now will inevitably bring closer exchanges between astronomy, earth science and other disciplines in the future and create more scientific research progress.
