Research: The Milky Way may have a large number of planets with continents and liquid water like the Earth

A new study recently published in the journal “Science Advances” attempts to answer this question. Researchers simulated the formation of planets based on people’s understanding of how the earth and other worlds in the solar system were born. They believe that the Earth may only be one of the planets with continents and liquid water in the Milky Way, which means that people have a good chance to live in other local communities in the Milky Way.
Anders Johansen, the lead author of the research paper, said in a statement: “Before the earth grew to 1% of its current mass, our planet grew by capturing large amounts of crystals full of ice and carbon. After that, the earth grew faster and faster, until 5 million years later, it became as big as we know today. During this process, the temperature of the earth’s surface rose sharply, causing the ice in the crystal to drop to the surface. Evaporates during the process, so now only 0.1% of the earth is made of water, even if 70% of the earth’s surface is covered by water.”
By using this information, the research team simulated the world around other stars Formation. According to the computer model used by the research team, the planet eventually received the same amount of water in the form of ice during its formation. Whether the ice will melt into a vast ocean is only a question of how far each planet is from the host star.
The idea here is that based on observations of other stars and planets, it appears that the same types of matter that make up our solar system are also present around new stars. And how these substances are combined into the final decision of the planet or destroy the system’s chances of sustaining life.
