Astronomers have been searching for the vast universe in order to discover foreign civilizations. But for the planet to have life, liquid water must exist. The possibility of this discovery scene seems impossible to calculate, because people have always believed that if a large ice asteroid hits the earth, a planet like the earth will accidentally obtain water.

Now, researchers at the Globe Institute of the University of Copenhagen have published eye-opening studies that show that water may be present in the formation of planets. According to research calculations, this is true for Earth, Venus and Mars.

“From the beginning, all our data indicated that water is part of the building blocks of the earth. And because water molecules appear frequently, there is a reasonable possibility of applying them to all planets in the Milky Way. Professor Anders Johansen (Anders Johansen) of the Center for Star and Planet Formation led the research, which is the key to determining whether there is liquid water, which is the distance between the planet and the star. Scientific progress.

Using computer models, Anders Johansen (Anders Johansen) and his team calculated the speed of planet formation and the basis of the planet. The study showed that it was the millimeter-scale dust particles of ice and carbon-known to revolve around all young stars in the Milky Way-4.5 billion years ago that facilitated the formation of what would become the Earth.

“Until the earth grows to one percent of its current mass, our planet grows by capturing pebbles full of ice and carbon. Then the earth became faster and faster, until five million years later, it became as big as we know it today. During this process, the surface temperature rises sharply, causing the ice in the pebbles to evaporate while falling to the surface. Therefore, even if 70% of the water on the earth is composed of water, only 0.1

% is currently water Anders Johansson (Anders Johansen) said that he worked with his research team in Lund ten years ago to put forward the now-proven theory of this new research.

This theory, called “pebble accumulation”, is that planets are formed by clusters of pebbles, and then the planets become larger and larger.

Anders Johansen explained that the water molecule H2O can be found anywhere in our galaxy, so this theory opens up the possibility that other planets may form in the same way as Earth, Mars, and Venus.

“All planets in the Milky Way galaxy may be formed from the same building blocks, which means that planets with the same water and carbon content as Earth-and thus planets that may have life-will frequently appear around other stars in our galaxy. He said.

If the planets in our Milky Way have the same building blocks and the same temperature conditions as the Earth, it is very likely that they will have the same amount of water and continents as our planet.

Professor Martin Bizzarro, the co-author of the study, said:

“Through our model, all planets get the same amount of water, which suggests that other planets may not only have the same amount of water and oceans as on Earth, but also have the same number of continents. He said that it provides a good opportunity for the emergence of life.

On the other hand, if you find out how much water there is on a planet at random, the appearance of the planet may be quite different. Some planets are too dry to develop life, while others are completely covered by water.

Anders Johansson said: “A planet covered by water is certainly beneficial to marine life, but it does not provide ideal conditions for the formation of a civilization that can observe the universe.”

Anders Johansen and his research team look forward to the next generation of space telescopes, which will provide better opportunities for observing exoplanets of stars orbiting the sun.

The new telescope is powerful. They use spectroscopy, which means that by observing which type of light is blocked by the planet’s orbit around its star, you can see how much water vapor is in it. He said it can tell us about the number of oceans on the planet.
