Planets containing melt water can be endemic in our own galaxy, greatly increasing the chances of “Other Earth” being able to support life forms. That is the surprising conclusion of a study by astronomers that reveals that water may be present when all planets are formed.
Published in journal Advances in science, a study by researchers from the Center for Star and Planet Creation at the GLOBE Institute at the University of Copenhagen, Denmark, found that in the formation of Earth, Venus and Mars – three of the rocky planets in the System We have solar.
It is often assumed that water entered the Earth through impacts by frozen asteroids and comets.
“All of our data shows that water was part of the Earth’s building blocks from the beginning and because the water molecule is a frequent occurrence, it is reasonably probable that it applies to all the planets in The Sweet Way ”, said Professor Anders Johansen, who led the study. “The point is that melting water is present at the distance of the planet from its star,” he said.
The study suggests that all the planets in our Solar System were created from ice grains and carbon dust that orbit the young stars in the Milky Way.
Because water molecules are ubiquitous in our galaxy, one result of this “stone accumulation” theory is that planets with the same amount of water and carbon as Earth can be common around other stars in the galaxy. we have a galaxy.
Temperature is just as important for any planet that may resemble Earth. Only a planet located between the very close “fire line” and the distant “ice line” in a star system holds meltwater at its surface. That’s what the hunters of Earth 2.0 call a star “residence zone”.
The model also suggests that other planets with similar temperatures to Earth could have not only the same amount of water and oceans as Earth, but also the same number of continents as Earth.
That’s important because an ocean world isn’t 100% as likely to produce an intelligent life. “A planet covered in water would, of course, be good for sea creatures, but it would take a lower position than it would be suitable for creating civilizations that look at the Universe,” Johansen said.
It is hoped that the next generation of space telescope – such as the James Webb Space Telescope – will be able to take a closer look at exoplanets. Webb will be able to detect the presence of a water valve in an exoplanet atmosphere.
“It can tell us something about the number of oceans on that planet,” Johansen said.
Future ideas will test this model, but the theory that all planets receive the same amount of water is interesting for anyone interested in finding life beyond Earth. .
