Aquatic Planets are Common in Our Milky Way Galaxy, Study Suggests | Astronomy, Planetary Science - Sci-News.com

“All our data suggest that water was part of Earth’s building blocks, right from the beginning,” said Professor Anders Johansen, a researcher in the Centre for Star and Planet Formation at the University of Copenhagen and Lund Observatory.

Using a computer model, Professor Johansen and colleagues calculated how quickly planets are formed, and from which building blocks.

“The water molecule is found everywhere in our Galaxy, and that the theory therefore opens up the possibility that other planets may have been formed in the same way as Earth, Mars and Venus,” Professor Johansen said.

“All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon as Earth — and thus potential places where life may be present — occur frequently around other stars in our Galaxy, provided the temperature is right.”.
