03:19 PM Monday 19 June 2023 Researchers and scientists from the Center for Stars and Planets Formation at the University of Copenhagen, Denmark, put forward a new theory regarding the origin of water on Earth, and they said that our planet was absorbing water from the space environment surrounding it. The previous perception was that water reached Earth by comets The new theory put forward by the team suggests that regarding 4.5 billion years ago, when the sun was a baby star surrounded by a disk of gas and dust, the Earth was in the form of a primitive planetary disk, absorbing particles of dust and ice. “This process contributes to the presence of water,” says team member Isaac Onyet. During the formation of the Earth, instead of waiting for the arrival of ice comets to deliver water following 100 million years. And it gradually increases in size over 100 million years. In this scenario, the presence of water on Earth would need some kind of serendipitous event. “If this is how the Earth was formed, then we are lucky that we have water on Earth..and that It makes the chances of water existing on planets outside our solar system very low,” according to Science Alert. The team came up with their new theory by using silicon isotopes as a metric to measure the mechanisms of planet formation and the time scales involved. By examining the isotopic composition of more than 60 meteorites and planetary bodies, researchers have been able to establish a connection between rocky planets like Earth and other bodies in the solar system. The other has plenty of water. “This theory predicts that whenever you form a planet like Earth, you will have water on it,” said Martin Pizarro, a team member and Globe Institute professor. “If you go to another planetary system where there is a planet orbiting a sun-sized star, it should have The planet is on the water if it is at a suitable distance.
