Scientists, exploring the origins of water on Earth and other exoplanets, may have uncovered a promising hypothesis with the assistance of the
The groundbreaking revelation stems from observations of four young stars surrounded protoplanetary disks — dense gas discs encircling newly formed stars. The
This finding challenges the notion that the inner and outer regions of a solar system are isolated, supporting the ice-covered pebble theory as a more plausible explanation for Earth’s water origin.
Contrary to the long-standing belief that Earth’s water arrived from icy comets and asteroids after its formation, this new hypothesis posits that water originated from ice-covered pebbles drifting inward from the outer Solar System. The James Webb telescope’s recent breakthrough is anticipated to conclusively elucidate the source of Earth’s water.
Additionally, this discovery holds significance for the quest for extraterrestrial life, suggesting that the delivery of water to planets is more common than previously believed, thereincreasing the likelihood of finding life on other planets.
