A recent discovery suggests that Earth's water may have come from icy celestial bodies that bombarded the planet during a dramatic period about four billion years ago. This cataclysm was influenced by shifts in the orbits of gas giants like Jupiter and Saturn, which sent asteroids and comets towards the inner solar system. A team of astronomers has now confirmed the presence of crystalline water ice in a young star system, HD 181327, through NASA's James Webb Space Telescope, indicating that similar processes could happen throughout the universe.
Astronomers believe that much of our planet's water originated from icy celestial bodies that struck Earth during a massive bombardment triggered by shifting planets.
This remarkable discovery of crystalline water ice in the debris disk of HD 181327 provides crucial evidence that our solar system's formation is not unique.
