Hang onto your chair and prepare to have your mind blown.. New research reveals that a big portion of the Earth’s water is older than previously thought, and actually predates the age of the Sun.
Moreover, the findings of the study
suggest that water – and life – could exist on exoplanets throughout our galaxy and beyond.
That bottle of water sitting on your desk is really really old.. Actually, unfathomably ancient..
“This is an important step forward in our quest to find out if life exists on other planets,” said Professor Tim Harries of the University of Exeter, a member of the research team. “We know that water is vital for the evolution of life on Earth, but it was possible that the Earth’s water originated in the specific conditions of the early solar system, and that those circumstances might occur infrequently elsewhere.”
The findings increase the chances that water is present on other planets. The study confirms that the way in which our solar system was formed is not unique, which means that the same conditions – and therefore life – likely exists elsewhere in our galaxy.
It is an amazing finding, given the fact that approximately 2,000exoplanets
have been discovered so far, and no one knows how many of them may still be waiting to be discovered. According to the estimations, each star in the Milky Way galaxy hosts at least one planet.
It is worth noting that water is not an exclusive privilege of our planet. In fact, much evidence of it can be found throughout our solar system. In particular, water ice is present on comets and asteroids, as well as on other planets of our solar system and their moons, such as Jupiter’s Europa or Saturn’s Enceladus.
The prevailing theory in modern cosmology suggests that water came from the solar nebula
, or the so-called protoplanetary disc
, a cloud of dust and gas surrounding the forming Sun. Now, researchers from the University of Michigan
led by astronomy PhD student Ilse Cleeves decided
to find out whether the water was already present in the sun’s protoplanetary disc, or whether it was formed with the birth of the Solar System.
