Everyone knows the importance of water on planet earth; no
one can survive without water. So water was a vital source to increase the life
on Earth and also imperative to evaluating the possibility of life on other
planets. However to identifying the original source of Earth’s water is important
to understanding how life-fostering environments come into being and how unlikely
they’re to be found elsewhere. New work from a team, including Carnegie’s Conel
Alexander, observed that plenty of our solar system’s water perhaps originated
as ices that formed in interstellar space. However; water is found throughout
our solar system, not just on Earth, but on icy comets and moons and in the
shadowed basins of Mercury. Thus water has been found included in mineral
samples from meteorites, the Moon, and Mars.
Comets and asteroids in specific, being basic objects, deliver
a natural “time capsule” of the conditions during the early days of our solar
system. Their ices can tell experts regarding the ice that encircled the Sun
after its birth, the origin of which was an unanswered question until now. In
its youth, the Sun was surrounded by a proto-planetary disk, the so-called
solar nebula, from which the planets were born. But it was unclear to scientists
whether the ice in this disk created from the Sun’s own parental interstellar
molecular cloud, from which it was created, or whether this interstellar water
had been damaged and was recreated by the chemical reactions taking place in
the solar nebula.
