According to Lauretta, the findings show that comets experienced processes such as heating and chemical reasons in liquid water
that changed the minerals they inherited from the time when the solar system still was a protoplanetary disk, a swirling mix of hot gases and dust, before it cooled dawn enough for planets to form.
Vapor from the plume contained two chemicals that hint at an ocean of liquid water
beneath Enceladus's surface.
Yet, it is the nature of liquid water
which has largely captivated the interest of physical chemists.
Scientists believe they may have discovered the first liquid water
outside of the Earth, in the form of vast lakes under the icy surface of one of Jupiter's moons.
Ancient regions on Mars bear signs of abundant water -- such as features resembling valleys carved by rivers and mineral deposits that only form in the presence of liquid water
Recently, researchers using NASA's Mars Reconnaissance Orbiter observed the seasonal appearance of hydrated salts indicating briny liquid water
Currently, the search for planets that could sustain liquid water
on its surface, and therefore life, is limited to planets within its host star's habitable zone.
And where there is liquid water
, there could also be life.
The first reports of formative gullies on Mars in 2000 suggested the presence of liquid water
on the Red Planet, the eroding action of which forms gullies here on Earth.
Past experiments had detected liquid water
at -38[degrees]C but not colder, despite scientists' suspicion that it could subsist for measurable periods of time at even lower temperatures.
WASHINGTON, Sept 28 (KUNA) -- NASA announced on Monday that it has "strong evidence" that liquid water
exists on Mars, this discovery supports speculation that life may exist on the planet.

is responsible for mysterious <B features on the planet that change with the seasons
