#Earth's Water Is Older Than The Sun Since water is one of the vital ingredients for life On earth scientists want to know how it got here.
One theory is that the water in our solar system was created in the chemical afterbirth of the Sun
. If that were the case it would suggest that water might only be common around certain stars that form in certain ways.#
#But a new study published today in Science suggests that at least some of Earth s water actually existed before the Sun was born
--and that it came from interstellar space.##That s certainly something to ponder the next time you drink a glass of water.#
#But the discovery is also cool because it means water --and maybe life#--may be ubiquitous throughout the galaxy.#
#If water in the early Solar system was inherited primarily as ice from interstellar space then it is likely that similar ices
along with the prebiotic organic matter that they contain are abundant in most or all protoplanetary disks around forming stars study author Conel Alexander explained in a press release.#
#The researchers concluded that a significant portion of Earth s water came from interstellar space by looking at the relative abundance of hydrogen and deuterium.#
Earthly water contains some deuterium too but in low quantities--up to 30 times less than interstellar water.
Looking at a water sample s ratio of hydrogen to deuterium can tell you about what conditions were like when the water formed.
Because of that the researchers estimate that anywhere between 7 and 50 percent of Earth s water had to have come from the interstellar medium in
And since other solar systems would have formed in the same interstellar medium the findings suggest that the origins of water On earth were not unique

The chemicals allow the water to remain liquid at lower temperatures but also help keep it from boiling off in the thin atmosphere of Mars,
It remains unclear where the water comes from. Theories include deliquescence, melting subsurface ice or even a liquid-water aquifer that feeds the process.

#Nasa Finds Liquid Water On Mars In a Mars-related press conference this morning NASA has announced that nder certain circumstancesliquid water has been found on Mars. ars is not the dry arid planet that we thought of in the past,
but scientists had thought the atmosphere of Mars was too thin for liquid water to be possible.
These streaks had been noticed to vary following temperature changes on the surface leading to a hypothesis that the substance was water.

NASA scientists said today enabling the liquid water to exist for longer before either freezing as the temperature on the planet drops,

#Signs of liquid water found on surface of Mars, scientists say Despite its reputation as a forebodingly dusty, desolate and lifeless place,
Scientists reported on Monday definitive signs of liquid water on the surface of present-day Mars,
"That's a direct detection of water in the form of hydration of salts,"Mcewen said."
"There pretty much has to have been liquid water recently present to produce the hydrated salt.""By"recently,"Mcewen said he meant"days, something of that order."
Scientists have known long that large amounts of water remain but frozen solid in the polar ice caps.
There have been fleeting hints of recent liquid water, like fresh-looking gullies, but none have proved convincing.
Scientists suspected that water played a critical role in the phenomenon, perhaps similar to the way concrete darkens when wet, with no change in the shape of the surface,
"It's very definitive there is some sort of liquid water, "Ojha said. The perchlorate salts lower the freezing temperature,
and the water remains liquid. The average temperature of Mars is about minus 70 degrees Fahrenheit,
For one, scientists do not know where the water is coming from.""There are two basic origins for the water:
from above or from below,"Mcewen said. The perchlorates could be acting like a sponge, absorbing moisture out of the air,
