Telescope Spots a Star Spewing Powerful Water Jets into Interstellar Space

A Protostar and its Polar Jets NASA/Caltech
Researchers looking for signs of life elsewhere in the universe often start by looking for one key ingredient necessary to complex life as we know it: water. And just 750 light-years away, they’ve found quite a bit of it spewing from the poles of a young, sunlike star that is blasting jets of H2O into interstellar space at 124,000 miles per hour.

This discovery is interesting on a number of levels. For one, it indicates that throughout the universe young protostars could be distributing vast quantities of water, potentially seeding life elsewhere. But it also sheds some light on the formation of our own sun, and the role water may have played in its formation and in the formation of our own planet.

The star was discovered by ESA’s Herschel Space Observatory, whose eyes were able to pierce the dense cloud of gas and dust that is feeding the star’s formation. There, Herschel saw light signature indicative of hydrogen and oxygen, and in following those traces found that these atoms are forming water on and around the star. But as the molecules move through the star and are injected into the massive jets of gas spewing from the poles, the heat and pressure vaporize the water into jets of gas.

Only when the gas jets are far enough away from the star do they rapidly cool and turn back into liquid. At this point, the water droplets are essentially bullets of water moving something like 80 times faster than the average round fired from a rifle. And there’s a lot of them. The amount of water ejecting from the star is equal to the amount that flows through the Amazon every second, researchers say.

2. Forming an Oort cloud?

Future comet creation?

Interesting, I don't remember ever seeing direct evidence of water formation before.

3. And thus are comets formed.

Cool.

4. I remember reading an article stating that earth receives water from outer space -

can't remember where I read that article. Interesting...
