Subj: Water Among Stars/1
Hello everyone :
I thought I would share a report from a local paper which copied a wire
from Seattle Times reporter Bill Dietrich about star explosions creating
water in space.

VIOLENT EXPLOSION OF STARS CREATES WATER IN SPACE
By: Bill Dietrich, Seattle Times
It's wet up there. Not just in the leaden skies, but in interstellar space.
Astronomers used an infrared satellite launched by the European Space
Agency last year to analyze the content of the dust between the stars and
found water, both as ice and vapor.
That discovery is helping break down the boundaries between the rich
chemistry of Earth and the near-emptiness of space. Scientists have
discovered not only water between the stars but vinegar (acetic acid),
methyl alcohol, carbon monoxide, ammonia, and polyaromatic hydrocarbons,
the carcinogenic PAH crust that can also turn up on barbecued meat.
The picture presented at June's American Astronomical Society meeting
was not the cold, static cosmos the sky appears to the naked eye but
rather a violent, gorgeous and cyclic stellar ecosystem in which dying,
exploding stars create the elements and compounds that later show up on
planets, comets and astroids.
Earth and our own bodies are the ultimate recycling triumph: Our atoms
are the product of the exploding fires of old stars. And we drift,
astronomers said, through vast clouds of interstellar dust containing
many of the basic chemical building blocks of life.
"The whole cycle is now complete with regard to water," said astronomer
Thijs de Graauw of the Netherlands. The chemical reaction of an exploding
star creates oxygen and combines it with hydrogen to make water, and then
this water cools hot gases sufficiently to allow them to coalesce into
new stars.
"Stars form by the collapse of a cloud of gas and dust, but a buildup
of heat inside the cloud makes the work of gravity harder, when it tries
to compress the cloud," explains Ewine van Dishoeck, another Dutch
astronomer. "Water enables the cloud to shed heat very efficiently. This
facilitates star formation.
Earthlings got a firsthand look at water from space in March when the
comet Hyakutake, a "dirty snowball" with a diameter now estimated at
about three miles, came within 9 million miles of Earth and put on the
brightest comet show in 20 years.
Astronomer Jean-Loup Bertaux of France has calculated that Hyakutake
burned off 3 tons of water per second as it neared Earth and that the
weight loss rose to 10 tons per second as the comet whipped around the
sun. In all, Hyalutake spewed 100 million tons of vapor into space and
lost about a tenth of a cubic kilometer of it's mass during the time it
spent in the sun's inner solar system, Bertyaux calculated.
In other words, he said, the comet was losing more than enough water to
satisfy the needs of Madison, Wis., a city of about 200,000 people.
Astronomers believe billions of such comets form a cloud around our
solar system, a few of them jostled and falling inward toward the sun
when a passing star disturbs their orbit.
And Bertaux said crashing comets may have been the source of much of
the water on Earth. Although the Earth may have coalesced from space
debris that included water, much of this might have been lost if our
planet collided with another in a smashup that is believed to have
formed the moon. Comets "may have been a major source" of water
replacement, the astronomer told reporters.
Close-up examination of comet Hyakutake has revealed a much more
complex visitor than the tadpole shaped nucleus and tail usually
sketched. Hydrogen from the comet formed a cloud 10 million miles across
during it's visit. Water evaporation on the side of the snowball facing
the sun created jets of vapor that swirled sunward like the arcs of a
sprinkler. A piece of snowball 600 feet in diameter broke off and
followed in one of three different tails that formed of different
materials.
In other words, the more astronomers peer into space, the more
intriguingly complex it becomes. There is a flood of discovery right
now, triggered by technology.
