NASA Antarctica Discovery Might Foreshadow Potential Extraterrestrial Life Forms

82586042

A 2009 discovery at the bottom of the world could have implications on the search for extraterrestrial life. NASA researchers were astounded to find an amphipod swimming beneath a massive Ross Ice Shelf, about 12.5 miles away from open water. NASA scientists were using a borehole camera to look back up towards the ice surface when they spotted this pinkish-orange creature swimming 600 feet below the ice, where the NASA team expected to find no higher life form than some microbes.

The image below provided by NASA, taken in Dec. 2009, shows a Lyssianasid amphipod, which is related to a shrimp, where a NASA team lowered a video camera to get the first long look at the underbelly of an ice sheet and a curious shrimp-like creature came swimming by and then even parked itself on the cable attached to the camera. In a surprising discovery that shakes the idea of where higher life can thrive, scientists for the first time found a shrimp-like creature and a jellyfish frolicking beneath a massive Antarctic ice sheet.

About 150 new types of fish were among 500 new marine species, including furry crabs and a lobster off Madagascar, found in the seas in 2006, according to researchers in the 70-nation Census of Marine Life.

Many species were found in places long thought too hostile for life -- including by a vent spewing liquids at 407 Celsius (764.6F) and other habitats that were as inhospitable as planets such as Mars or Venus.

"The age of discovery is not over," said Jesse Ausubel, a program manager at the U.S. Sloan Foundation which is a sponsor of the 10-year Census. Finds "are provocative for NASA and for people who are interested in life in places other than Earth."

Among discoveries in 2006 were shrimps, clams and bacteria living by the searing 407C vent on the floor of the Atlantic Ocean north of Ascension Island, the hottest sea vent ever documented and more than hot enough to melt lead.

"This is the most extreme environment and there is plenty of life around it," said Chris German, of Britain's Southampton Oceanography Center and a leader of the Atlantic survey.

He said one big puzzle was how creatures coped with shifts in temperatures -- water on the seabed at 3,000 meters (9,842 ft) was just 2C yet many creatures withstood near-boiling temperatures of up to 80C from the thermal vent.

1021208952_942c7c89a2 Researchers had not yet probed how hardy the microbes nearest the hottest part of the vent were -- a type of bacteria called "Strain 121" found in the Pacific in 2003 holds the record by being able to withstand temperatures of 121 Celsius. Another expedition found crustaceans, jellyfish and single-celled animals living in darkness in the Weddell Sea off Antarctica under ice 700 meters thick and 200 km (125 miles) from open water.

"You can think of it as a cave, one of the remotest caves on earth," Ausubel said of findings by a robot camera."Wherever we've gone on earth we've continued to find life," German said. He said recent discoveries could be encouraging for the search for life elsewhere in the universe.

Astronomers speculate that Jupiter's moon Europa could hide an ocean beneath its frozen surface and Ausubel noted life has been found on Earth beside subsea methane seeps -- Saturn's moon Titan also has methane. And NASA said last week it had found signs of liquid water on Mars.

Among other 2006 finds by the census, due for completion in 2010, was a "Jurassic shrimp" in the Coral Sea east of Australia and previously thought extinct 50 million years ago.

Very cool! it will be exciting to see what they find in the waters of Lake Vostok, 2.5 miles beneath the Antarctic ice too!

As far as the little amphipod mentioned above goes, here's a video of it appearing on camera: http://vodpod.com/watch/3263350-surprise-shrimp-found-below-antarctic-ice

Life exits every millimeter of space on Earth, and more in the distant universe because we are ONE with Him.

Incredible discovery. Just goes to show how adaptive life is. It certainly does lend hope to the notion of life on other planets.

OK this makes a lot of sesen dude.

incredible discovery? That is lame. Ignorant. We know nothing. Humanity guesses.

Oh, oil, money, suppression, NOW we got the human`s attention.

The world is a beautiful place. Of course there is life everywhere.

Unfortunately I have to add "Where we do not kill them"

One virus on earth. It is modern man.

CRAB PEOPLE!!

Extraterrestrial Life-Forms Found In Ice Meteorite

Sometimes I wonder why scientists think so narrowly about the term "life" when DNA has shown incredibly adaptive over and over again. Life can probably form in any environment imaginable, given the right conditions.

The blogs on this site are really well done, but I would like to see the sources of your information so I can read more in depth about the subjects.

We will get lots of info of the life forms that are there over there. This will be a landmark discovery and all those who have interest in knowing those things will truly feel satisfied.

Let us wait for more on this.
