Shrimp Discovery 180 Meters Depth Life in Antarctic Ice

Previously alleged that under a layer of ice as thick as 600 feet (180 meters) and in the absence of sunlight there is no life other than microbes only just turned out wrong. A group of NASA scientists discover animals from the family of crustaceans and jellyfish live under a thick layer of ice in Antarctica. Surprising discovery that started when they lowered a camera down through the Antarctic ice sheet, and without them guess the camera caught shrimp-like animal movement approaching toward the camera and attached to the camera cable. Besides shrimp, the scientists also discovered traces of which probably came from the tentacles of jellyfish.

"At first we assumed there was no (animal) anything down there," said NASA scientist Robert Bindschadler, who presented the findings following the videotape, on Wednesday (17/03/2010) at the American Geophysical Union meeting. Animals with a length of 3 inches it was recorded by the camera about two minutes. Shrimp-like animals that is precisely Lyssianasid Amphipod, not shrimp, but had a relationship with the family crustaceans. Of course this invention is not trivial because the discovery would challenge the thinking about a minimum requirement to living organisms. If there is a type of shrimp that can live under a layer of ice 180 meters thick, why is not possible if there are organisms that also live on the moon planet Jupiter, Europa is covered with ice it?

Microbiologists Cynan Ellis-Evans of the UK Antarctic survey agencies also dumbfounded by this discovery. "This discovery (animal), first on the environment under a layer of ice which is a complex organism." He also explained that previously had found similar things in the area of ​​the ice sheet began to melt, but there has never been the discovery that just below the ice. But he also stated that the animal might have swum so far and get lost in there, so the area is not their permanent habitat.

But Kim, one of the scientists involved in the discovery were dubious allegations of 'lost animal' it. The location of the discovery that more than 19 km away from the open ocean.

Bindschadler and his team just drill a hole diameter of approximately 20 cm and only observe a very small waters. That is, it is probable that there are two organisms that swim that far and then trapped in the narrow waters.

Indeed, scientists are still puzzled what the animal food sources. According to Kim, if microbes could produce its own food from chemicals in the ocean, but complex animals like Amphipod it can not. ref: kompas

Ice sheets in Greenland and Antarctica Melting 3 Times Faster

NASA has recently revealed its findings about the melting ice in Greenland and Antarctica that was three times faster than previously anticipated. Quoted from Physorg site, where the research using satellite imagery found that ice sheets in Greenland and Antarctica have been losing mass as much as 475 gigatons each year in which the volume will result in world sea levels rise an average of 1.3 millimeters / year. "sea level rise is more dominated by a layer of ice over the glacier is not too surprising, since winning the ice layer of ice that contain more" said Eric Rignot, a joint research between NASA's Jet Propulsion Laboratory with the University of California. But he added that if this is allowed to continue to occur then the sea levels will rise significantly from that which had been predicted earlier by the United Nations Intergovernmental Panel on Climate Change at 2017.

green pool at the south pole

green pool at the south pole - At the south pole there is a pond filled with life, surrounded by white ice, but water in the pond is green, looks striking in the appeal in the surrounding waters. The green color is actually derived from chlorophyll from algae is widely available there. According to Patricia Yager, chief scientist Amundsen Sea Polynya International Research Expedition (ASPIRE), chlorophyll content per liter of water in the pool is five times as much on appeal
my water taken from several places around the Amazon river. Such waters according to Yager usually rich in nutrients, so many kinds of animals that live there. Back According to Yager, the growth of algae which is very much of this could be a boon because algae absorb carbon dioxide as the greenhouse effect. But the next effect is that if the algae growth surged, the zooplankton will also be increased because the natural algae are food for zooplankton. With the number of zooplankton, the carbon dioxide will also increase as the effects of breathing Zooplankton process that releases carbon dioxide into the atmosphere.

NASA scientists discover an alien bacteria

NASA scientists discover an alien bacteria. As news reports on CBSNews.com (6 / 3) that a scientist of NASA (National Aeronautics and Space Administration) wrote a paper in the Journal of Cosmology edition of March 2011, it reveals the results of lab tests he conducted on the CI1 meteorites called Meteorite Carbonaceous which indicates the presence of bacteria in the meteorite is believed to date from the original regional meteor.
 

"Filaments complex found in the CI1 Carbonaceous meteorites showed no bacterial microfossil 'natives' of cyanobacteria," Hoover said in his writings.
 

In his paper, Hoover concluded that with Cyanobacteria that he found it shows the existence of extraterrestrial life. With Hoover's conclusions are of course also strengthen the opinion regarding the existence of living beings outside the earth, although this conclusion also raises the pros and cons among scientists and is still a matter of debate.
