Extremophiles I Have Known And Loved

Extremophiles challenge everything we thought we knew about the beingness of life on Earth . Now , astrobiologists are question if some extremophiles are really extraterrestrial living among us . Just who are these incredible puppet , and what can we learn from them ?

Extremophiles are organisms that prosper in the most extreme environments on Earth . From the sulphuric hot springs in Yellowstone National Park to the frosty Antarctic , these creatures press the terminal point of what we know about biology , and force us to reevaluate the possible action of extraterrestrial life soma . scientist are finding an ever - increasing turn of these tough fiddling organisms living quite happily in places where we antecedently think no liveliness could possibly exist . Extremophiles have even been find nestled in the meat of a nuclear reactor .

The Chernobyl funguswas discovered several years ago , when scientists were using an R.O.V. to inspect the Chernobyl site . To their surprisal , they found a glowering sludge on the walls , living within the nuclear reactor and in reality feeding on the radiation . The melanin - rich fungus increases rapidly in sizing when exposed to a high-pitched grade of da Gamma rays ( and no , you would n’t like it when it ’s angry ) . Other fungus kingdom and bacterium have been discovered with the same power to thrive within radioactive environments . Deinococcus radiodurans , an amazing polyextremophile with the preeminence of being consider the humans ’s most durable bacterium , is capable of withstanding 5,000 Grays of radiation ( 500,000 rads ) . The breakthrough of such fungus kingdom and bacterium have furnish scientist with a spectacular breakthrough in finding constituent ways in which todetoxify radioactive waste .

Extremophiles are not just microbes ; more highly evolved puppet have also proved to be as lasting , and as strange and wonderful , as the Deinococcus radiodurans bacteria .

The Pompeii Worm

This extremophile keeps a cool head even in utmost temperature . The Pompeii Worm finds a home ground on or near Black Smokers , hydrothermal vents on the sea story , which give the worm its volcanic name . Nestled within its cozy subway system , its body stays at a very toasty 175º F , while its plume - corresponding head protrudes from the tube into water that is a much more temperate 72º F. Weirder still , its fleecy coating is really a colony of bacterium that lives in a symbiotic relationship with the insect , feed by mucus secernment produced by the worm . really an queerness , the Pompeii worm ( and its sustenance coat ) obviously has a lot to teach us about living in an uttermost cooking stove of temperatures .

The Tardigrade

The Tardigrade is considered the king of the extremophiles . These microscopical being wait like clear gummi bears come to life ( hence their more common name , “ Water Bears ” ) and have rise to be more long-wearing than Twinkies . Tardigrades have been discovered all over the world , and in the most astonishing place , from the peaks of the Himalayas to the ocean base , from temperature border on inviolable zero to temperatures over 303 ° F.

Like the Chernobyl fungus , these marvelous Water Bears can withstand venereal disease of gamma rays deadly to homo without shrink . Tardigrades can also withstand the extreme pressure of a vacuum , andresearch is being conductedto trial Tardigrades ’ strength in space . The Tardigrade Space programme has been geekily nicknamed … yes , you guessed it … TARDIS .

NASA astrobiologistRichard Hooveris leading the hunt for more extremophiles , hoping to try out that some of these little fellas are not of our human beings , but interstellar encumbrance - hikers that do here million of years ago on meteors . The existence of organisms like Deinococcus radiodurans and the Tardigrades gives weight to the statement that some of these extremophile lifeforms are actually extraterrestrial being among us . If these creatures can exist in the emptiness of space and withstand such high levels of radiation , then it is just potential that these abilities are evolutionary trait that enable them to go far here , on Earth , from somewhere else in the extragalactic nebula .
