Utmost life beyond the earth -

Radioactive waste eating bacteria, scorching heat and acid tolerating microbes in drastically dead zones on the earth endorse extraterrestrial life possibilities in the extreme environments of the solar system. Here you will know about such mysterious extremophile lives on earth, and our utmost planetary system locations indicating bio-signatures of the aliens.

Recently, an astronomy based episode of the famous TV show “Brahmand” (Universe) on the channel "Discovery" changed my entire perception about inhabitable Goldilocks zones on earth.
The program host Phil Plait, famous astronomer of NASA introduced its two more utmost life hunter scientists "Richard Hoover and Elena Pikuta" that found a new microorganisms species "Tindallia californiensis" in the extreme uninhabitable environment of California’s Mono Lake.
To know details, I researched more and found very interesting information about the few microbes nurturing at some unbelievable hostile areas of the earth.

Bizarre environments where the life has been found on earth

Since last few decades our knowledge about Goldilocks habitable zone on earth has been expanded. Earlier, the exo-biologists might have not considered entire earth as inhabitable, but now the life have been zoomed out even in severely chilled/lead melting water to the strongly acidic regions. Let us take a look over such locations:

Life without sunlight and life taking chilled environment

Promising evidence for Aliens on earth
Bizzare fish in Antarctic region thrives below thick ice layers without sunlight
Since centuries, sun is considered to be the prime source of life on earth. But the discovery of undersea ecosystem thriving in the complete darkness has given a wider amplitude to the biologists. Moreover, a colony of bizarre Antarctic fish below 2,500 feet of ice in no sunlight, deep chilled area is an added instance. 

Microorganism in California’s exotic Mono Lake

In the alkaline and excessively salty water (three times than sea) with pH of 10, the Mono Lake thrives "extremophiles" microbes and planktons
Even the bigger life (man and fish) could not survive in such environment. Besides this, lake’s dense mud (out the reach of oxygen) is also nurturing a new bacteria species – "Spirochaeta Americana".

Sterilized, space radiation bearing life

Another organism sustains life even in the most shocking conditions is - Deinococcus radiodurans bacterium, cable to challenge acid bath, food sterilization tests and dangerous space hazardous radiations. The bacteria found in the elephant dung and the cow patties.  
In future, its genetically altered clone expected to be used for making astronauts medicines, and for altering Mars environment for humans.

Microbes in the Mexican caves crystals

Geologists found a wide range of new species living inside the giant crystals in Maxican caves that was entirely isolated for over 60,000 years from rest of the life orienting environment (including oxygen). 

Extreme locations where life expected in the Solar system

Recently discovered bacteria "Solibacillus Kalamii"whose name is dedicated to India's former president and ISRO scientist "Dr. Abdul Kalam", is found in the International Space Station (400 kilometers away from the Earth). Remarkably, this no species of this bacteria has not been reported to be found on the earth, up to now.

After getting above promising proof of microbe bacterium in hellish nuclear reactors, lead melting hot water, chilling poles and stiff acids, let us step ahead towards similar extreme environments beyond the earth to search the life elsewhere: 

In sealed gas filled caves of Mars

The images received from the spacecraft orbiting the planet Mars confirm sealed caves on its surface. Such places on Mars are the perfect locations where Maxican caves like microbes could still survive without sunlight. And regarding their origin, the photographs from NASA rover have already confirmed the sings of ancient microbes on the planet.
Billions of years ago, while the planet was losing its atmosphere, microbes took shelter in such cave could still be survived out there. 

On comet and meteors

Since comet or meteors are considered to be the mysterious life carriers to the earth, thus such celestial objects can still be the life harbingers for others. European space agency’s Rosetta probe soft landing on P67 comet is one of such maneuvers for life finding missions. 

On Jupiter moon Europa

Europa is a large ice covered body orbiting the largest planet Jupiter. The astronomers are planning a future probe that shall pierce through its outer frozen, solid thick ice layer to travel inside flowing water. The flowing water closer to its inner surface expected to have bio signatures identical to Antarctic region’s microbes. 
The Presence of water on this distant celestial body, even outside the influence of sun, is possible due to the constant tidal pull/push effects of Jupiter’s gravitation force and nearby moons. 

Saturn moon Enceladus 

The latest NASA’s Cassini spacecraft mission reports the tiger stripe on the south pole of Saturn’s Enceladus moon erupting more than hundred geysers of water ice and other materials. Such reactions occur under the influence of H2 (hydrogen molecules). The astrology-experts believe it as the reaction of rocks with the hot water in the beneath sea surface of the moon.

Conclusion

"Life finds the way to sustain itself". The earth has already experienced several disasters like ice ages and meteor impacts in past, wiped the life out entirely, but the life is still here. 
Likewise, somehow if the life would have found the path to any solar body - Mars, Enceladus, Europa, or more in past, might have adapt there's harsh environment. The above compelling arguments provide clues that we are not alone in the universe, and need to find our solar system companions.  
Like ISRO’s cheapest and successful interplanetary Mars orbital Mangalyaan mission, we just need to find the ways to make our far off life exploring missions least expensive and time consuming. If you found above information interesting, do share it with your friends.
