Life has survived and even flourished in the Earth's most inhospitable environment. And because of this, researchers are increasingly convinced that aqueous worlds reminiscent of Earth are the best candidates to search for alien life. Dr. Amanda Hendrix, co-chair of NASA Roadmaps for Ocean's World Group, told Express.co.uk: "Ocean worlds can represent the best opportunity in our solar system to find life."
"We must understand whether these oceans are habitable and, if so, whether these oceans are actually hosting life."
NASA has now announced plans to burn a groundbreaking probe to Neptune's frozen moon Triton.
This is because many scientists believe that Triton stores a sea hidden under the icy exterior.
Water is an important ingredient necessary for life, which means that if Triton has a sea, it can be the home of small alien life forms.
NASA Jet Propulsion Laboratory researchers suggested plans to explore Triton by Lunar and Planeta

NASA Ocean World's mission would involve the development of a new kind of spacecraft k
Trident would fly to Triton to photograph the frozen moon and analyze the chemical makeup of the atmosphere for evidence of subterranean oceans.
And if water is found, the largest of Neptune's 13 moon will immediately become the number one target for future alien hunting missions.
Trident will also give researchers a chance to visit Neptune and its moons for the first time since the 1980s and explore an object from the Kuiper Belt.

The belt is a ring of icy lumps that are far beyond Neptune, and the researchers believe that Triton is a Kuiper object that got knocked into Neptune's gravity billions for years ago.
Dr. Hendrix added: "Triton shows tantalum hints of being active and having a sea.
" It's a three to one goal because you can visit Neptune's system, visit his interesting sea world and also visit a Kuiper belt object without should go all the way out there. "
Little is known about Triton, and the only pictures we have of the moon were captured by the Voyager 2 probe in 1989.

During this flyby, NASA researchers noticed triton spitting gnaws that spit out nitrogen gas.
The moon is believed to resemble Pluto in many ways and is the coldest known object in the solar system, with surface temperatures falling – 235 ° C.
This is two and a half times colder than the coolest temperature ever recorded on earth, a Soviet weather station in Antarctica in 1983.
