NASA announced a place that could exist in the solar system

According to experts, Saturn's moon, Enceladus, officially joins places where life is likely to exist right in the solar system.

NASA press conference took place at 14h EDT Thursday, April 13, 2017 (ie 1am on April 14, 2017 Vietnam time) gave us interesting information about a place that could exist. life in the Solar System.

NASA said there was a place where life could exist in the Solar System.

Before the press conference took place, NASA spokesperson shared: "These are important findings for this future ocean exploration mission - including NASA's post-2020 Europa Mission mission - and publicity. the search for life outside the Earth in the far future ".

We know that 4 conditions are needed and enough for life to be water, necessary chemicals, a source of energy and enough time for life to grow.

Enceladus - The moon of Saturn, where there is a possibility of life.

Fortunately, Enceladus - Saturn's moon - Saturn's sixth largest satellite has possessed up to three elements and it officially joins places that are likely to exist in the solar system.

Enceladus is said to be a potential candidate for life.

According to the press conference, Cassini probe on Saturn has collected important evidence, showing that life can grow right in our solar system.

Cassini has been approaching Saturn's orbit since 2004 and has found many interesting things, such as liquid methane on Saturn's Titan moon.

And now, it also detects chemical reactions and hydrothermal reactions on Enceladus - the reactions needed to create an environment that allows microorganisms to survive and grow.

Scientists found that there were many chemical reactions and hydrothermal reactions on Enceladus.

Chemical reactions and hydrothermal reactions on Enceladus are needed to create an environment that allows microorganisms to survive and grow.

This is like a missing piece to prove life survives on Enceladus. It has turned the small satellite 887 million miles away from the Sun into a bright candidate to allow life in the solar system, like Mars and the moon of Jupiter.

According to Professor David Rothery of Open University: "The only life we ​​know today is us. But if life can grow at Enceladus, that means that out of billions and billions of planets and planets. out there, there must be life. "

Earlier, NASA knew that beneath Enceladus' ice surface there was liquid water . And to discover this huge ocean, experts must rely on cracks that are releasing a bunch of matter onto the surface of the satellite.

As a result, they confirmed 1.4% of the released materials are hydrogen molecules - thought to be the product of the same hydrothermal reaction on Earth.

1.4% of the released matter is hydrogen molecules thought to be the product of the same hydrothermal reaction on Earth .

In addition, 0.8% of them have CO ₂ , and along with hydrogen, these are the chemicals needed for bacteria to make methane - which Earth's ocean-bottom bacteria create.

Professor Hunter Waite - head of the Cassini Ion and Neutral Mass research group at the Southwest Research Institute (SwRI) in San Antonio shared: "Enceladus has an ocean beneath the ice. There are cracks on the ice and objects. Substance that flows out of the material shows signs of chemicals that are often present in reactions between the ocean and hard rock surfaces.

We realize that hydrothermal reactions are taking place here. That said, geochemical reactions can help life prosper, even when there is no light. "

And that life here - if it exists - will have a single-celled, single-celled form, like in the hydrothermal tubes of our Earth's oceans. These forms of life do not need oxygen nor need sunlight.

This finding does not clearly state that life exists on Enceladus.

They may even have been like life on Earth, before harsh conditions forced them to change.

However, this finding does not clearly confirm that life exists on Enceladus. But this is a huge step forward to prove it.

According to Dr. David Clements, astrophysicist at Imperial College London: "It is great to confirm the existence of hydrothermal reactions in a different place from the Earth, in the Solar System itself." Anyway, this discovery is the greatest feat Cassini has ever made, especially when the $ 3.3 billion probe has entered its last month of activity.

NASA had a plan to crash Cassini into Saturn's surface, and was supposed to protect Enceladus. They are forced to do so, because the ship is at risk of causing Enceladus to infect the Earth, and if that happens, we will not prove anything.
