Introduction to The search for life away from the earth:-

Life on Earth began about 3.7 billion years ago in the form of a single cell that gradually evolved from a single cell into a multicellular cell.
As far as we know, the diameter of the universe (observed universe) is 93 billion light winds (8.8E23 km). Hundreds of white dots will appear on a black background – each dot represents a supercluster – there are approximately 100 million super clusters in this universe, clusters and galaxy clusters. “
A typical galaxy cluster consists of more than 50 galaxies, with the galaxy cluster consisting of hundreds to thousands of galaxies.

The galaxy that is part of our solar system is called the Milky Way galaxy.
The Milky Way galaxy is located in the local group of galaxies. This group contains at least 50 galaxies. The Milky Way galaxy contains about 400 billion stars. It will take us 200,000 years to move from one end to the other at speed.

According to the 2013 Kepler space mission, the Milky Way galaxy contains 40 billion Earth-like planets, of which 11 billion revolve around habitable regions like the Sun.

Now you tell us how we can be alone in such a powerful temple universe – so we have the same status in this universe as a grain of sand in the vast desert or maybe even less – so don’t believe in space creatures. Doing this is like taking a spoon to draw water from the sea and saying that there are no sharks and whales in this sea because it would be wrong to say so if they do not come in my deaf water spoon.

In fact, our current technology is capable of finding life connected to Earth – when we think of life away from Earth, we immediately see in our minds an example of Earth-like life – life on Earth is based on carbon. Is. It needs three major components to make it thrive.

1-Water in liquid form – Water acts like a home delivery vehicle in the body of living beings to meet its need as it recognizes the essential nutrients in the cells – minerals, vitamins, glucose and other essential elements. In absorbing. Helping, removing waste products and maintaining body temperature.

2. Chemical elements – from bacteria to blue whales, every living thing is made up of these six major elements – carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur – thousands of atoms of these elements chemically react Express Large molecules come in a special order that forms a “cell”. This is equivalent to arranging a Rubik’s Cube in the same color. 3- Chemical energy – No living cell can survive without energy – Every living cell needs energy to survive, from which it can grow, repair, and regenerate. Helps to maintain, balance, move and protect oneself. Let’s first try to find life from our solar system – our solar system is like a big family in which the sun is the largest house and the rest of the bodies are members of the house.
   The solar system has a total of eight planets, three dwarf planets, about two hundred satellites or moons, and hundreds of other small celestial bodies. The possibility of life in the solar system can occur in the following places.

Climate change and our preparations

MARS

2. Mars is the fourth smallest planet in the solar system in terms of distance from the Sun and the second smallest planet after Mercury – it is also called the Red Planet because of its red color. This red color contains iron oxide on the surface of Mars. Due to the abundance of.
   In July 1965, the US Mariner 4 was the first spacecraft to pass so close to Mars – the first spacecraft to take such close-up images of another planet. Provide information about the Earth’s surface and atmosphere – all of these successful missions led us to the fact that billions of years ago there were three major components on Mars that were sufficient to sustain life. In 2013, NASA’s Curiosity rover mission discovered elements of life on Mars that are essential for life – such as carbon, hydrogen, nitrogen, oxygen, sulfur, phosphorus and some minerals. It is estimated that many years ago there would have been a freshwater lake or canal in which neutral acidity and low salinity levels indicate microbial life. The source of energy on Mars must have been a volcano.
   The atmosphere of Mars contains 93% carbon dioxide, which is why the surface of Mars is not suitable for any kind of life – so we cannot deny that if there is life on Mars, then there is no one on Mars. There was no life. It will be in the depths of the sea.
   The Italian Space Agency (ASI) published an article in July 2018 stating that their mission’s radar Mars used a spacecraft to detect a lake of water 1.5 km below the ice cap at the South Pole of Mars. Used powerful beams. We need to start more missions to learn more about Mars.

EUROPA

2. Europa The smallest of Galilean’s four moons orbiting Jupiter is called Europa. And this is the sixth closest moon to Jupiter. It is also the sixth largest moon in our solar system. Water is at the forefront of life-sustaining ingredients because water helps cells identify essential nutrients and spread pollution – scientists say Europe may have water derived from seawater found on Earth. Be done The surface of Europa is rocky ocean. It can be said that rocky sea level.

And this is the sixth closest moon to Jupiter. It is also the sixth largest moon in our solar system. Water is at the forefront of life-sustaining ingredients because water helps cells identify essential nutrients and spread pollution – scientists say Europe may have water derived from seawater found on Earth. Be done The surface of Europa is rocky ocean. It can be said that rocky sea level.

When seawater is formed in the middle of seawater, chemical nutrients are formed which are being used by living beings for food. will be done.
Europa is an ocean, as evidenced by NASA’s Galileo spacecraft – which orbited Jupiter from 1995 to 2003, during which it made 12 orbits around Europa. The magnetic field in Europe is actually being created by Jupiter’s powerful magnetic field and the salty sea of ​​Europe.
This means that the roof needed for aerial life in Europe exists in the form of a magnetic field.
The formation of Europa’s upper surface indicates that there is an ocean beneath it – images from Galileo and other spacecraft show that the number of meteor galaxies in Europe is smaller than in other solar systems. One of the reasons for this may be the moon, because geologically European activities are still going on in Europe, due to which the old pits may have been mostly erased or they may have been covered with a blanket of ice. Is gone Not happening – the surface of this Galilean moon looks like smooth and shiny thin ice. This type of icy structure you will find on the continent of Antarctica.
Surprisingly, no evidence of high mountains, deep basins or caves has yet been found in Europe – but on very smooth surfaces, large peaks and hundreds of interconnected lines have been observed – in the Europa Jupiter elliptical orbit. Rotates, so it is sometimes too far. The gravity of this corn from Jupiter increases at the level of Europa when it is close to Jupiter and when it is far away. This changing series of gravitational pulls is called tidal flexing – perhaps tidal bending causes cracks in the surface of Europa. And the nutrients that come out of the volcano are being used by marine life – you will find examples of this kind of life in the depths of the earth’s oceans where hydrothermal vents are providing all the elements of life.
The elements that Europe needs to survive are carbon, oxygen, hydrogen, sulfur, nitrogen and phosphorus. Europa has all the things that start a simple life like water being in liquid form, the basic elements of life and the right amount of energy. These things are enough to make any simple living thing. So it is clear that if there is life in Europe, it will be mostly unicellular.
That’s all we know about Europe right now. To study this further, NASA has decided to send a mission called Europa Clipper to Europe in 2022. The spacecraft orbited Europe 45 times with its special camera and spectrometer. With its help, it will closely study the thin atmosphere of Europe. The aircraft will use water vapor passing through Europe’s South Pole to test the chemical composition of Southern Europe’s oceans to see if there are oceans. We can say that we are not alone in this universe.

ENCELDUS

In addition to Mars and Europa, there are two other places in our solar system where the chances of life are a bit higher, namely the two moons of Saturn where we can expect life, Enceladus and Titan.
Enceladus is Saturn’s sixth largest moon – about one-tenth the size of Saturn’s largest moon Titan – Enceladus’s surface is made up of fresh and clear icy water that makes it a 100% reflective body of light in our solar system. ۔ Is
The Cassini spacecraft landed on Saturn in 2001. According to Linda Spyker, a scientist with the Cassini Project, she completed 23 rounds of Enceladus and 127 Titan before successfully completing her mission in September 2017. When the first round of Enceladus was done, we found out that Enceladus is not a frozen body of ice as we thought. The temperature is higher than in other parts of it – when Cassini took a closer look at the south pole of Enceladus, he saw lion-like cracks in the lion’s body. It was hotter than parts – Cassini also detected material coming out of cracks in the South Pole – we found water vapor, salts and organic matter in the discharged material. With the help of ions and neutral spectrometers we get organic molecules up to 100 a.m.u. At present our instrument had this detection limit. “
We need to know more about Enceladus. Next time, we need to get to know Enceladus with powerful and modern tools. “
From Cassini’s plume data we find hydrogen and small nanosilica particles that form only in hot water. Hydrothermal vents are formed when seawater meets magma – hydrothermal vents have been found on land in which a unique type of ecosystem is breathing. They are used even without sunlight, so there are three life-sustaining ingredients on Enceladus, but no evidence has been found yet. It is very small and very close to Saturn so we will have to send more missions to it.

TITAN

Titan is the largest moon in Saturn and the second largest moon in our solar system. Titan is the only moon in our solar system whose atmosphere is as dense as Earth’s – scientists believe that Titan’s atmosphere is similar to that of the earliest, because Titan is geologically and chemically active.
Titan’s base is rocky, Titan’s Earth-like atmosphere is composed of 95% nitrogen, 5% methane, Cassini spacecraft and ESA’s Hagen probe

Below the surface are traces of global seawater. The planes have also detected lakes and rivers on the surface of Titan, but they are filled with liquid methane and ethane instead of water. The lake is about 1.5 million square miles wide. The lake is five times larger than Lake Superior in the United States. Islands have also been seen on this lake, but another lake has also been found in Legia Mare. Islands behave in such a way that sometimes they appear and sometimes they disappear. No one still knows what is behind them.
According to Cassini’s data, there are volcanoes on Titan, but their main feature is that they emit a cold mixture of ammonia and methane instead of lava, hence they are called ice volcanoes – of methane. Despite the effects of the green house due to the high volume, the temperature of Titan has been recorded at minus 180 degrees Celsius. Such low temperatures are not conducive to carbon-based life.
Sunlight can reduce methane in the oceans if the oceans on Titan are not muddy – computer animation has shown that the heat accumulated on Titan by the rotation of Titan and other sources is a two-way current. One is the clockwise direction in the depths of the oceans and the other is the clockwise direction at sea level. With the help of gyrus current, Titan Pay can detect oceans and heat.
At the moment we have no evidence of any kind of life on Titan, but when the sun becomes a red dwarf, the habitable zones in the solar system will change, perhaps becoming our Titan and other places.
