1. The search for life away from the earth
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 superclusters in this universe, clusters,
and galaxy clusters. “

2. 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.

3. 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.
1. 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 in 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

4. 1. 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

5. 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

6. 1. 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 the rocky ocean. It can be said
that rocky sea levels.

sixth closest moon to Jupiter. It is also the sixth-largest moon in
our solar system. Water is at the forefront of life-sustaining

and spread pollution — scientists say Europe may have water
derived from seawater found on Earth. Be done The surface of
Europa is the rocky ocean. It can be said that rocky sea levels.

8. When seawater is formed in the middle of seawater, chemical nutrients
are formed which are 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

9. 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.
ENCELADUS

10. 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

11. 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, and Titan’s Earth-like atmosphere is composed of
95% nitrogen, and 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 greenhouse due to the high volume, the
temperature of Titan has been recorded at minus 180 degrees Celsius.

12. 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 a 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.
