The existence of life in space


With the advancement of science and information technology, there is no end to the curiosity of scientists about the existence of life in space and space.


Scientists are hopeful that life could be found on different planets or satellites.

The existence of life on Mars


According to Professor Grady, life can be found on Mars. However, it is very unlikely that any life of very advanced intelligence can be found there. According to Grady, if any life can be found on Mars, it will be very small. Almost like bacteria.


Around 180, the astronomer William Herschel gave a theory about the size of the creatures on Mars. According to him, the creatures on Mars will be taller than humans.

He observed the size and seasons of Mars with a more powerful telescope than Galileo's time.


As Mars is smaller in size than Earth, so its gravitational force is less than that of Earth. Therefore, it will be possible for the living beings there to be taller.


The existence of life in Jupiter's satellite Europe

Scientist Monica Grady commented that she was almost certain that Jupiter's moon existed in Europe, but that it was more likely to be an alien that could not speak or move.

Professor Monica Grady thinks that life could exist under the ice of Europe. The Europa satellite is 15 miles full of ice.


The existence of life on Saturn's satellite Enceladus

The Enceladus satellite is covered in ice. Below is a liquid sea.

It is thought that the lower part of the ice cover is liquid because there must be some kind of heat source.


Our earth has a kind of heat dissipation crack or pore at the bottom of the ocean. As a result there is a kind of reaction that helps to prepare food for aquatic animals.

Scientists speculate that Europa or Enceladus may have had a similar process on the moon or some other ice-covered satellite.


However, according to Professor Grady, "the distance from Earth to other planets is so great that it is never certain whether we will ever succeed in finding life on those planets."


He added: "Unfortunately, none of the signals that have been found in space so far are sufficiently acceptable or genuine.


The way scientists look for the existence of life in space


Astronomers estimate that there may be as many as 40 billion planets in the Milky Way galaxy.


Scientists have identified about four thousand planets outside the solar system. These are called exoplanets.

Colorless and odorless methane gas is emitted from the bodies of all the animals in the world. Methane gas is emitted from the bodies of all people starting from termites. But methane gas is also emitted from volcanoes

Scientists consider the "exoplanets" to be the ideal place for life to exist outside of Earth, because of their environment. They are not too far from their own constellations, not too close.


Therefore, most scientists believe that these exoplanets are more likely to have a source of life.


So they think that more research should be done on exoplanets to find the existence of life in space i.e. aliens.
