LIFE BEYOND EARTH:

Hi there I’m ‘Karthik Dadi this is my article about the extraterrestial life.

Is earth the only planet with life??

May be “No” or “yes”? This will be the answer of the person whom you ask. Even the scientists had the same doubt  whether life beyond earth is there or not.

The search for aliens is the man’s one of the greatest challenge ever. Even our scientists and astrophysicists are trying in different ways to find the truth behind this. The main aim is to find are we alone? if no, are they some species living?, if yes how will they look. Not only these, there are many doubts about the life, universe, galaxies. Etc.

 After a seven years journey “Cassini Huygens Probe Mission”. Actually this is travel to Saturn’s moon titan. The surface of titan is covered by thick orange layer which covers the whole moon. Actually its size is bigger than the planet mercury. The probe entered the layers and saw mountain like structures which same looks like that of earth. And the probe landed on surface and the surface looks like dessert and having smooth rocks (better to call pebbles which we can find near river beds) and the main thing that probe noted is that at some places the surface is wet. Then the Cassini’s radar sweeps the surface it found the there are hundreds of lakes. But the temperature in titan is -290F. So the water should get freeze and all the lakes should be frozen and should look like Antarctica. Then what is this liquid??

Cassini’s radar took the readings of the liquid are not consistent with water. The liquid is liquid methane and ethane which are volatile and flammable gases on earth. The mountains are of frozen ice. Probe details about the thundering and raining. Actually the thunders are same like as on earth the rain is actually of methane and ethane and the drops falls slowly due less gravity and the size of drops is much bigger than water droplets we see when it rains. According to scientists Chris McKay there may be some micro organisms which live in those lakes of methane and ethane. But there is no evidence that any micro organisms live in those lakes.

If life could have evolved on world as drastically different as earth and titan  then perhaps life could evolve in many other ways on many different world after all we are just a some species living on planet

The three components needed for the life are found on earth they are

i) Carbon dioxide and others like nitrogen and oxygen

ii) Water

iii) And the last thing is sun

These three are important for the existence of life. Now the doubt is that Is earth the only planet with all these three components available?

Stay tuned i'll write the next part soon!!
