Are We Alone?
Questioning whether Alien life exists or not is something that people have done for decades.
In 1899, Nicola Tesla claimed he had tuned in radio broadcasts from Mars, history’s first reported extraterrestrial signal.
Whether what he claimed is true or not its hard to imagine that among the Trillions of planets, Earth is the only planet with life.

As technology progressed we humans have ventured far from our home planet, in the hope of finding living organisms, proof that we’re not alone. We, of course, haven’t found any yet. But a growing amount of data has given us a better sense of where in the solar system we should look.
Although we probably won’t find Thanos with his infinity gauntlet, that doesn’t make the prospect any less exciting. Here are our 5 best chances at finding life in the universe.
5)Titan

Titan the largest moon of Saturn and the only known moon to have a dense atmosphere, it is also the only object in space other than Earth where clear evidence of stable bodies of surface liquid has been found.
Titan could potentially harbor life but not possibly in the sense that we think.
It has water, and it has liquid. It just doesn’t have liquid water.The water on this moon is completely solid because of the extremely cold temperature. On the surface there are lakes and streams of liquid but the liquid that fills the lakes and streams is not water but rather hydrocarbons mainly methane and ethane; and some scientists speculate that these liquids might take the place of water in living cells different from those on Earth.
4)Europa

One of Jupiter’s moons here Europa is another candidate due to its potential to hold liquid water. Europa is thought to have all the necessities for life including water, energy sources, and the right chemical buildup. The water is thought to be stored in oceans underneath Europa’s surface.
According to scientists,Beneath its outer shell of ice, estimated to be 10 to 15 Kilometers thick, there is a vast global ocean three times the volume of all the oceans on Earth. Intense tides caused by Europa’s interaction with Jupiter and its other moons creates friction that generates heat, keeping the ocean warm.
In early 2017 a mission called Europa Clipper is launched and it would take place over the next several years. Its main mission is to analyze the moon and search for life.
3)Enceladus

The sixth-largest moon of Saturn. It is about 500 kilometers (310 mi) in diameter,and a tenth,Titan in size.
Enceladus has the astronomy world abuzz with its potential to hold water, unlike its hydrocarbon-rich sister. The water is supposedly underneath the crust of the moon, similar to Europa.
Once again, this would mean that microbes of some kind live there. At first, the presence of water was simply a hypothesis after some evidence found in 2015 gave scientists hope.
In early 2017, a mission involving the Cassini spacecraft detected hydrogen molecules that point to a chemical reaction under the surface. This reaction, in which the ocean water reacts with surrounding rock to produce energy, could be useful to life-forms because an energy source is crucial to life as we know it.
2)Ganymede

The largest moon of jupiter and ninth largest object in the Solar System,made famous by the tv show and book series the expanse Ganymede is thought to have an ocean beneath its crust. Surprisingly, this ocean could contain more water than Earth itself. In fact, investigation into Ganymede’s surface shows that there may have been a flood once when liquid water escaped from beneath the surface through cracks or other openings.
1)Tabby’s Star (KIC 8462852)

Situated about 1,300 light-years from Earth its a flickering star, first described by Louisiana State University astronomer Tabetha Boyajian (aka Tabby),This star has received a lot of buzz for supposedly being the host of an “alien megastructure.”Nothing about this star makes sense. It gets dimmer and brighter at seemingly random intervals. It also seems to be slowly but steadily becoming fainter — and yet there’s nothing about the star or any kind of surrounding material that would explain this behavior,According to the scientists if an advanced civilization built vast, irregular structures in orbit around their star, that could explain both the flickering and the gradual dimming.
So what do you think about life on other planets, Do u believe in it,tell me in the comments
