Fomalhaut b, the planet that was seen in visible light

Fomalhaut is a very young star, and there are massive clouds of dust and ice around it. Hubble discovered the formation, what looks like an exoplanet orbiting it, but then something happened. Fomalhaut b vanished, but then it was found again, and the thing is that this exoplanet is first, what was seen in the visible light. The straight observation of that planet was made by Hubble space telescope. 

The thing is Fomalhaut b is a zombie planet, what temperature is too high for lifeforms. And the Fomalhaut is a too young star for complicated lifeforms. But the finding of that planet was one of the most interesting parts of history. The age of Fomalhaut is about 100-300 million years, and that gives us the possibility to observe young and forming solar systems, and the possibility that somewhere in distance is the star, what is similar to Fomlahaut, but older. And maybe there is the living exoplanet. The problem is that Fomalhaut is the spectral type A star, which makes it like Sirius. There are also two other stars in that system Fomalhaut B (TW Piscis Austrini), what is K4 star, and Fomalhaut C. (Capital letters are for stars, small letters are for planets). 

At this point, we must remember that we are thinking that G-type stars are the best and suitable place for lifeforms, which are like us. So in this way, we believe that intelligent lifeform is a copy of us. And the blue stars would live too short time for creating intelligent life. But search never ends.

The short period of life could be quite common in the universe

Maybe there were primitive eucaryotic lifeforms on many other planets before they froze to the cold and dead worlds. In theory, those lifeforms could be used volcanic temperature until the nucleus of the planet was frozen. When the rocky planet is forming it is the giant magma ball, but when the temperature is decreasing, there could be a short period, when that planet is a suitable place for the primitive lifeforms. 

But that period could last less than two million years. So could there form primitive lifeforms? That is an interesting question. 

Short-living stars might be a more suitable place for forming the primitive lifeforms than colder and smaller stars. But those lifeforms would ever turn intelligent because the star is so short living. And at this moment we must realize that there could be also a short period of lifeforms on other planets in our solar system. Maybe even Pluto had the primitive proto- or procaryotic cells, which got their energy from the volcanic temperature before the planet was frozen. 

Here I think that Pluto is like other planets, and it has the past as the lava ball, like every other planet. And maybe there was a short period primitive lifeforms, what was similar, that was found near black smokers. But the planet was frozen, and life was gone. At this point, we must realize, that there is a possibility that the planets have changed their positions and trajectories in the solar system. Because the impacts with giant asteroids were common in the chaotic past of our solar system.

There is a possibility that there are active lifeforms under the ice of Europa-moon of Jupiter.  There is no evidence about that kind of life, but there is a possibility that there is some kind of bacteria under the ice core of Europa or Enceladus moon of Saturn. 

Possibility to find the fossils of procaryotic organisms from other planets is an interesting and exciting vision. And there is a small possibility that deep underground of the planet Mars is found the genomes of those bacteria, what might live on that planet may be less than a couple of million years. That time would be very short, and maybe those primitive bacteria that might be similar to our cyanobacteria were the top and the most advanced organisms on that planet. 

The geological catastrophes of the planet Mars were rougher than on Earth, and when it lost it's lithosphere all evidence of the complicated lifeforms of Mars disappeared. Mars might have free water on its surface short time before the core of the planet froze to that temperature, which is extremely low. 

And planet Mars like every other planet was not frozen in seconds. That means that there was the ice core was growing and the ice age was covered the entire planet. Then the ultraviolet radiation broke the water molecules and weak gravity couldn't keep the oxygen in the atmosphere, and the UV radiation sterilized the ground.
