More about theoretical extraterrestrial lifeforms
We must confess one thing, and that is we cannot know, what would some extraterrestrial lifeform look like. Because we don't have straight prove about the existence of that kind of lifeform. And if we are thinking about the fossils of planet Mars, we have not thought that they might become from Earth.
When the giant meteorite hit Earth, that could throw water and other kinds of things even to space, and those ice bites can drop to Mars. But as you see this is one of many theories about this kind of thing. The life in the universe might be very common, but intelligent lifeforms might be a very extraordinary thing.
And the thing is that culture and technology are a little bit different thing than some kind of intelligence. This makes things like SETI-program so fascinating but in the same way so difficult. We don't know, what kind of things those organisms do, or what they are looking like, but as you see, we must say something.
Those hypothetical organisms might live in different kind of conditions, and thing what is poisonous for us might be important to those aliens. If the conditions of the hypothetical planets would be similar to Earth, but there would be the giant landmass, there might live lifeforms, which cannot ever drink water.
For those creatures, water can be poison, because it breaks the cells, and they can get all water from the food. In some other scenarios, aliens would live in the conditions, what is full of acid. In that case, those aliens might have slime cover, which isolates the body from the acid, or their skin would renew very fast because acid would remove cells away from the skin of those creatures.
And for those organisms the conditions, where is no acid can be deadly, because the slime would sink that organism, or their skin would become too thick, what might cause death. Same way if the aliens would live in carbon dioxide, that means that pure oxygen would burn the mitochondria of those creatures. But those aliens are only hypotheses.
Van Maanen's star and Epsilon Eridiani's connection with SETI-program.
Van Maanen's star (Van Maanen 2) (1) is a white dwarf and one of the nearest stars of our solar system. The distance to that white dwarf is 13,9 light-years from us. The thing that the Sun would transform into a white dwarf at the end of its life has caused an idea that or theory, that this star might have civilization, what has moved to another solar system There is no proof about the civilization but the thing is that Van Maanen's star has once been giving fascinating ideas in the mind of SciFi writers and theorists, who have got idea, that this hypothetical civilization would move to Epsilon Eridani, before the Van Maanen's star has erupted as nova. But there is no proof about that.
Epsilon Eridani is one of the stars, where is looked at the intelligent lifeforms. The star is very well-known because the OZMA-message (3) would send it to that star. This star is too young that scientists say that they could find intelligent lifeforms or civilization around it.
And that star is only 0,7 mass of the mass of Sun. The thing is that Epsilon Eridani is cooler than our sun, and if there could be the aliens, they would not feel comfortable on Earth, because the sun is so bright, that the skin of aliens would burn. But there is one remarkable thing in that star and the solar wind of Epsilon Eridani is very strong, 30 times more powerful than the sun (4). That tells a very strong magnetic activity. Maybe it is caused that the star is very young, but there is another explanation for that.
And that means that there have been happening something, what causes that effect. So is that star faced the GRB (Gamma Ray Burst), which means that it would get extra energy dose. That thing can cause that magnetic field would get stronger. But the energy for that thing might be caused by some other reasons and is it possible that the overactivity of Epsilon Eridani causes that the star has impacted with some red dwarf.
