About Search 4 Xtraterrestrial Life

In this blog, I talk about how aliens might live, how their bodies might function, what types of aliens there might be, and the possible structures in an alien society. I bring you up-to-date news about anything in space involving the possibilities of life. Also, I talk about the histories of our own species, and their endeavors into space. Please subscribe to my blog, and enjoy reading it!

Alien Languages and Speech

Last night I watched Star Trek, in an episode where the aliens spoke English, except they spoke in metaphors. In reality, aliens would not speak English. In fact, they might not even have earth-like vocal cords. Aliens might have liquid in their bodies which emanates noise outwards. They might communicate in ultra-high or ultra-low frequencies, or use telepathy. Aliens could use sign languages or movements to say things. If humans find alien life, we might not be able to ever understand them. We may find out how these aliens communicate, but we might not understand them.

What Might Affect Alien Life?

Location, Location, Location. It might not matter on how far from a star the planet/moon is, but on how geologically active it is. Triton, a moon orbiting around Neptune over 2 billion miles away from the sun, may support bacterial life forms. Triton is home to a deep system of hydrothermal vents, with ammonia ice slush on the surface and warmer, possibly liquid soup in its interior. Io is the most volcanically active body in our solar system, with its molten surface always changing due to the intense gravitational pull of Jupiter. Europa may have a vast ocean under its surface, though we do not know how earth-like life may breathe here. Mars, a likely candidate, was likely to have had previous life; any present life is deep under the surface. Venus may host many species of extremophiles living off of its carbon atmosphere. Triton has many methane lakes larger than Lake Michigan, and "snow" that creates dunes over 7 x the size of those on Earth. These diverse enviornments may harbor life very different from our own.

Extremophiles - Food for thought

We have found many diverse life forms on our planet. The hardiest of all life forms on Earth are a group of bacteria called extremophiles. Last year scientists thawed out bacteria over 50 thousand years old; the bacteria, after unfrozen, was alive! This shows that life, even on Earth, are prepared for harsh conditions. There are many variants of bacteria that live near melting lava, grow in 7,000 degree F, and underground under enough pressure to crush a human being. One bacteria, found over two miles underground, is able to withstand over 1,500 X the radiation of a nuclear bomb. Another is able to breathe not oxygen, but carbon dioxide. Our life forms here on Earth are diverse; how complex might other life forms be?
