Do Aliens Exist?

You mean there are only eight planets in our solar system. The Milky Way is the name of our galaxy.

 

There are some Scientists that are suggesting that life can exist in a planet's moon, such as on one of Jupiter's moons, Europa to be exact:

http://en.wikipedia.org/wiki/Europa_%28moon%29

Also, there was a feature article or documentary (if it could be called as such) on National Geographic on a "possible" extra-terrestrial life sustaining planet scenario which is on a moon instead of a planet which was named "The Blue Moon".

Crap! The video is no longer available on Youtube

Another "would be" scenario in that documentary was a world that has it's axis synchronized with the planet's rotation so as one side perpetually faces it's sun & half eternally in darkness. That segment was called "Aurelia", if I got the spelling correctly.

 

It was already said, but I'll repeat it just for you. A moon is not a planet, that's why it's called a moon.

wait... wut? There's no evidence of alien life, but there's evidence of alien life on Mars, yet there's no evidence of alien life. My mind is well and truly fucked.

 

Lol, ok, sorry about my confusing post.
There was a meteorite from Mars, found in Antarctica, which shows what could be (notice the bold) fossils of ancient bacteria.
As of yet, it has not been proven to be bacteria, but there is a big possibility that it is.
So yeah, there still is no concrete evidence for alien lifeforms.

Yes they exist. We see an alien every time we look in a mirror.

 

Wrong.
I can't see my own reflection in the mirror because i am a vampire.
So there.

 

Just a question, wouldn't a moon be considered as a satellite, since it orbits around some form of object capable of density. Because as we all know that if any material that has volume and mass there is bound to be clutters of debris attracted to it.

I heard that Mars sometimes has polar regions within its atmospheres that sometimes get frozen. This is so close to sustaining life. It's just that most of the planet is barren and too distant from the Sun. All of the planets would need something similar to Earth's design in order to have an abundance of life. Natural ingredients are the basis forms of life.

 

Yes.
And it is thought that Mars used to resemble Earth a lot more in the distant past.
It probably was able to sustain life (it still probably can, as you said yourself, just not like it used to), and there is the possibility that it did (see fossiled bacteria in previous posts).

Every planet can sustain life ;D Just that the type of life found is unknown ;D

 

Hmmm, maybe not every single planet.
But yeah, there is the possibility that carbon life is not the only type of life in existence.
Far-fetched, IMO, but the possibility is there.

 

wait for it....

Yupe it was bumped out because the astronomers thought it lagged elliptical orbit and thus stayed in place for a very long time. The planet seems to be debated about whether it should become a hunk of solid ice or lifeless moon. I was taught that the darn thing was part of the galaxy until three years ago...

I have inclinations that it should be considered a planet because it does have a way of going about the Sun. I see that pluto has no other means of having life, but it is still there within the galaxy's boundaries.

I have been looking into the theories of TERRAFORMING. And this stuff is quite intriguing.

 

when we terraform a planet then life develop there re they still considered aliens?

 

Yes, they would be because they exist on another planet comprized of different matter.
Bacteria once was the only living source of life on Earth, so if the same were true for other planets then it is possible, no doubt.

 

Hey guys, according to what I have researched. There seems to be a four dimensional gateway in Earth that actually links you to the alien world. However, all living and non-living objects are three dimensional, so any chances of us getting into their world is like kind of low. Shadows are two dimensional ;D Google "possible Four dimensional gateway" ;D

 

It's orbit was not the main reason as to why it lost it's planet status.
It was because Pluto is just one of many similar dwarf planets that form the Kuiper belt.

If the life really is developed there, and not transported there, then yes.
Even if life was transported there, and evolved into something different, i would say it would gain "alien status".
EDIT:
This might be a little confusing, so let me try to simplify my opinion:
If all that happens is that the life we brought there survives and multiplies, then no.
If on the other hand, it's evolution changes some aspects of it, which make it even slightly different from the mother, earthen, species, then i think it should be considered alien.
If it evolves into diferent species, then no doubt, those species would be alien.
Considering the way evolution works, it is almost guaranteed that we would end up with alien life forms.If whatever life we brought to said planet was able to survive on it for an extended period of time.
