5 things you need to know about aliens

The 'Goldilocks' idea is actually misleading in my opinion. Might be applicable if you want to define life as something like us, but life will find a way to exist mostly independent of the environment.

Even on earth we've found life where it was thought impossible to exist due to high temperatures or pressures.

Came here to say the exact same thing.

If bacteria can grow and thrive in boiling hot geysers like in Yellowstone National Park, then life could easily exist elsewhere outside the "Goldilocks" region as well.

^^ #1 no longer valid, extremophiles can survive pretty much any conditions

What scares me, is the fact that these aliens might be very dangerous, and we just sent them a gift card saying come to earth and destroy us....

I hope you being extra sarcastic?

This planet is 1400 light years away - one light year is around 10 trillion kilometers. No message from earth is getting there soon. By the time it does we would either be so advanced you wouldn't recognize our species and we would be the threat, or we would have destroyed ourselves.

The concept has been challenged since water was discovered outside the zone on liquid carrying bodies and on 'candidate' planets positioned outside their respective habitable zones. The Goldilocks concept is now probably 50+ years old, however when searching it would be more likely to discover alien organisms within habitual zones, or as per the later galactic habitable zone (GHZ) concept. To note, Goldilocks are the circumstellar habitable zone (CHZ) concept. I am also in the opinion that the entire galaxy may be habitable in one way or the other, our knowledge on biology is limited to Earth, to what was carried to Earth, and to what we already gathered by visiting space, Luna and Mars.
 
Article skips the most important thing anyone should know about aliens(the aliens form another planet variety) : We haven't actually found any.

was going to post the exact same thing.

We looking at "aliens" as being similar in composition to our own make up and functions. you get hypoxic, anaerobic, thermophilic, halophilic and other bacteria's that grow in conditions not conducive to what we see as "normal" growing conditions. It just means that they can thrive in harsher conditions and may evolve into other types of living creatures.

And? That doesn't disprove their existence
Absence of evidence is not evidence of absence

If this guy is correct, then it is very likely there are other forms of life in the universe.

Interesting story, and interesting comment under the story:

The theory for the origin and evolution of life as presented above and accredited to Jeremy England is not new. It was published by myself in 2009, K. Michaelian, arXiv:0907.0042 [physics.gen-ph]
http://arxiv.org/abs/0907.0042
and again in 2011, K. Michaelian Earth Syst. Dynam., 2, 37-51, 2011
www.earth-syst-dynam.net/2/37/2011/doi:10.5194/esd-2-37-2011
The observation that under a generalized chemical potential material self-organizes into systems which augment the dissipation of that potential should be accredited to Ilya Prigogine, “Introduction to Thermodynamics of Irreversible Processes”, John Wiley Sons Inc., 1968. I have written a number of other papers on the thermodynamic dissipation theory for the origin of life, including an explanation of homochirality. These papers are freely available by searching for my name “Karo Michaelian” on ResearchGate. I welcome Jeremy’s contribution to the effort to understand life from a thermodynamic perspective.

Regardless, considering the staggering number of stars in the universe and the number of planets in the Goldilocks zone that must orbit them, I find it impossible to humour the idea that we're alone in the universe, or even the only intelligent lifeform in the universe.
 
Mmhe! Mmhe! Aliens this aliens that for how long? Man these guys are good at hidding, people are going nuts trying find these guys. Wow! Aliens help me hide from my boss & GF please guys.
 
Shut up about the bacteria...who wants to travel light years to find amoeba? It's pretty obvious aliens means some lifeform capable of understanding gravity i.e. why the moon \ earth is not flat...
