Are we close to discovering extraterrestrial life?

I saw that article when it first appeared, and I was appropriately blown away. But you have to remember that none of those amazing illustrations are photographs. The planets are much too far away for our best telescopes to see them

Do you believe in the possibility of extraterrestrial life?

Do you believe in aliens and why?I belive intelligent life exist elswere in the universe but i dont belive they are visiting the earthThere are millions of galaxies out there. with millions of solar systems each. to belive that there is no other planet among the untold billions of planets that exist that

Would extraterrestrial beings be likely to believe in capitalism?

It is possible they believe in capitalism but wouldn't see us as worth having anything to trade with.They'd still have to cope with economics, the allocation of energy, talent and resources. For example, they may have much more advanced technology but don't have unlimited resources to decide how many ships to

When will we find extraterrestrial life?

You could just as easily ask,

Would you be excited or afraid if SETI @home gets a confirmed radio signal from an alien race?

Both. I believe that in a sense, those of us who grew up in the so-called

Has SETI considered that aliens might be using the sun's gravity-well, as a wormhole generator to try to communicate with us by modulating its gravity-waves like a radio-signal?

There may well be communications modalities used by advanced extraterrestrial civilizations that we lack the ability to understand. In the past, I have joked that the aliens must be upset that we have been ignoring their blatantly obvious neutrino signals for years.I have not heard about speculation

Why is the search for extraterrestrial life is always based on water?

Any even better question is why do they always focus in on planets that are located so far distant from our own that we may never be able to interact with them even if we were able to determine that they had viable lifeforms or

What was the Wow! signal and was it really sent by aliens?

The Wow! signal was a strong narrowband radio signal detected by Jerry R. Ehman on August 15, 1977, while he was working on a SETI project at the Big Ear radio telescope of Ohio State University, then located at Ohio Wesleyan University's Perkins Observatory in

How close would aliens have to be to detect our radio signals?

Well since we have been emmiting radio signals for over a hundred years, and those signals have been traveling at the speed of light. You can then estimate somewhere within a 100 light years, but since many of those earliest signals were weak and

What other Earth species besides humans might extraterrestrial visitors initiate first contact with?

It is possible that extraterrestrial life would contact whatever life here is most similar to themselves, under the assumption that intellectual life on other planets would be like them. It is also likely that alien life from a comparable planet would look similar to the most common body type here on earth

When will we find extraterrestrial life?

I think within the next 50 years we will discover strong evidence of Extraterrestrial Life from:A) Analyzing light spectra from some Exoplanets which are not explainable by

What's the most convincing argument or evidence you've heard that extraterrestrial life existed?

I'm not sure you can claim that there is evidence that extraterrestrials exist(ed). We know about extra-solar planets and some might exist in a Goldilocks zone but the vast majority of identified extra-solar planets are hostile to the kind of life that exists on Earth.It would be more accurate to say that there

Why does the SETI program assume alien civilizations will use radio wave transmission to communicate just because mankind on Earth developed this mode?

That is an incorrect assumption as the real reason for the type of transmissions they (S.E.T.I.) are listening into are at the same frequency as Neutral Hydrogen Atoms, the most abundant thing in the Universe, in Space, as Humans know it.The Hydrogen Line:1420.40575 MHz.Info:Hydrogen line - WikipediaThe understanding is that if there are other lifeforms, hopefully

What should our telescopes look for if we are trying to find alien civilizations?

One proposed mission was to put a telescope (or telescopes) in solar orbit past the asteroid belt and look for nearby extra solar planets in the infrared light region. The premise is that planets with abundant life would be exceedingly bright at those wavelengths. I don't

Do you believe in the possibility of extraterrestrial life?

Is it possible that intelligent alien life has sent Earth a message but it just hasn't reached us yet?

Sure, very possible.As you say, a message might be somewhere in transit.Even more likely, we missed it.  Either because it came centuries ago, before we had the technology to receive it. Or they're using a technology we haven't invented yet. And most likely of

How does an astronomer face the frustration that they still find no evidence of extraterrestrial life?

I don't see how that's frustrating at all. For astronomers and astrophysicists, there are frustrations from weather, equipment problems, interesting phenomena not being visible from locations one can reach, and having enough money to do the things you want to do.Perhaps astrobiologists might find the pace of our

Does SETI actually believe they will find evidence of extraterrestrial life?

You don't do something for 50 years running and not think there's going to be a payoff at the end of it, do you?Because that's how long SETI has been at this.So, yeah - they absolutely do believe they will find what they're looking for.

As we are close to being able to build a self-replicating interstellar device, why isn't the Earth full of such devices from other civilizations?

As you said, your question is basically the Fermi paradox and there is no definitive answer.  The simplest explanation is that there are none because no one has done it yet.  One of my current thoughts on the Fermi paradox is that as technology advances it gets easier and easier to cause catastrophic

What would extraterrestrial life likely actually look like?

TL;DR: Cells, amphiphilic membranes, something similar to nucleic acids-but with a different genetic code, probably a lot of free-living unicellular life, but multi-cellular life is also likely; intelligent life is probably out there but infrequent.Let's start with the basics. There are many different definitions of

Why do people assume aliens aren't very similar to homo sapien?

Most imaginary representations of aliens are very human-like.  Those that are outside the norm, still very much resemble life on Earth. 

What is the probability of extraterrestrials intelligence travelling the Galaxy now?

Probably pretty high.The probability of there being other life in the galaxy (there are about 100 billion stars here) isn't a probability - life arises where it can, so it's almost certain that there are other lifeforms around. (The Drake equation assumed a sparsity of planets, and we now know that it's rare for

When will we engage with extraterrestrial beings?

Publicly? It would be 500 to 600 years from now. (after - the aftermath of climate change)Privately...they are...we just do not know...Thank you Harry Johnson

Do aliens exist? And why has Area 51 of Russia and the US's NASA agencies come under doubt of having their contact with aliens?

Your question is broad, but you are probably asking whether alien beings consult with NASA. First, let's be clear on one thing: despite the claims of exopoliticians, no government agency has attested to any contact with extraterrestrial beings.Now, that aside, there have been books written by

Is finding intelligent life elsewhere really likely?

We can't say yes definitely, but there is a great amount of probability that there is life elsewhere in the universe.There are at least 100 billion stars in our galaxy(Milky Way), and NASA'sKepler space observatory has found hundreds of planets just around nearby

What other Earth species besides humans might extraterrestrial visitors initiate first contact with?

Why are people only concerned about finding 'intelligent' life? Wouldn't finding ANY life be just as amazing?

It would be an equally valuable discovery in my opinion.  The chance of finding life at the same level of intelligence as us is going to be a rarity.  They'll either be eons beyond our comprehension, and perhaps, for that matter, they've been staring us right in the

What would we do if we sent humans on a two-way trip to Alpha Centauri (at close to speed of light) and to our surprise they return with some kidnapped aliens?

We would be very worried and treat the Aliens extraordinarily well , hopefully.The next big decision would be whether to and how to contact their Civilization and apologize and pray , and arrange for their return or to take them back ourselves.Not a good way to make contact.Never try to land on a Neutron Star.Never kidnap Aliens .

Is it possible that intelligent alien life has sent Earth a message but it just hasn't reached us yet?

When we make first contact with aliens, will they look like us?

According to several thousands years of data, some do and some do not.  Just look at our own specie and see the variety of configurations.  Now if we include all species of this planet the definite answer is that some do and some do not.  Even if the 'visitors' are us from the future

If an extraterrestrial life exists, would it have a consciousness?

yes why not?just imagine you are living in planet X from Galaxy Y thousands of light year from earth.then suddenly NASA equivalent (LOL) of your planet discovers X like planet (earth)and just imagine people of planet X asking questions about this :

What if there is an Earth-like planet that has a human civilization just like us, but they are not technologically advanced? Will we be able to know that life exists there?

Yes possibly, until algae and plants evolved on earth there was only a tiny amount of oxygen in the atmosphere. high levels of oxygen might indicate plant life at least.Detecting that oxygen is a whole other story and we will have to wait for new telescopes to be

When will extraterrestrial life be proven?

What you're asking for is a progress report on finding a needle in a haystack - one that's astronomically large. Moreover, just because you've searched the haystack and found nothing, doesn't mean that there was no needle to find.Sorry, but

If we send a message to aliens, how we can send them the coordinates of our solar system?

That's an interesting question and though I'm not a scientist that got me thinking. Now on earth we have a reference point for coordinates , the earth itself. Its pretty easy to locate things using the latitudes and longitudes here and if we talk about

What would be the most startling thing we could discover about extraterrestrial life?

UFOs and demon sightings... will become ‘the norm', for many people in the future.Jesus said: The reason you are talking about UFOs and demon sightings My children, is because this is what will become ‘the norm', for many people in the future. More and more people will claim

Have any governments confirmed intelligent extraterrestrial life?

No. Depending on how you define the question, there has only been one specific attempt to look for life itself (as opposed to evidence of past life) on surface of another planet, with a device sitting on that planet, and you can read about it here: Viking lander biological experiments NASA currently takes great care to avoid

Cryptography: How can the Arecebo message be deciphered? (or maximum sense be made out of it)

The "Message", if received, gives other species the knowledge that they are not alone in this universe, they might not have any clue or understanding to what this "Message" pertains but it's a conformation of life DO exist elsewhere. You think if any another kind of Alien race/species that have been

When will we find extraterrestrial life?

You could just as easily ask,

How will we most likely discover extraterrestrial life?

Great Universe, where have you people been? ET's have been on our planet for millions of years and anyone who believes in what the anthropologists are saying in mainstream anthropology concerning our evolution, is just gullible.WE HAVE DISCOVERED EXTRATERRESTRIAL LIFE, EVERYONE. IT'S BEEN SUPPRESSED BY OUR GOVERNMENT AND THE VATICAN. They don't want

Would you be excited or afraid if SETI @home gets a confirmed radio signal from an alien race?

Both. I believe that in a sense, those of us who grew up in the so-called

When and where do you think we will find extraterrestrial life?

Mars, next rover that lands, or the rover after that. We're talking either ESA's ExoMars or NASA's

Has SETI found any interesting signals?

One of the most mysterious and famous signals is the WOW! Signal.
