NASA believes that we are now on the verge of discovering unquestionable proof that aliens are out there and they plan on delivering this proof by 2025. The space agency’s Ellen Stofan very recently stated that we should be able to find signs of alien life within a decade and then have “definitive evidence” of its existence soon after. The scientists over at NASA are confident enough to make these claims thanks to the fact that we now have the necessary means to scout our galaxy and beyond for alien life. What’s more, we also have a pretty good idea of where we should be looking for it according to Stofan.
“I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years,” Stofan said on Tuesday when she also added that “we know where to look. We know how to look. In most cases we have the technology, and we’re on a path to implementing it. And so I think we’re definitely on the road.” For those who think that Stofan’s claims might be just a bit too bold and unrealistic, rest assured that many other NASA members are on the same page as her. John Grunsfeld for example, is also of the opinion that we should be able to know within a generation if there’s life elsewhere in our Solar system and not long after that be able to effectively search for it further on planets orbiting nearby stars.
Searching for something and finding it are very different matters, but recent discoveries indicate that there are in fact plenty of other places in our galaxy that are able to sustain alien life. Better yet, some of these places are in our own back yard and include Jupiter’s moons Europa and Ganymede, and Saturn’s moon Enceladus, to name just a few examples. Despite all the evidence against intelligent alien life on Mars, there is some proof that less advanced microbial life may have lived once on the Red Planet and some of it might have survived to this day. Even if we are able to find microorganisms over there and they’re not exactly spectacular, such a discovery would certainly open up a lot of new possibilities. However, our best bet right now seems to be Europa, a moon that holds vast oceans of liquid water beneath its icy surface. As far as we can tell where there’s water there’s life, although we’ll have to wait for data from a future expedition to say for certain.
What’s even more interesting is that scientists now know that water is not as uncommon in our galaxy as it was previously believed, and neither are rocky planets like Earth for that matter. Now that we’ve identified quite a few places that could potential sustain alien life, all we need to do is go and explore them. This next logical step will require a lot of hard work given that all these places are extremely far away from our planet and our means of travelling great distances are still rather primitive. But where there’s a will there’s a way and NASA has already planned further missions to Mars (including a manned one) and an expedition to Europa, all of which will happen within the next couple of decades.
Although there’s always the unlikely possibility that an advanced alien civilization might come to visit us one day, the best course of action is surely to pour all our efforts into going out and searching for E.T. ourselves. After all, just sitting on our hands and hoping for the best hasn’t brought this far, but our indomitable will to uncover the mysteries of the universe most certainly has and it will undoubtedly also help us in finding the answer to one of our most burning questions: “are we alone in the universe?”
