The search for extraterrestrial life has been as fiercely explored as it has been disappointing. Of course, to this point in time no planetary scientists anywhere have been able to glean actual proof of alien life anywhere in known existence. However, mathematically speaking this shouldn’t be surprising. Still, the search continues and scientists are constantly looking for new theories as to why they haven’t been found yet. It was only 70 years ago that Enrico Fermi, a Nobel Prize awarded physicist, asked the world: “Where is everybody?” He was, of course, referring to the fact that ET life had not been found. Now, Alan Stern, a planetary scientist, has chosen to offer up an explanation.
Scientists have been pouring untold amounts of money into the search for extraterrestrial life and it is one of the most important truths that these researchers could be exploring. For decades scientists and researchers have been trying to provide an answer to what we now call ‘Fermi’s Paradox’. The puzzle, which is almost certainly never going to be solved, has many different potential answers. From the thought that Earth is the only inhabited planet in the galaxy, to the concept that ET may be watching us from UFOs traveling all over the world — there are no solid answers.
Stern, who is working on the New Horizons Mission for NASA, has been active int he search for ET his entire career. Stern most recently worked with the New Horizons mission which saw NASA send a vehicle past Pluto back in 2015. Attending the American Astronomical Society’s Division for Planetary Sciences, the 49th event of such nature, Stern opened up on what he thought a possible answer to the age-old question could be.
Stern came at the concept by way of exploring the topic of what he called ‘buried oceans’. Stern pointed to the moons of Callisto and Ganymede, those orbiting Jupiter, and how they have liquid-water beneath their cold shells. Buried oceans, Stern goes on to explain, could potentially exist on a variety of different planets — including Pluto! Stern explains that these buried oceans could provide just the right environment for life to exist in all of its intelligent and complex forms. Stern goes on to explain that if these alien creatures do exist in these buried ocean environments, it is unlikely that we will ever be able to find them due to the hurdles in between their potential technology as well as ours.
