<p>Alien hunting is a hopeful activity and one reason behind our space programs that the public generally supports. Looking for other life is a strong incentive to be venturing out into space, despite having found none so far. A top British space scientist,<strong> Professor Monica Grady,</strong> gave all cosmic explorers a big dose of such hope in a recent speech. She is certain there’s some form of life on Jupiter’s moon, <strong>Europa</strong>.</p><p>This life would not look human, but more like an “octopus,” and is likely residing in the cold waters under the moon’s sheets of ice. </p><p>Grady, a Professor of Planetary and Space Science and Chancellor at Liverpool Hope University, thinks there’s a great likelihood of undiscovered life somewhere in our galaxy.</p><p>She also supposes that the deeper caves and cavernous spaces of Mars could be harboring some subterranean creatures, likely bacteria, there to escape the solar radiation. They could be getting water from the ice buried deep down. </p><p style=”margin-left: 20px;”>”When it comes to the prospects of life beyond Earth, it’s <strong>almost a racing certainty </strong>that there’s life beneath the ice on Europa,” <a href=”https://phys.org/news/2020-02-certainty-life-europa-mars-uk.html” target=”_blank”>she said</a> in a February address.</p>

<p><span style=”background-color: initial;”>She thinks these life forms on Europa, </span><span style=”background-color: initial;”>390 million miles from Earth, could be higher in sophistication than the Martian bacteria, possibly having “the intelligence of an octopus.”</span><br></p><p>Where would the creatures live on this moon of Jupiter? Somewhere below the very thick layer of ice, which goes 15 miles deep in some places. It’s possible there is liquid water beneath all that ice, keeping whatever lives inside protected against radiation and the impact of asteroids and similar smashing bodies.</p><p><span></span><span style=”background-color: initial;”>The likelihood of life on Europa is bolstered by </span><span style=”background-color: initial;”>the possible <a href=”https://ui.adsabs.harvard.edu/abs/2011AGUFM.P23D1743G/abstract” target=”_blank”>hydrothermal vents</a> on its ocean floor. Such vents are cradles of life on Earth.</span></p><p>Grady thinks that our solar system doesn’t have to be particularly special and that statistically speaking, as we explore other stars and galaxies, we should be able to find conditions for life. “I think it’s highly likely there will be life elsewhere—and I think it’s highly likely they’ll be made of the same elements,” <a href=”https://phys.org/news/2020-02-certainty-life-europa-mars-uk.html” target=”_blank”>stated</a> the professor.</p>

<p>Grady did not want to guess whether we would contact extraterrestrials any time soon, citing the fact that distances between us and likely aliens might be gigantic. </p><p>On the other hand, she added, if you look at a grain of sand, you “can see that most of it is made up of silicates, but it’s also got little patches of carbon in it—and that carbon is extra-terrestrial, because it also contains nitrogen and hydrogen, which is not a terrestrial signature.”</p><p>This tiny sample, says Grady, shows it was hit by meteorites, asteroids, and interstellar dust, pointing out “It’s giving us an idea of how complex the record of extra-terrestrial material really is.”</p>

<p>As for Europa, it has certainly figured in conversations about alien life previously. As <a href=”https://europa.nasa.gov/mission/why-europa/” target=”_blank”>NASA explains</a>, scientists call Europa an “ocean world” due to decades of observations that predict an ocean under its sheets of ice. </p><p><span style=”background-color: initial;”>In 2019, water vapor was confirmed there by NASA for the first time. While it might just have the right conditions for life, </span><span style=”background-color: initial;”>does this moon have little octopus E.T.s swimming about? Future studies will tell. </span></p>
