The fascination with the prospect of extraterrestrial life, be it a microbe or a UFO, has always held humans in its grip. Speculation regarding the existence of alien beings on Mars and neighboring planets has intrigued us since we first understood their uniqueness among the stars. Despite our technological power allowing us to closely examine these worlds and even observe distant planets around other stars, the ultimate question of whether we are alone in the Universe remains unanswered.
The absence of concrete evidence of life beyond Earth does not imply a lack of understanding about what could potentially exist elsewhere. As our knowledge of the cosmos expands, from the inner workings of our Solar System’s planets and moons to the vast expanse beyond, our confidence in the existence of extraterrestrial life steadily grows.
While many entertain beliefs in extraterrestrial beings, often influenced by popular culture and reports of unidentified flying objects (UFOs), scientific inquiry offers insights into the likelihood of life beyond our planet. It addresses some of the most pressing questions regarding the potential forms of extraterrestrial life that may inhabit the Universe.
So, how probable is it that there are aliens out there? Another way to think about whether aliens exist is to ask how likely it is that Earth is the only place where life has developed in the whole Universe.
Imagine there are at least 2 trillion galaxies in the Universe. Our galaxy, the Milky Way, alone has around 100 billion stars. Scientists keep discovering more and more planets orbiting these stars, suggesting that most stars probably have planets around them. Plus, as we’ve seen from exploring our own Solar System, moons can also be places where life could exist.
Where could aliens live? There might be alien life right here in our Solar System. Scientists have been exploring Mars a lot with missions from NASA and other space agencies. Mars used to be warm and wet, which means it might have had life at some point. Even though we haven’t found any signs of life yet, there could still be tiny living things there. The moons of Jupiter and Saturn also have the potential for hosting aliens because some of them have oceans of water under their icy surfaces.
Even though there’s no proof yet that aliens exist, or that they’ve ever visited us, the chances of there being life beyond Earth are so high that we absolutely have to keep looking.
Every time we send a mission to explore a new world, every time a space telescope gazes at a distant star system, and every time a radio telescope listens for signals from another civilization, we humans are gaining more knowledge about the Universe we live in. Through this exploration, we also learn more about ourselves and where we fit into the grand scheme of things. And even if we never discover other life forms beyond our planet, it’s reassuring to know that in the vastness of space, we’re most likely not alone.
