The mystery of the existence of extraterrestrial life is one of the most fascinating questions humanity has ever asked itself. This research, which involves the NASA and numerous scientists from all over the world, it is not just an investigation of a fantastic nature, but a real scientific mission in search of concrete evidence. Lindsay Haysastrobiologist of NASApoints out: “Are there aliens? This is a really interesting question and one that NASA has been trying to understand, explore and solve for a long time“.
Are there aliens?
When we talk about extraterrestrial life, we often focus on the most complex and fascinating life forms. However, it is important not to overlook the fundamental role of microbes. As he points out Hays,”If we look at life here on Earth, beyond the big things – the elephants, the whales, the redwoods – and focus on the little things, almost everywhere on Earth that we looked, we found microbial life“. This suggests that, although we have not yet found signs of more advanced life, we may also find microorganisms in other corners of the universe.
Conquering Mars
Mars is one of the main targets of the search for extraterrestrial life. The numerous rovers and landers sent by NASA on its surface they provided a vast amount of data and images. While we have so far found no definitive evidence of life, recent discoveries indicate that the Red Planet may have had a warmer and wetter past than initially assumed. “We have only explored a small fraction of Mars“, points out Hays,”and this is just one of the promising bodies to look for life in our solar system“.
Icy moons and exoplanets
Among the icy moons of the outer solar system, Enceladus And Europe they stand out for their potential to host life. “These moons appear to have underground oceans that may be habitable“, he claims Hays. The idea of underground oceans on other worlds opens the door to extraordinary possibilities, suggesting that life could exist in environments that look nothing like Earth.
The discovery of exoplanets has revolutionized our understanding of the universe and its potential homes. With thousands of planets orbiting other stars, the chances of finding extraterrestrial life appear to increase exponentially. “The more exoplanets we find around other stars, the more we learn about how many different environments there might be for life“, he claims Hays.
The famous quote by Carl Sagan: “The universe is a pretty big place. If it’s just us, it seems like a terrible waste of space“, seems to be fitting.
