Humanity always looks at the sky and asks the same question: are we alone?
In the vastness of the Cosmos, it is difficult to believe that the Earth is the only or the first where this so abundant phenomenon, called life, occurs.
Life must have also evolved in many other corners of the Universe. Insurance. Insurance? At least, that's what logic and calculations dictate, although, for now, there is no demonstrable evidence.
But what kind of life? Like ours? How likely are we to find it? And, above all, where to look?
Through these articles we raise some of these questions and expose the answers that science gives.
Our technology explores the sky in search of some trace of life beyond Earth. At the moment, we only have silence.
