\"On<\/a>

On the threshold of creation<\/p><\/div>In the beginning, there was nothing but dust<\/a> and gas of light elements<\/a> concentrated in smaller and smaller piece of one arm of our Galaxy. But then it started: In some part of that nebula<\/a> the temperature with pressure and density indefinitely rose up until a critical point was achieved and new star has born<\/a> in that place. Rest of the material was used for building of bodies of the Solar System<\/a>, such as planets, asteroids, comet nuclei and … life<\/a>, eventually. What we know, that happened only on one planet, called Earth. It started over 3 billion years ago with simpliest forms of organisms, but the evolution<\/a> continued successfully, despite some catastrophical event in Earth history, to its current peak: the human beings<\/a>. The (probably) first inhabitant of this planet to be able to realize their existence in the Universe. And also the possibility of birth of life in any other place in our cosmic neighborhood. This is exactly what I felt on 15 January 2019, while sitting on almost untouched dune of Viana Desert (Boa Vista Island, Cape Verde) and watching the rising Carina nebula<\/a> over the horizon. Namely that nebula is one of the largest stellar nursery in the sky, most likely a place of habitable planets as well.
