The universe is an amazing place with endless spaces, millions of different objects and mysterious formations, the true structure of which still remains a mystery. In the heap of everyday worries, we forget how unique creatures we are. Most often, our life is focused on a particular city in which we were born or work. Periodically, these scales increase to the borders of the native country. Some manage to visit several countries. But even the happiest people are not able to visit every corner of the Earth and get acquainted with the diversity of cultures, terrain, nature and other attractions. And yet travelers are incredibly developed, as they learn to see a complete picture of the world and to realize the value of life.
But this is only the Earth. And now let's increase the parameters and choose a landmark in the form of a kind of polar star http://cosmosplanet.ru/zvyozdy/najti-polyarnuyu-zvezdu.html, which for millennia served as a faithful guide for the researchers who had gone astray. Even the ancient Greeks came to the understanding that the world can not be limited to just one planet. There were thoughts about the existence of other objects that revolve around us. The shift came with the Copernican system, who declared that we live in the solar system, where everything revolves around a single star. For many, it was really a huge shock, because man was now perceived only as a minor detail in a giant picture of the system. Space can be shocking. Many scientists studying planets, stars, galaxies and distant quasars sincerely adore their profession. After all, they got the opportunity to go beyond the borders of their native Earth and to visit at a distance of millions and even billions of light years when the Universe was just beginning to develop. Interest and curiosity pushed humankind to create the first satellite, launch a rocket and a man into orbit, create a space station, visit the moon, send probes to asteroids and other planets, as well as exit of one of the vehicles (Voyager) to the interstellar medium.
Previously, stars were perceived with a divine context. Then they became landmarks for sailors, like the famous North Star, which is part of the Little Bear. Now they are studied with interest by researchers, understanding the composition, brightness level, impact on the life of planets located nearby, as well as the processes of their formation, evolution, death and subsequent transformation. But this is not the limits of our capabilities. Modern devices and telescopes are so powerful that they can unwind time back and go at times when the space was still young. Scientists do not stop and future technologies will try to discern the moment of the Big Bang, that is, the point from which the history of our Universe began more than 13.8 billion years ago.
Why does space exploration become a priority? First of all, it is a scientific interest, namely the desire to understand the structure of the world in which we exist, its laws and rules. We have already learned a lot, but there are still more mysteries. For example, many have heard of black holes and blazars, but there are also white holes, as well as various theories about the multiverse and parallel universes. It is also interesting to learn not only how it all began, but also to which of the proposed finals we will come. The second reason is more prosaic and lies in the security of humanity as a species. Our planet in the past many times experienced catastrophic collisions, one of which destroyed the dinosaurs. There is no guarantee that this will not happen again, so astronomers keep an eye on astroids and invent various ways to save the planet. Do not forget about colonization. After about 5 billion years the Sun will grow in size, approaching the point of its death, and the Earth will become unsuitable for life. By that time, it is important to master at least Mars in order to stay alive. Of course, this is a huge period of time and there is nothing to be afraid of in our era, but it is worth thinking about future generations and the survival of Earth species.
You could already be convinced that the Universe is a mysterious and amazing place worthy of your attention. On the site you can get acquainted not only with the planets of the Solar system, but also explore other stars, galaxies, constellations and other objects. The most curious researchers open headings with interesting facts.
