Achievements in space exploration

Many thousands of years ago, looking at the night sky, a man dreamed of flying to the stars. Billions of shimmering night luminaries made him carry away the thought into the boundless distances of the Universe, awakened the imagination, forced him to think about the secrets of the universe. Centuries passed, man gained ever greater power over nature, but the dream of flying to the stars remained as unrealizable as thousands of years ago. Legends and myths of all nations are full of stories about flying to the moon, the sun and the stars. The means for such flights offered by the folk fantasy were primitive: a chariot drawn by eagles, wings attached to the hands of a person.

In the 19th century, a fantastic story appeared by the writer Jules Verne “From a cannon to the moon”. The Continue reading

Galaxies and metagalaxies

In one of his speeches, A. Einstein said (in 1929): “To be honest, we want to not only find out how it works, but also if possible to achieve the goal of a utopian and daring-looking – to understand why nature is such. “This is the Promethean element of scientific creativity.”

Galaxies have been the subject of cosmogonic research since the 1920s, when their true nature was reliably established, and it turned out that these are not nebulae, i.e. not clouds of gas and dust, which are not far from us, but huge star worlds lying from us at very great distances from us. Discoveries and research in the field of cosmology have clarified in recent decades much of what concerns the background of galaxies and stars, the physical state of discharged matter from which they formed in very distant times. The whole of modern Continue reading
