Moon exploration

It is not surprising that the first flight of the spacecraft above Earth orbit was directed to the moon. This honor belongs to the Soviet spacecraft Luna-l, which was launched on January 2, 1958. In accordance with the flight program, after a few days it passed at a distance of 6,000 kilometers from the surface of the moon. Later that same year, in mid-September, a similar Moon series device reached the surface of the Earth’s natural satellite.
A year later, in October 1959, the Luna-3 automatic apparatus, equipped with apparatus for photographing, surveyed the far side of the Moon (about 70% of the surface) and transmitted its image to Earth. The device had an orientation system with sensors of the Sun and the Moon and jet engines running on compressed gas, Continue reading

NEUTRAL STARS

Stars whose mass is 1.5-3 times greater than that of the Sun will not be able to stop their compression at the stage of a white dwarf at the end of their lives. Powerful gravitational forces will squeeze them to such a density at which a “neutralization” of the substance takes place: the interaction of electrons with protons will lead to the fact that almost the entire mass of the star will be enclosed in neutrons. A neutron star is formed. The most massive stars can form into neutron stars after they explode like supernovae.
The concept of neutron stars is not new: the first assumption about the possibility of their existence was made by the talented astronomers Fritz Zwicky and Walter Baarde of California in 1934. (A little earlier in 1932, the possibility of the existence of neutron stars was predicted by the famous Soviet scientists L.D. Continue reading

Supernova stars

About seven thousand years ago, a star suddenly exploded in a remote corner of outer space, dropping the outer layers of matter. A relatively large and massive star suddenly ran into a serious energy problem – its physical integrity was in jeopardy. When the boundary of stability was passed, an exciting, extremely powerful one of the most catastrophic explosions in the entire Universe broke out, giving rise to a supernova.
For six thousand years, light from this star from the constellation Taurus raced through outer space and finally reached Earth. It happened in 1054. In Europe, science was then slumbering, and among the Arabs it was experiencing a period of stagnation, but in another part of the Earth, observers noticed an object glistening majestically in the sky before sunrise.
