Astronomer Fyodor Bredikhin

Astronomer Fyodor Bredikhin was born in 1831 in the city of Nikolaev in the ancient noble family.

To 14 years Bredikhin was home-schooled – in the estate of her father Colonie near Kherson. Then was sent to boarding school at Richelieu Lyceum in Odessa, and four years later transferred to the Lyceum. However, studying in the lycée he did not like, and in 1851 he transferred to Moscow University physico-mathematical faculty.

Bredikhina was interested in physics, but, obeying the fashion of those years, he intended to follow in the footsteps of his father and uncle, that is certainly to enroll in the naval service or in the artillery. Only in the last year after practical work in the Observatory Bredikhin became interested in astronomy.

In 1862 he defended his master’s thesis “On the tails of comets”. This study as would be anticipated the main direction of its future work in astronomy.

In 1867 Professor Bredikhina was granted planning a business trip. Good knowledge of the language enabled him, while in Italy, to be familiar with the works of the Society of spectroscopy. Many Italian researchers have become his friends, including the famous discoverer of the “canals” of Mars the astronomer Schiaparelli. Continue reading

The discoverer of the ninth planet

DWARF PLANET

They dived to the bottom of hell, under the thick neon-methane atmosphere of Pluto. Flew in the snow storms of ammonia, every second fearing a break in the dark about huge needles durable as steel, water ice. They managed to find an area where there are mountains. The mystery of Pluto has been solved at last — this planet belongs to our Solar system. She captured her during the journey of the Sun through the Galaxy.

SEARCH OF THE WANDERERS

Amateur astronomer William Herschel, discoverer of Uranus

The discovery of Pluto, which for a long time officially considered the ninth planet of the Solar system, has its own history. Before the advent of telescopes humanity were well known five celestial bodies called planets (from the Greek for “Wanderers”, “wandering”): mercury, Venus, Mars, Jupiter, Saturn. During the four following centuries managed to open two more major planets, Uranus and Neptune. Continue reading

Solar system

It would seem that in the Universe can be arranged easier and more reliable than our Solar system . A crucial role is played by force of gravity; the motion of each planet around the Sun is subject to clear and unambiguous laws – the laws of Kepler; this movement is almost the same, common to all planets, except Pluto’s, the plane.

In reality things are not so simple. The fact is that on each of the planets of the Solar system is not only the power of solar gravity, but the force of attraction of the other planets. This pull causes disturbances in the movement of each of the planets of the Solar system. Several planet deviates from its normal path prescribed by the laws of Kepler, however, every time returning to it. When you consider that the mutual position of the planets of the Solar system changes all the time, it becomes obvious that the overall picture of their movement very difficult.

And so the question arises. If the perturbations of the planetary movements of the Solar system lead to irreparable disaster? Where is the guarantee that whenever getting off the rails invisible space, the planet will return to a “native” orbit? But if the deviation is too large? And if all this “inside buildup”, a kind of vibration, to cause Ravalomanana system? Continue reading
