Discoverer: named after Edmund Halley opening date: 1758 (first predicted perihelion) Alternate designations: comet Halley (Halley), 1P Orbital characteristics: Age: 2449400.5 (17 February 1994) Aphelion: 35.32.e. Perihelion: 0.586.e. The semi-major axis: 17, 8 and.e. The eccentricity repulsed: 0, 967 Orbital period: 75, 3 and the Inclination of the orbit to the Ecliptic plane: 162, 3 degrees Last perihelion: 9 February 1986 Next perihelion: 28 July 2061 g the Period of revolution around the Solar system: from of 74.4 to 79.2 years. The average value of 76 years. Thanks to a successful “visits” in 1986 to comet Halley spacecraft “VEGA-1 and VEGA-2” (USSR) Giotto (ESA), “Suisei” and “Sakigake” (Japan) scientists got the first pictures of the core and comprehensive information:

At the science Museum in London opened a major exhibition “Cosmonauts: Birth of the space age”. It was to be the culmination of the cross year of Russia and great Britain, but now the British authorities have given guarantees for the return of Russian exhibits. Including artifacts that have never left the walls of private enterprises: the Soviet space ships, outfits, and archival documents. Tickets for the show sold out two months in advance.
This moment in London waiting for: when the world’s first woman astronaut will come to the machine in which it 52 years ago, spent almost three days, circling above the Earth.
“It’s such a faithful and reliable friend, by which without emotion could not be disregarded. And in the training center, when I meet him, every time I try to pet him and say “Hello!””, – says Valentina Tereshkova.
Spacecraft “Vostok-6” was never exported outside of Russia – like most of the exhibits of the exhibition dedicated to Soviet and Russian achievements in space exploration. A significant portion of what is now presented in the London Museum of science, and even Russia have seen a few. Continue reading
People were engaged in agriculture in the stone age, 30 – 35 thousand years ago. This is evidenced by the notches on animal bones and rocks, cave paintings. This is, perhaps, the earliest “scientific notes”, in which the authors noted the different phases of the moon and count days and nights.
Monitored by our astronomical instruments, the universe consists by weight of about 76 percent hydrogen and 23 helium. Only slightly more than one percent accounts for all other elements of the periodic table.
It is estimated that the galaxy contains more than a hundred and twenty billion stars and to represent its enormous size, we will give one comparison: if the path from the Sun to Earth light travels in 8 minutes, the diameter of the galaxy it will for a hundred thousand years.
To show the progress made over half a century in the study of the Universe, astronomer Paul Couderc came to a startling comparison. Suppose that all known astronomy to 1900 area of the Universe displayed on the plan area of one square meter. Continue reading
