Residents of Russia June 6 can watch the unique astronomical event — the transit of Venus across the solar disk. The next time it happens only December 11, 2117.
In the capital, everyone can see it is a rare phenomenon in the Moscow Planetarium on June 6 from 7:00 to 9:00 am Moscow time. The observations will be carried out on a 30-cm telescope, refractor Great Observatory, the ITAR-TASS news agency. In addition, the Park will be developed real sky observation sites. Here you will see this phenomenon in different telescopes optical systems with different magnification.
Planetarium professionals talk about this rare event will be introduced to the Park of the sky — Astronomical planetarium site and answer all questions. Weather permitting, it will be possible to observe this phenomenon in the rising sun and see the end. Disk of Venus can be observed along with sunspots. The observations will be carried out free of charge.
Venus begins its movement on the Sun June 6 at 02:08 Moscow time. At 5:14 The sun will rise in the capital, with Venus already on the disk, and this is one of the most exciting moments of the phenomenon. The middle passage occurs at 05:34. This is very favorable for observation, in part because of weak layers of the solar atmosphere brightness. For nearly six hours, the dark disk of Venus will move across the solar disk, and leave it at 08:57.
Observing this phenomenon in 1761, Mikhail Lomonosov discovered on Venus atmosphere. He noticed blurred edge of the solar disk at the first contact, it is called "black drop". When the black disk of Venus took part in the disk of the sun, around the edges, is still in the sky suddenly flashed a thin rim of fire. This ring is now called "phenomenon Lomonosov". It is caused by the refraction of light in the atmosphere.
Passage of Venus — is one of the rarest of predictable astronomical phenomena. It occurs when the planet is exactly between the Sun and the Earth, covering a tiny fraction of the solar disk. In this planet looks from Earth as a small black dot that moves the Sun. During the passage of Venus appears about 30 times smaller than the Sun.
Every 243 years repeated four passing, two in winter (with a difference of eight years), and then a long period of 121.5 in the year, and two more in the summer (again, eight years later.) The last passage occurred June 8, 2004.
Passage of Venus on June 6 will come from all over Russia and CIS countries. In the western half of the country's sun will rise to a planet already on the disk, so observers will be able to see only the end of this phenomenon, and it can be fully observed in the Far East and in the North, where the sun during the phenomenon does not go beyond the horizon.
