How To Decorate A Dvd Cover







With the nose up


Tuesday, August 10th will be the Night of Saint Lorenzo, or the Night of shooting stars during which (according exactly to the nose and up) you can enjoy a double-show heaven.
The light rain of meteors - which this year promises to be extraordinary for its dense and visibility - will be preceded by an unusual phenomenon at sunset: three planets next to each other, apparently very close, forming a small triangle horizon.

The swarm of meteors - also called Tears of St. Lawrence because it breaks the atmosphere of the Earth to coincide with the anniversary the death of the saint - in fact it will be visible from this evening and for the next 6-7 days but the peak intensity is expected on August 13, shortly before dawn, when you could count dozens of shooting stars per hour , maybe even hundreds, of average brightness and the brightest.
" Unlike last year - said Gianluca Masi, an astrophysicist at the Planetarium of Rome and head of the Virtual Telescope - the peak will fall at night and by day, the Moon also virtually absent, not yet in the first quarter, will not bring any interference with its shining .

This year there will be a very rare astronomical coincidence: in these evenings of August, at sunset, you can see - looking west - Venus, Mars and Saturn form a small triangle in the sky. On 12 and 13 August, the twilight meeting, say the experts of the National Institute for Astrophysics (INAF), will see the entrance on the scene of a fourth host, a sickle moon in its crescent phase. The celestial show Aug. 12 will do so as a prelude to the maximum intensity of the meteor swarm.

The classic advice is to go into poorly lit areas, preferably on the slopes, look to the east in the direction of the constellation Perseus which the Perseids get their name because the wakes light appear to come from a period (the so-called radiant) located in the constellation Perseus. If you want to fully enjoy the show, however, will better focus the observations in the second part of the night when the phenomenon appears more visible because the radiant is higher in the sky and Earth appear to meet the swarm of dust particles left along its orbit of comet Swift Tuttle.

Like every year, for the night of the shooting stars were organized demonstrations and evenings observing throughout Italy. The most famous is certainly
Goblets of Stars scheduled August 10, an initiative of City Wine and Wine Tourism Movement in collaboration with the Italian Amateur Astronomers Union. The
Lipu will open during the night 6 oasis and reserves, with guided tours and observations by amateur astronomers.
Nights banner of the stars falling in some WWF, national parks and museums such as the Belluno Dolomites National Park and the Town Museum which will open to the public observatory of Monte Zugna.
