The storm is an intense convective phenomenon accompanied by strong gusts of wind, heavy rainfall also in character and hail lightning (lightning). The storms can be classified into three main types: heat, terrain and time of heat frontali.I develop when the atmosphere is in unstable conditions conditional on reaching a certain temperature near the ground. Are more likely in hot weather, in the mountains in the afternoon and evening.. Continue reading [..]

The Hubble Space Telescope (HST abbreviated English name from the initials of the Hubble Space Telescope, or just Hubble) is a telescope placed in the outer layers of Earth’s atmosphere, about 600 kilometers altitude, in orbit around the Earth (each orbit takes about 92 minutes). It was launched on April 24, 1990 with the Space Shuttle Discovery as a joint project of NASA and European Space Agency.

The telescope can reach an angular resolution better than 0.1 arcseconds.. Continue reading [..]

These are a clear testimony to the vitality of the earth, certainly all the volcanoes are the most visible effect of the fact that our planet is alive (see the flow of heat) and this is largely due to the movement who suffer from the plates (see plate tectonics) above the mantle.


An earthquake is a sudden vibration of the ground produced by sudden release of energy and that energy is spreading in all directions (like a sphere) in the form of waves. But what is this energy? Well imagine it’s like to have in my hands a stick of wood: if you start to bend it offers a resistance to bending which is expressed in the form of elastic energy, rocks behave the same way: ie if a piece of rock begins to deformed, it will offer some resistance (which changes depending on the type of rock), but when the forces that… Continue reading [..]

Cassini-Huygens mission is an interplanetary robotic joint NASA / ESA / ASI, launched on October 15, 1997, with the task of studying the Saturn system, including its moons and its rings. The probe consists of two elements: the Cassini orbiter from NASA and the ESA Huygens lander. Cassini is the first spacecraft to be entered into the orbit of Saturn, the.. Continue reading [..]
