“Moving rocks” is an unexplained phenomenon that happens in the desert Mojave, region located between Nevada and California.

More precisely, it is possible to observe Playa Racetrack, in the famous Death Valley, United States national park full of geological history, where is the biggest depression of North America (-86 meters below sea level).

In this sandy desert, probably the..

Canneto of Caronia – the strange episodes of spontaneous fires

tecnics — Thu, 10 Dec 2009 00:11:53 +0000

The strange episodes of Canneto di Caronia - spontaneous fires in houses, vegetation, abnormal flow of electromagnetic energy, sightings of Ovni - do not end up in oblivion. It appears that within a reasonable period of time (at a guess by the end of 2009) will restore those monitors that a couple of years ago had been suspended, creating a..

Stellarium – Virtual Planetarium

Max — Tue, 17 Nov 2009 09:39:44 +0000

Stellarium is a software project that allows the user to use your PC as a virtual planetarium. E 'can calculate the position of the sun, moon, planets and stars, and play in the sky as they would appear to an observer at a given place and at any given time.

It can also draw the constellations and simulate astronomical phenomena such as meteor showers, eclipses of the Sun and Moon. Stellarium can be used as an educational tool for teaching the starry sky at night..

NASA – found water on the moon

tecnics — Sat, 14 Nov 2009 18:02:38 +0000

Today, NASA has opened a new chapter in our understanding of the moon. Preliminary data from the Lunar Crater Observation and Sensing Satellite, or LCROSS, indicates that the mission has found water on impact in the region of permanently shadowed Cabeus October 9, 2009, near the lunar south pole.

The impact resulting from LCROSS Centaurupper stage..

What are Thunderstorms and Lightning?

Max — Tue, 26 May 2009 23:57:14 +0000

What is Thunder?

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..

Hubble retires

Max — Wed, 06 May 2009 11:36:56 +0000

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..

Earthquakes

Max — Mon, 04 May 2009 13:10:17 +0000

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...

The Cassini spacecraft – an adventure in evolving

Max — Tue, 07 Apr 2009 13:00:37 +0000

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..
