Inner symphony of the Earth

Internal Structure of the Earth. Thanks to the seismically, we know how to be the interior of our planet, the core at its center, consists especially of iron possibly solid, liquid outer core would, and then the mantle would happen a thin crust.

The Earth: A water planet?

The Earth is the planet of our solar system where almost 70% of it is covered by water that makes up the oceans. This is due to the combination of the profusion of the chemical in the solar system, hydrogen, which is the most abundant element in the universe and oxygen, one of the most common in nuclear reactions that occur within the stars. To this is added that the atmosphere created in the surface conditions temperature and pressure close to the triple point of water,

The Earth

Earth is the third planet in our solar system, fortunate place in the solar system we inhabit. Ours is the only planet in the solar system, enclosed regularly by water, as well as being the only one with an atmosphere is mostly nitrogen and oxygen. His temperature various life suitable for the way we see it, range from -50 ° C to 50 ° C, with an average 22 º C. Water has created a system of movement and erosion unique in the solar system. The planet we populate is a rarity that still cannot find a similar model or in our solar system or other systems that are discovered, so far, which appear unapproachable.

Beyond the Earth Asteroid

This asteroid, discovered recently, passed over our planet early on May 28, 2012, about 350,000 miles.

Yesterday, the asteroid 2012 KP24, flew past Earth at only a tenth of the distance of the Moon.

According to NASA, there was not any danger of collision with Earth, but it was an ideal time for many astronomers and amateurs, who missed the opportunity to photograph this large rock, estimated was about 26 meters.

Sunspot 1429 will point to the Earth

Sunspot 1429, causing intense solar storms that occurred earlier this month, comes back on Thursday in the face of the Sun which is oriented toward the Earth, as reported by the Space Weather Observatory.

Experts have explained that "it is unusual for an active region has been the source of so many and such high solar activity is able to maintain much of its integrity and effective capacity after full rotation of the Sun's far side" of there has been a surprise this 'return'.

In response, the National Oceanic and Atmospheric Administration (NOAA) has begun warning of possible new large flares, which could reach the category M (second strongest), from Thursday. But has appealed to the tranquility and pointed out that "in this new spot around 1429 must be, necessarily, of lower intensity than that experienced before," and indicated that "falls within the current parameters completely normal solar cycle.
