Asteroid 2012 LZ1 not hit the Earth in the next 750 years

2012 LZ1 Asteroid discovered on 10 June by the Siding spiral Observatory in Australia and capable as harmful by the Minor Planet Center, from colliding with the earth at least the next 750 years. The Puerto Rican Observatory Arecibo, which has one of the largest telescopes in the world at 305 meters in diameter, reported that by using the planetary radar system has determined that the orbit of the asteroid LZ1 not placed close enough to earth to collide in the next 7 and a half centuries, Efe reported.

The Earth needs an emergency plan

Earth has skilled five major group extermination events associated with climate changes that have changed the characteristics of the entire planet. An article in the journal Nature, which involved researchers from the National Research Council (CSIC), analyzes the forces that "may be leading" a new change in planetary status and provides possible tools to minimize its consequences.

The exoplanet "closest" to the Earth

The Kepler space mission has exposed the exoplanet, closet to the Earthlike identified so far. Dub Kepler 10b, the planet is unstable (solid) smaller than those found, since the diameter is the same to just 1.4 times the Earth, while its mass is 4.6 times that of Earth.

In attendance can be no illusions, however, about the possibility of life existing in it, because although Kepler 10b orbits a star (Kepler 10) very similar to our Sun, its distance to it is twenty times less than separating the sun Mercury.

Searching from space in the bowels of the Earth

The ESA astronaut Andre Kuipers of creature approved out an research on the ISS that will shed light on conditions in the depths of our planet. In orbit about 400 km height, Geoflow help us understand how the Earth works inside. Extend to a depth of almost 3000 km; the layer is composed of semi-solid materials graceful slowly under the thin outer shell. For study, it is considered that the mantle is divided into several layers of different viscosity as a result of increased pressure and temperature with depth.

Enlarge the probability of an asteroid crash with Earth

Scientists at the Cardiff Centre of Astrobiology, UK, have developed a mathematical model that confirms that currently is experience our solar system called the extensive hydroplane, which increase the chances of an asteroid collide with Earth. An asteroid is a rocky body that orbits the Sun Becomes meteorite when it enters Earth's atmosphere. In astronomy, is called the huge hydroplane in the middle of the region in which they are most of the stars of a flattened galaxy, as twist galaxies.

Venus

The second planet Venus in our solar system is the closest to Earth in accumulation and dimension, is nearly round, no substantial destruction. It is the brightest star in the sky after the Sun and the Moon. It is visible after sunset or before departure at no great distance from it, why is only visible during the first hours after sunrise and evening star, or during the last hours before the sunrise as morning star.

The outside of Venus is a real hell, enclosed by a thick fatal cloud cover; temperature is 500 º C, organism responsible greenhouse. This defines it as the planet with the highest temperature of the solar system and also the most volcanic.

Earth Meteorite flies only 14 000 kilometers higher than the Earth's outside

Recently, a newly discovered meteorite, 2012 KT42, flew past Earth at only 14,000 miles above the surface of our planet, so flying within the belt of geosynchronous satellites.

According to the orbit of this asteroid, fortunately there was no danger of collision, despite its proximity to Earth.

Moreover, in any case, due to its small size would probably have disintegrated upon entering our atmosphere.

Higher than Earth Asteroid

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

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

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.

New dynamic sunspot AR1492

Now that is turned facing the Earth, we must be alert to its explosion, by the time of class-C, which emit large amounts of plasma above the solar surface.So, the new sunspot AR1492 is very active. 

The Royal Observatory of Belgium plans to continue producing new C-class flares, and even supports the ability to register M-class explosions.

For now, Earth is under the influence of a solar wind of 400 kilometers per second, with a magnitude of the interplanetary magnetic field of about 3 nT

The fossil footprints of those raindrops were to figure

The rain that fell 2,700 million years ago left its mark. An international team of scientists has analyzed the fossil footprints of those raindrops was to figure out how the early atmosphere of Earth.

"Precise measurements of atmospheric pressure back to 1644, when the Evangelist Torricelli invented the first barometer", tells SINC the researcher Sanjoy M. Som, University of Washington (USA). 

Contrary to popular belief, the results of the study, published this week in Nature, suggest that the atmospheric density bent not current levels. 

A dwarf galaxy that is about 70 million light years from Earth

Most galaxies in the universe are classified into three forms: elliptical, disc-and usually flattened, and irregular spiral arms. That is so strange Leda 074886, a dwarf galaxy that is about 70 million light years from Earth is rectangular or, as astronomers have discovered, like a bright emerald. 

"It's one of those things that just make you smile because it should not exist or, rather, did not expect to exist," says Alsiter Graham (Swinburne University of Technology in Melbourne, Australia), lead researcher. 

70 millionaires expect the end of the world in a luxury bunker

70 millionaires builds a high-class underground Luxury bunker where dozens of rich can swim in the pool or watch movies while Earth succumbs under the effect of disasters or the threat of apocalyptic zombies. What was once a silo 53 meters deep will soon become a hotel armored, armed and luxuriously equipped for those who prefer not to spend the Day of Judgment exposed to all sorts of upheavals in the earth's surface.

Housed within the walls of 3 meters of concrete, the fourteen-story apartment design ultra withstand any disaster, from earthquakes of destructive solar flares, through terrorist attacks, starvation and deadly pandemics. Tenants, a maximum of 70 people, will have everything you need to live like kings.

In 2013 The Earth would be face a Solar Tsunami

An expert Scientist says, “We should prepare for a space storm does not look like a thousand years,". The world is increasingly dependent on electricity, therefore, more vulnerable.The current cycle of the star storms would peak next year. On April 16, the sun emitted a "bubble" the size of Jupiter, another sign of increased violent activity, whose peak is in 2013, hence the solar tsunami forecasts. Experts say that we are not prepared for the damage they cause. 

An object hit the earth

The object had ten kilometers in diameter and scientists have not yet determined exactly whether it was a meteorite or comet, but agree that their average speed was 25 to 30 kilometers per second and left a footprint impact (crater) of approximately 200 kilometers in diameter. 

After impact the earth was plunged into total chaos. Caused large fires occurred due to a temperature of up to 20 thousand degrees Celsius were recorded throughout the Americas, there were earthquakes whose intensities ranged from 14 to 16 degrees Richter and other disturbances that resulted in numerous seismic and volcanic eruptions. In addition, heavy rains were present acidic and formed huge waves, which now are known as tsunami (Japanese word derived from), traveling horizontally at speeds of up to 750 mph and reach between 15 30 meters in height. In the case of the Chicxulub impact has been estimated that the tsunami could have reached heights of 100 to 200 meters, says the geologist José Manuel Gradates Nishimura, investigator assigned to the Program of naturally fractured reservoirs, the Mexican Petroleum Institute (IMP).

The Earth hitting after 35% meteorites enter atmosphere does not break

A small impact crater discovered in the Egyptian desert could change the calculations of risk of impact on our planet, according to a recent study. The Kamil crater, one of the best preserved of those found on the Earth, was discovered in February during a survey of satellite images with Google Earth. It is believed that the crater was formed in the last two thousand years. 

The Italian and Egyptian crater found recently visited and studied the hole 45 meters wide by 16 deep. They also collected thousands of pieces of space rocks scattered in the surrounding desert. Based on the calculations, the team believes that a solid iron meteorite, almost intact, between 5,000 and 10,000 kilos crashed into the desert at speeds in excess of 3.5 kilometers per second.

Sunday 1. April 2012 Asteroid 2012 EG5 passed close to Earth

The asteroid 2012 EG5 pass without risk close to Earth this Sunday, April 1. The projected distance traffic is 230,000 kilometers, i.e. 0.6 times the distance between Earth and Moon. Its estimated diameter is about 48 meters, according to the monitoring program of near-Earth J PL (Jet Propulsion Laboratory) spacecraft. 

Astronomers believe the objects are able to approach within 3.5 times the distance from Earth to the Moon may be altered in their normal course by the gravity of our planet or moon. The asteroid 2012 EG5 traveling speeds of 8.24 km / s. It was initially estimated its closest pass to the April 2 but in the end has been more rapid. It was discovered on March 15. 

An asteroid impact with Earth of Consequences

Geological studies conducted over the last decades have shown us that our planet has undergone a similar meteoric bombardment suffered by the Moon, and even more intense. In fact, due to its greater gravity, the impact rate on Earth is 1.5 times higher than our natural satellite. 

The size range of objects striking bodies is between a few meters to others of several kilometers across, and producing very different effects of different factors: the diameter of the shock, their speed, their density, the place to occur impact either on sea or land, etc.. An example of this was the "Tunguska Event" which little impact (June 30, 1908) has gone unnoticed, because it took place on a spot on the planet virtually underpopulated. What would have happened if the case occurred on an urban or densely populated area? 

A collision with an asteroid 2012 DA14 threat to Earth on February 15, 2013

According to this calculations, the orbit of the asteroid with a diameter of between 40 and 95 meters, cross the Earth orbit. Astronomers have calculated that the February 15, 2013, the asteroid will pass only 26 900 kilometers of our planet, which is lower than the orbits of geostationary satellites (about 35,000 kilometers). A recharcher said that 2012 DA14 "belongs" to the regular type asteroids approaching Earth from behind, then or later, in front of him. 

"These are objects that move from time to time near the Earth in fact, they do not go around the earth, but in a coordinate system with two centers (with the Sun and Earth) will be like to turn around Earth, "he quoted. Now it is impossible to predict what will happen in the encounter with Earth in 2012 DA14. "We have to see it, can be farther from the Earth, then closer, even enough to fall to the ground, with some probability that impact the Earth. 

Solar flare hit the Earth

The particles ejected by the sun in recent days in a flare and a coronal mass ejection, (for its acronym in English) hit Earth's magnetic field after 9:00 pm on Tuesday, the U.S. space agency (NASA .)

Radiation, plasma and other particles came from an ejection type M8.7, the second most intense within the classification of solar events. According to the Climate Prediction Center Space Administration National Oceanic and Atmospheric Administration (NOAA) of United States, the solar flare occurred on Sunday 22 and then produced a CME that made her the strongest radiation storm since September, 2005.The Goddard Space Flight Center NASA predicted that the CME could generate some auroras and perhaps affect the operations of some satellites and communications on shortwave radio, but pose no harm to human health.

Solar flares are directed to Earth

The cloud of charged particles could affect today and satellite navigation and electric power. The largest solar storm in five years is about to shake the Earth's magnetic field.

After going through the day and a half space, a huge cloud of charged particles arrive today and could affect electricity networks, satellite navigation systems and flight of aircraft, especially in regions of the northern hemisphere.

However, the same storm may produce colorful auroras at the poles further away than usual.Scientists said on Wednesday that the storm, which began with a huge solar flare earlier this week, is growing as it moves away from the Sun, rising like a huge soap bubble.
