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).

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.
