space icarus now we know what an asteroid hit the earth, the dinosaur extinction, so what is the asteroid position, estimated that many people don't know, but scientists are not sure.To be sure, the diameter of the asteroid at least 10 kilometers, the scar after hitting the earth obviously will not be erased, even after 65 million years of time.In 1991, scientists through remote sensing satellites photographed the mysterious circle, is located in Mexico's Yucatan peninsula, speculated that this was caused by a massive object colliding.It is interesting to note that this mysterious circle unexpectedly in the 600 meters deep underground, hidden under the surface of the earth in ten million, it was not until today are discovered.
shown in the figure, the diameter of the crater about 180 kilometers, half in the sea, is located in the land, half after tens of millions of years of geological change, now we can already see the outline of it.
in April 2016, the scientists determined by further offshore drilling, s located in late cretaceous, the rock record high temperature and high pressure explosion environment, obviously does not accord with the geological evolution.Sichuan icarus tuo space researchers think, impact craters were formed on Mexico's Yucatan peninsula has destroyed all the surrounding land, thousands of kilometers in the forest all down, the earthquake reached more than 10 on the Richter scale.
the impacts of high temperature gas into the atmosphere, the smoke spreading through the equator wind belt to the earth, the sun was blocked out, this scene is a nuclear winter.Scientists through North Dakota K - Pg boundary strata of the study also found, before the rock is the number of vegetation in the forest, and then have no dinosaurs, it shows that the impact caused the dinosaurs.K - Pg boundary layers also known as the cretaceous - paleogene boundary, is the death of the dinosaurs of the line.
scientists believe that Mexico's Yucatan peninsula crater is an accidental collision, such as the dangerous level of near-earth asteroids they will come.Sichuan icarus tuo space researchers think, America's space agency, NASA, has been the implementation of an asteroid deflection current plans, using precise kinetic energy impact to change its orbit, and this is the only way in which the earth life.
