Carbon and nitrogen on Earth could appear after collision with another planet

A cosmic collision after which the Moon has separated from the Earth has left on our planet essential chemical elements to the fault. The life sciences have come to this conclusion.

The shock occurred about 4.4 billion years ago, and the wandering mass of the planet since Mars has struck the Earth, throwing rock fragments into space, and the Moon's natural satellite was formed, The Guardian wrote.

Scientists believe that In addition to the formation of a new celestial body in a cosmic accident, it would have resulted in another consequence. In particular, the carbon and nitrogen of the wandering planet, now part of organic compounds, have landed on the earth.

The petrologists of the University of Texas at Rice University came to this conclusion after a series of experiments on geochemical reactions at high temperatures and pressures occurring in the bowels of our planet. They wanted to understand how the Earth was getting the key chemicals: meteorites, or perhaps other ancient sources.

The head of the research team, Demmandirl Grewl, discovered that a planet with a rich sulfur core should have large amounts of carbon and nitrogen at the same time. area. The core of the Earth, probably, is iron and nickel. Thus, a planet with a sulfur core could transmit these volatile elements of the Earth in the right proportions if it collapsed. The researchers came to this conclusion through computer simulation of many solar system development scenarios, comparing the results to what it actually looks like. 19659005] "In exploring primitive meteorites, scientists have long since discovered that the Earth and other solid planets in the inner circle of the solar system are devoid of volatile substances, but the time and mechanism to obtain these volatile elements for a long time. long period gave rise to heated controversy, "said scientist Rajjip Dasgupta.

"The scenario we propose is the first that can explain the period and the means to base them on geochemical evidence," added the director. he is.
