Scientists found small salt grains in an asteroid sample come from space

When scientists can find evidence of water presence in space, what is salt! Researchers have discovered a Christian of salt (sodium chloride) in an asteroid sample brought by a Japanese spacraft on the earth. Hayabusa Mission, Japan, collected a sample in 2005 from Estroid Etokawa. The sample was brought to Earth in 2010. After analysis of this, the cries of salt that has been found, looks the same as that of the salt used in the house.

This is the first of its kind Research Is, which suggests that the cristed of the salt on the earth came from its parent sectroid. Etocaawa is an S-Type of Estroid. Such meteors and sectors have been found on the earth in the east.

Last year, a study also revealed that water on the earth could have come from Estroid. Researchers had concluded this after examining the samples brought by Estroid Ryugu to Earth. These samples were also collected by Japan’s Spacecraft Hayabusa -2 (Hayabusa -2).

Researchers believe that the Earth is built in the inner region of solar nebula, where the temperature was very high. This means that water on the earth was to come from the outskirts of the solar nebula, where the temperature would have been low. Scientists believe that the comet and sectroid outside the solar nebula collide with the earth to deliver the water.

The samples in which the researchers discovered salt ie sadium chloride are a dust particle, which has a Vyas 150 micrometer. It is twice the width of human hair. The team investigated a small part of this particle which was only 5 microns wide.

Researchers denied that the sample must have been contaminated in any way. Scientists tested the sample well before starting research. He was safe for 5 years. Scientists have come to the conclusion that the salt they have received in the sample belongs to Etokawa.
