Discovering the signs of old stars from the solar system in an asteroid – | Iranian and world news

The findings published in three articles show how Ben No. has saved clues about the early period of the Solar System, according to . Pierre Hancur from the University of Arizona, who analyzes examples of pre -solar seeds and is one of the authors of the research, says: It is interesting that Ben Nou is like a time capsule of materials that existed throughout the solar system at the beginning of its formation.

The NASA’s Osseris Rex’s spacecraft landed on Ben Noo in the year 6, and collected the samples containing dust particles in the Solar System, organic materials of inter -planetary space, and the dust of old stars of the sun.

Researchers believe that these small particles are likely to travel many distances before reaching the asteroid of Ben No. This larger asteroid has been collapsed for millions of years in the asteroid belt between Mars and the customer.

“We see the example of the asteroid bin, the remnants of the materials that originally existed throughout the Solar System,” says Henkur. Some of these seeds have gone through intense heat, reaction with water, as well as many collisions, which include catastrophic collision that led to the collapse of the mother’s asteroid.

One of the research published in the Nature Nature Astronomical magazine shows that the ice inside the mother’s asteroid has melted and reacted with dust. This reaction has led to the formation of minerals that now make up about 2 percent of the asteroid. Some particles, such as silicone carbide, have unique chemical symptoms that reveal the type of stars they come from, but these stars are no longer exist.

“They have been lost long ago,” he says. We cannot observe stars that belong to certain grains.

These very small and often smaller micrometer particles are identified with abnormal chemical effects caused by nuclear reactions in their maternal stars. Mapping of these particles is like search for needle in the straw warehouse, but allows researchers to track the ancient origin of Ben Noor’s constituents.
