The international group of astronomers first recorded the earliest stage of the formation of rocky planets around the young star. This has given scientists a unique opportunity to see how our own planetary system could be started more than 4.5 billion years ago. The work was published in Nature magazine.
The subject of the study was the HOPS-315 pre-star, the yellow dwarf in the formation process, the age of which is estimated only 100-200 thousand years. It is located about 1370 light years from the country, the direction of Orion constellation.
With the help of James Web's space telescope and Alma radio interferometer, scientists were able to study the gas and dust disk around the star and found hot mineral particles, silicate crystals and molecules of siliccy oxide. These are these materials, according to modern concepts, have become the first solid "construction blocks" of the sun's planets.
The observations showed that the active zone of minerals is located about where in our solar system, the asteroid zone between Mars and Jupiter is located. In the past, such a process could not be registered outside the solar system. It was unknown at this time what he will do after leaving the post.
Astronomers plan to search for other similar objects to understand how popular the scenario of worlds of the world is prevalent.
"We want to know whether we are alone or the Earth's born in the universe much more often than we think," said Merel Van Toff researcher at the University of Perdu.
