Astronomers have found a giant ring of life bricks near a distant star.

MOSCOW, June 29 Astronomers have found a giant ring of complex organic molecules in the vicinity of an unusual triple-star embryo in the constellation Ophiuchus revolving around yet unborn luminaries at about the same distance as Pluto from the Sun, according to an article published in the Astrophysical Journal. the movement of gas containing organic matter, using the Doppler effect, how spectral lines stretch and shrink as a result of the movement of gas in our or in the opposite direction, we find that it rotates and that it is spin precession is a sufficiently compact ring. His discovery suggests that organic matter accumulates in the disk from which the planets later form, said Yoko Oya from the University of Tokyo (Japan). Oia and her colleagues made this discovery by watching one of the closest and most unusual ‘germs ‘stars triple system IRAS 16293 2422, located just 446 light years from Earth. Today, it is a large cloud of gas, within which a pair of two embryos of stars orbiting each other at a short distance dwells, and a third future star circling around them at a distance 10 times further than Pluto is distant from the Sun.

This gas cloud and the germs of stars are too cold to see with optical telescopes, and therefore scientists use the most powerful microwave radio telescopes to see the glowing embers of the luminaries forming and the surrounding gas and dust. Relatively recently, the first ‘cosmic’ sugar was found in this gas and dust disk, which showed that such building blocks of life can exist in the vicinity of newborn stars. Japanese scientists who watched IRAS 16293 2422 using the most powerful radio telescope ALMA, added to the number of unusual features of this system and extremely a bizarre ring of organic matter, which is located on the border between its protoplanetary disk and a dense cloud of gas surrounding the ‘cocoon’, where three stars of this system are formed.

This ring, as shown by the observations of Oya and her colleagues, contains a whole range of complex organic molecules, including the methyl formate compound of formic acid and methane, as well as sulfide carbonyl compounds of sulfur, oxygen and carbon.

Scientists explain that they are formed in an interstellar medium, far from the destructive rays of stars, on the surface and in thickness of ice and dust. that are emitted into open space by flashes of supernovae. The observations of IRAS 16293 2422 show that they accumulate at the interface between the protoplanetary disk and the surrounding gas, probably as a result of the destruction of these grains during collisions with other particles of stellar building materials and the action of centrifugal forces. A similar process, as scientists believe today, could saturate the embryo of the Solar System with organic matter and prepare it for ‘delivery’ to the future Earth using the first comets and asteroids that bombarded our planet during the first days of its life. The discovery of a “living example” of such transportation in the form of IRAS 16293 2422 speaks in favor of the fact that this is exactly what happens, the scientists conclude.
