Almost eleven years ago and already, using the network . “Op” refers to the snake-bearing galaxy Opioids, and IRS to the source. As Futura explained in an article, today we are recreating the content somewhat. Observations made using (Very large telescope) இன் ‘ Showed before the alma that we are in the presence of a disk drilled by a central hole created by an invisible planet. Estimated to be ten times If it is not another star.Alma (Atacama large millimeter / sub millimeter array) In Chile, Brought forward The OP-IRS 48 star is located at about 444 From In
Subsequent observations of the Alma revealed that the radio astronomers were replacing the expected ring. Then stopped in the laboratory From Marseille () And by his colleague Then from the Geophysical and Industrial Flows Laboratory at Grenoble () This model suggests Giant gases are responsible for capturing and absorbing the dust on the disk It orbits the star, forming with such efficiency And planets are also possible. It assumes the presence of anticyclonic loops, capable of surviving without being disconnected by disk rotation.It soon became clear that there was unprecedented observational evidence in a model presented in 1995.

Off-IRS 48 and Exobiology
Today is the opposite It is plagued by new observations made with Alma, so back to Op-IRS 48. As explained in an Eso newsletter, and published in the accompanying article Researchers at the Leiden Laboratory in the Netherlands were behind the new discovery. Was identified on a protoplanetary disk and, in addition, is organic because it contains methoxymethane with the CH formula3OCH3.
However, it turns out that this molecule is the precursor that allows the origin Large sizes that can be used for the appearance of life. We already know about the existence of this molecule and others Inside Molecules as we know them are surrounded by protoplanetary disks. But this is the first time that this molecule has been shown to be found on such a disk. Capable of producing and developing life forms similar to those we know on Earth.Of
” Thanks to these results, we can learn more about the origin of life on our planet, so we can get a better idea of the possibilities for life on other planetary systems. It will be very interesting to see how these results fit into the bigger picture. Nashanty Brunken, a postgraduate student at Leiden Observatory and lead author of the published study, explains:
In fact, it is expected to be operational in the coming years), In Korean In Chile, the astronomical chemistry studies of the disk around OP-IRS 48 allowed it to move more precisely into its interior. Can appear.(

Prebiotic molecules in ice
Decades ago, the astronomical chemistry study of molecular and dusty clouds by radio astronomers was astonishing. In addition to hydrogen molecules and silicate and carbonaceous dusts, more than 120 simple organic molecules have been found there. TheThese astronomical chemistry and observational data suggest that dust is surrounded by water ice, which includes these simple molecules. (Collar ‘ (NH3), Methane (CH4), Methanol (CH3O), The (H.2CO) or Formic acid (HCOOH) reacts with each other under the action of photons. Young stars born in these clouds.
We know that carbonaceous meteorites contain organic molecules From And Especially. But meteorites formed from dust in molecular clouds. So there is an integer Prebiotic is the ability to stabilize the appearance of life on rocky outcrops To the protoplanetary disks that form from these clouds.
Recently, however, it was shown that the dust trap discovered by Alma on Oph-IRS 48 contained precisely the ice-covered dust, and it was in this area that Alma’s observations revealed the presence of the methoxymethane molecule.

Therefore, we understand the statements of Alice Booth, a researcher at Leiden Labs and co – author of the published article: ” What makes this discovery even more exciting is that we now know that these large, complex molecules are available to the energy planets that form on the disk. It was not previously known because in most systems these molecules are hidden in ice “.
We also understand what his colleague Nyonke van der Marrell said: “ We are very happy that the complete path of these complex molecules, from star-forming clouds to comets, is beginning to pass through disk-forming disks. We hope that we can get closer to understanding the origin of molecules through further observationsIn our own solar system “.
