Almost eleven years ago and indeed, using the network . “Oph” refers to the serpent-bearing constellation Ophiuchus, while IRS refers to the source As Futura explained in an article that we are partially reproducing today. Notes made using (very large telescope) From’ Before Alma, we were in the presence of a disk perforated with a central hole, probably formed by an invisible planet Estimated ten times Unless it’s another star.Alma (Large Atacama Group Millimeter / Meter) in Chile, brought to the fore From the star Oph-IRS 48 located at about 444 The In the
Later ALMA observations then revealed instead of the ring that radio astronomers expected to see Then stationed in a laboratory from Marseille () And by his colleague Then from the Laboratory of Geophysical and Industrial Flows in Grenoble (). This model indicates that Giant gases are responsible for capturing and containing the dust in the disk that surrounds the star, so efficiently in the formation of Even planets will become possible. He postulates the existence of anti-vortex vortices, which are the only vortices capable of surviving without being ruptured by the rotation of the disk.Which soon turned out to be most likely observational evidence that was lacking so far in the model that was introduced in 1995 by

Of-IRS 48 & External Biology
Today is rather which is influenced by the new observations made with Alma and thus again Oph-IRS 48. As described in a press release from Eso, and as evidenced by the accompanying article published in researchers from the Leiden Observatory in the Netherlands were the ones behind the new discovery, which is the biggest discovery It is identified in a protoplanetary disk, plus it is organic because it is methoxymethane with the formula CH3OCH3.
However, this molecule has been shown to be a precursor allowing to appear in Larger sizes can be used for a life look. We already knew about the existence of this molecule and the molecule associated with it at We know that stars are born surrounded by protoplanetary disks. But this is the first time that it has been demonstrated that this molecule can also be found in such a disc, and therefore it is also likely to be present in Able to give birth and develop life forms similar to those we know on Earth.From
” Thanks to these results, we can learn more about the origin of life on our planet, and thus have a better idea of the potential for life in other planetary systems. It is interesting to see how these results fit into the bigger picture. Moreover, in this regard, Nashanti Bronken, a master’s student at the Leiden Observatory and lead author of the published study, said in the Eso press release.
In fact, it is expected in the coming years to start running), in Korean In Chile, let’s go further in the astrochemical studies of the disk around Oph-IRS 48 and more precisely in its interior, where can appear.(

Prebiotic molecules in ice
Decades ago, radio astronomers demonstrated that studying the astrochemistry of molecular clouds and dust was amazing. In addition to hydrogen, silicate and carbonic dust particles, more than 120 simple organic molecules have been detected there. TheFrom this astrochemistry and observational data indicate that the dust is surrounded by a slice of water ice where these simple particles, such as (collar’ (NH3) and methane (CH .)4) and methanol (CH .)3oh (h2CO) or Formic acid (HCOOH), formed and reacted with each other under the influence of photons Young stars are born in these clouds.
We know that carbonaceous meteorites contain organic molecules that can be considered From and the Especially. But meteorites formed from dust in molecular clouds. So there are all Prebiotics that could determine the appearance of life on rocky exoplanets ranging from to the protoplanetary disks that consist of these clouds.
However, it was recently shown that the dust trap previously detected at Oph-IRS 48 by ALMA contains fine dust surrounded by ice and in this region ALMA’s observations revealed the presence of the methoxymethane molecule.

So we understand the statements of Alice Booth, also a researcher at the Leiden Observatory and co-author of the published article: What makes this discovery even more exciting is that we now know that these larger, more complex particles are available to power planets forming in the disk. This was not previously known because in most systems these particles are hidden in the ice “.
We also understand what his colleague Nienke van der Marel said: “ We are very excited to be able to begin tracing the full path of these complex particles, from the clouds that form stars to comets, through to the disks that form the planets. We hope that with more observations, we can come closer to understanding the origin of moleculesin our solar system “.
