In these cold environments, atoms and simple molecules like carbon monoxide stick to dust grains, forming an ice layer and undergoing chemical reactions, which result in more complex molecules. Researchers <a href=\"https:\/\/arxiv.org\/abs\/2104.08906\">recently discovered<\/a> that the dust trap in the IRS 48 disc is also an ice reservoir, harbouring dust grains covered with this ice rich in complex molecules. It was in this region of the disc that ALMA has now spotted signs of the dimethyl ether molecule: as heating from IRS 48 sublimates the ice into gas, the trapped molecules inherited from the cold clouds are freed and become detectable.<\/p>\n<p dir=\"ltr\" style=\"padding-left: 40px;\">\u201c<em>What makes this even more exciting is that we now know these larger complex molecules are available to feed forming planets in the disc<\/em>,\u201d explains Booth. \u201c<em>This was not known before as in most systems these molecules are hidden in the ice.<\/em>\u201d<\/p>\n<p dir=\"ltr\">The discovery of dimethyl ether suggests that many other complex molecules that are commonly detected in star-forming regions may also be lurking on icy structures in planet-forming discs. These molecules are the precursors of prebiotic molecules such as amino acids and sugars, which are some of the basic building blocks of life.<\/p>\n<p dir=\"ltr\">By studying their formation and evolution, researchers can therefore gain a better understanding of how prebiotic molecules end up on planets, including our own.<\/p>\n<p dir=\"ltr\" style=\"padding-left: 40px;\"><em>\u201cWe are incredibly pleased that we can now start to follow the entire journey of these complex molecules from the clouds that form stars, to planet-forming discs, and to comets. Hopefully with more observations we can get a step closer to understanding the origin of prebiotic molecules in our own Solar System,\u201d<\/em><\/p>\n<p dir=\"ltr\">says Nienke van der Marel, a Leiden Observatory researcher who also participated in the study.<\/p>\n<figure id=\"attachment_24939\" aria-describedby=\"caption-attachment-24939\" style=\"width: 700px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.eso.org\/public\/images\/eso1325d\/\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"24939\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=24939\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2022\/03\/eso1325d1.jpg\" data-orig-size=\"700,546\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;ALMA (ESO\/NAOJ\/NRAO)\/Nienke van&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;Annotated image from the Atacama Large Millimeter\/submillimeter Array (ALMA) showing the dust trap in the disc that surrounds the system Oph-IRS 48.
