Over the next few million years, this cloud began to flatten, forming a donut-shaped ring or torus with a budding star gathering mass at its core.

But the new study suggests that gravity had major assistance from magnetism. The signature of this additional cosmic artist was found within grains of dust sealed in DOM 08006, a <a href=\"https:\/\/www.space.com\/42636-meteorites.html\"><u>meteorite<\/u><\/a> recovered from Antarctica in 2008. <\/p><iframe src=\"https:\/\/content.jwplatform.com\/players\/Nx3J7j8Q.html\" id=\"Nx3J7j8Q\" title=\"Formation of Planets in a Protoplanetary Disk | Video\" width=\"600\" height=\"338\" frameborder=\"0\" scrolling=\"auto\" allowfullscreen><\/iframe><p>The grains found by the team are calcium-aluminum-rich inclusions (CAIs), which are thought to have formed during the first 200,000 years of the solar system. That potentially makes them the oldest samples of solar system material ever seen.<\/p><p>\"We know they are the oldest things we have of the early solar system,\" team leader Cau\u00ea Borlina of Purdue University <a href=\"https:\/\/news.mit.edu\/2026\/meteorite-dust-holds-records-magnetism-may-have-helped-form-sun-0824\" ><u>said in a statement.<\/u><\/a> \"But CAIs are very complex and are not all the same, even within a 1-millimeter piece of the meteorite. So we have to carefully identify what types they are.\"<\/p><p>These CAIs indicated that there was a magnetic field in the proto-solar system even during its solar nebula phase. This magnetic field would have been stronger than <a href=\"https:\/\/www.space.com\/earths-magnetic-field-explained\"><u>Earth's magnetosphere<\/u><\/a> and, as such, would have influenced the flattening of the solar nebula.<\/p><p>\"This transition, from a spherical cloud to a protoplanetary disk, is one of the most significant events in all of solar system history,\" team member Benjamin Weiss, of the Massachusetts Institute of Technology (MIT), said in the same statement. \"It has long been theorized that gravity caused this, but our measurements show magnetism likely played a role.\"<\/p><h2 id=\"a-new-spin-on-early-solar-system-magnetism\">A new spin on early solar system magnetism<\/h2><p>In the newly forming solar system, a magnetic field would have been generated when charged particles were sent spinning through the collapsing cloud of gas and dust that birthed <a href=\"https:\/\/www.space.com\/58-the-sun-formation-facts-and-characteristics.html\"><u>the sun<\/u><\/a>. This plasma would then have sustained that field.<\/p><p>As such, that magnetism must have affected the material in the solar nebula that would become the solar system. For that reason, the team reasoned that the strength of this field should be \"locked in\" to materials from the time as remanent magnetization. This matter could make its way to <a href=\"https:\/\/www.space.com\/54-earth-history-composition-and-atmosphere.html\"><u>Earth<\/u><\/a> in meteorites. <br><br>In fact, the same scientists who conducted this research previously found evidence of a magnetic field that existed 2 million years into the formation of the solar system, baked into meteorites. That's an impressive and important find, because this magnetic field would have helped planets like Earth form  \u2014 but the sun was already around by that point. Thus, the team was after an earlier magnetic field, one that predated our star.<\/p><p>\"Nowadays, people don\u2019t debate whether magnetism is present when planets are forming. But the debate is around the very early solar system, before planets are forming, when there\u2019s just a disk,\" Borlina said. \"That's where the debate still resides, and that\u2019s where we\u2019re operating now.\"<\/p><figure class=\"van-image-figure  inline-layout\" data-bordeaux-image-check ><div class='image-full-width-wrapper'><div class='image-widthsetter' style=\"max-width:2000px;\"><p class=\"vanilla-image-block\" style=\"padding-top:56.25%;\"><img id=\"rz6TfNdQqCFff8egVFAdWH\" name=\"Untitled design - 2026-09-01T153349.635\" alt=\"Early solar system material takes shape under the influence of magnetism\" src=\"https:\/\/cdn.mos.cms.futurecdn.net\/rz6TfNdQqCFff8egVFAdWH.png\" mos=\"\" align=\"middle\" fullscreen=\"\" width=\"2000\" height=\"1125\" attribution=\"\" endorsement=\"\" class=\"inline\"><\/p><\/div><\/div><figcaption itemprop=\"caption description\" class=\" inline-layout\"><span class=\"caption-text\">Early solar system material takes shape under the influence of magnetism. <\/span><span class=\"credit\" itemprop=\"copyrightHolder\">(Image credit: Hernan Canellas)<\/span><\/figcaption><\/figure><p>DOM 08006 is one of the most unspoiled or \"primitive\" meteorites ever discovered, retaining and preserving materials, including CAIs, as they were when the sun was forming. <\/p><p>\"Other meteorites went through many different processes over this <a href=\"https:\/\/www.space.com\/24854-how-old-is-earth.html\"><u>4.5 billion-year history<\/u><\/a>,\" said Weiss. \"They were formed in the solar nebula, then added to bodies with water, then got destroyed, moved to the <a href=\"https:\/\/www.space.com\/16105-asteroid-belt.html\"><u>asteroid belt<\/u><\/a>, and then landed here.
