the study said.<\/p>\n<p>The team said they found 23 different types of amino acid while examining the sample collected by Japan&#8217;s Hayabusa-2 probe in 2019.<\/p>\n<p>The dust and rocks were stirred up when the fridge-sized spacecraft fired an &#8220;impactor&#8221; into the asteroid.<\/p>\n<p>&#8220;The Ryugu sample has the most primitive characteristics of any natural sample available to mankind, including meteorites,&#8221; the Japan Aerospace Exploration Agency (JAXA) said in a statement.<\/p>\n<p>It is believed that part of the material was created about five million years after the birth of the solar system and has not been heated above 100 degrees Celsius (210 degrees Fahrenheit).<\/p>\n<p>Another study published in the US-based journal <i><a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a><\/i> said the material has &#8220;a chemical composition that more closely resembles the Sun&#8217;s photosphere than other natural samples&#8221;.<\/p>\n<p>Kensei Kobayashi, an astrobiology expert and professor emeritus at Yokohama National University, hailed the discovery.<\/p>\n<p>&#8220;Scientists have been questioning how organic matter\u2014including amino acids\u2014was created or where it came from, and the fact that amino acids were discovered in the sample offers a reason to think that amino acids were brought to Earth from outer space,&#8221; he told AFP.<\/p>\n<p>Another mainstream theory about the origin of amino acids is that they were created in Earth&#8217;s primitive atmosphere through lightning strikes, for example, after Earth cooled down.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            What h<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp;
