For comparison, the &amp;quot;40 to 60 Ma after solar system formation&amp;quot; in the new paper [3] discussed here translates into roughly 4.517 +&amp;#x2F;- 0.010 Ga.&lt;p&gt;This new paper agrees almost perfectly with one I was a coauthor on a couple years ago though [4], which also gave an age of 4.51 (+&amp;#x2F;- 0.01) Ga, so maybe we&amp;#x27;re starting to get slightly closer to some consensus.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;doi.org&amp;#x2F;10.1016&amp;#x2F;j.epsl.2019.07.008&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;doi.org&amp;#x2F;10.1016&amp;#x2F;j.epsl.2019.07.008&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.newscientist.com&amp;#x2F;article&amp;#x2F;mg21128265-100-moon-may-be-200-million-years-younger-than-thought&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.newscientist.com&amp;#x2F;article&amp;#x2F;mg21128265-100-moon-may...&lt;/a&gt;&lt;p&gt;[3] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.nature.com&amp;#x2F;articles&amp;#x2F;s41561-019-0398-3&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.nature.com&amp;#x2F;articles&amp;#x2F;s41561-019-0398-3&lt;/a&gt;&lt;p&gt;[4] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;advances.sciencemag.org&amp;#x2F;content&amp;#x2F;3&amp;#x2F;1&amp;#x2F;e1602365&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;advances.sciencemag.org&amp;#x2F;content&amp;#x2F;3&amp;#x2F;1&amp;#x2F;e1602365&lt;/a&gt;</text><parent_chain></parent_chain></comment><story><title>The Moon is older than previously believed</title><url>https://phys.org/news/2019-07-moon-older-previously-believed.html</url></story>
