I assume you&#x27;re talking about UDFy-38135539 (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;UDFy-38135539" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;UDFy-38135539</a>), with a redshift of z=8.6.  It is not 13 Gly away, even though the light detected by Hubble&#x27;s infrared camera was emitted about 13 billion years ago.  Due to the metric expansion of space, the distance to that object is around 32 Gly (9710 Mpc according to <a href="http:&#x2F;&#x2F;www.bo.astro.it&#x2F;~cappi&#x2F;CosmoWidget.html" rel="nofollow">http:&#x2F;&#x2F;www.bo.astro.it&#x2F;~cappi&#x2F;CosmoWidget.html</a>).
