The expansion of the Crab is driven by the pulsar wind nebula, rather shockwaves from the initial explosion. Filaments around the edge of the nebula appear to have moved more compared to those in the center, and that rather than stretching out over time, they appear to have simply moved outward.See it in action:https://youtu.be/xsXH2MGIXbI]]></description><link>https://forum.fedi.dk/topic/5632b6c9-5799-48a2-b4df-eed0c28e0118/hubble-released-a-new-image-of-the-crab-nebula</link><guid isPermaLink="true">https://forum.fedi.dk/topic/5632b6c9-5799-48a2-b4df-eed0c28e0118/hubble-released-a-new-image-of-the-crab-nebula</guid><dc:creator><![CDATA[kellylepo@scicomm.xyz]]></dc:creator><pubDate>Invalid Date</pubDate></item></channel></rss>
