<p>This is another interesting item found on the Fediverse.  It seems Betelgeuse is still active.  It does appear that there are different ideas as to why this is happening</p>

<p>If Betelgeuse does go Super Nova then this activity may give clues to how stars can behave before hand, giving indications to future events that can be studied more closely perhaps.</p>

<p>I have added a discourse link in case anyone would like to comment further generally.</p>

<p>I have downloaded the paper for this, from Nature Communications.</p>
