New evidence of a large cold spot partly causing dimming of Betelgeuse
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
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.
I have added a discourse link in case anyone would like to comment further generally.
I have downloaded the paper for this, from Nature Communications.
