I'm sure this has been spotted more than once before, but it was novel to me.
There's often been debate about the group of Sathanas juggernaughts that remained behind to be destroyed by the supernova instead of jumping away. This group of ships goes black shortly before the event and is apparently vaporized.
Some have suggested that these ships simply lost power due to some kind of equipment failure. But it appears they actually made a choice to remain behind, and that this was a voluntary and necessary part of the supernova process.
As the other juggernaughts disengage their green-ripply-weapons and jump away, you can see that the Sathanas juggernaughts in question are still maintaining their own green ripply spheroid things. Perhaps they're completing the final step of the supernova; perhaps they're a safety mechanism to make
completely sure everything goes well.
It appears that these ships weren't left behind by accident. It was -- perhaps -- an intentional part of the process. Very interesting.
Also, it draws an interesting parallel to the endings in which Alpha 1 chooses to remain behind.
