Make Betelgeuse looks as observed.

The star is near dying and expelling gas and dust until it start making iron and goes boom.
Since Elite happens in the 3000 and Betelgeuse is still around, it means it is still fluctuating and releasing gas.
I have no idea if Frontier will have Betelgeuse go Super Nova as part of an event or not, but I think the effort should be made to make it look as we currently knows it looks like.
