I read that
Betelgeuse Mass 14 M☉ Radius 630 R☉
and
"Aldebaran Mass 2.5/0.15 M☉Radius 25 / 0.04 R☉"
Is this same as 16 M 625 R???????

Both Red Giants and Betelgeuse is likely to go nova soon or already
have i read in Wikipedia.

What stage of redgiant is Aldebaran why would it be more unlikely to
go nova?
It is only 65 lightyear away is that why it is more unlikely go
Nova ;) ?

Also i wonder about the etymology of the word Aldebaran means
apparently follower in Arabic
How come it to be an fallen angel in the book of Enoch.

Is there any evidence to support that red giants going novas in old
days was considered demons or called fallen angels.

Speculation on my part
I am thinking of St George defeating the dragon (draconis) och Mithra
defeating the bull (Taurus)
Is there any signs of any supernovas during christian time in Draconis
and during persian time in Taurus?

Sorry, I can't make any sense of that. Some units or definitions appear
to be missing: could you quote your source more fully?

I doubt there's any direct relation, except perhaps that a Hebrew word
might have a common etymology with the Arabic; the languages are
related. The name Aldebaran is supposed to come from _Na'ir al-Dabaran_,
"Bright One of the Follower", the lunar mansion including Alpha Tauri
and the Hyades, immediately west of -- i.e. "following" -- that of the
Pleiades. Aldebaran usually rises less than an hour after M45, and if
the Moon is in conjunction with the cluster one night, it'll pass the
star at about the same time the following night.

It is Wikipedia, i think the numbers is just distance and solar masses
compared to earth sun, what numbers do you miss?

Both have run out of hydrogen fuel, so i assumed since the radius and
size seems to be the same that they are in same state of development,
is this wrong?

I also wonder if we can detect from earth from what direction in the
sky where most radiation and particles leak through? I know that our
magnetosphere probably shield us from most of it but there is still
some particles and getting through right?

Where is Aldebaran located in the night sky at 00.00 i live in sweden
should i look north south east west? Is it easily spotted?

I did see that pioneer 10 was heading towards Aldebaran, do you know
what parts of the sky the neutrino labs taking data from can they
measure ELF?
