Stellar 'events'

TML message #5228From bundle 445

	I recall that in a not so recent Challenge  there was a report that
the star Antares stands a decent chance of going supernova in the next 250 years
  What exactly would that DO?  How far would a mass 14 lum 16 star like that
wreck?   There is a red giant about 6 ly away from Antares  would that be pushed
into doing anything?
	Basically have any of you guys got info on Novae, sub-nova events,
super novae and the effects of stellar flares?
  Big list I know ! :)
Thanks

PS.....    Gravity and Gravity waves....?   'how fast does gravity go?'
if there is such a thing as a gravity wave  could someone tell me what they
do and how fast they go?
