Seems reasonable from the standpoint of heating, but how about radiation
(and particles, which one might assume are ejected from a super-nova at
something close to c)?  Even with the diameter of the Earth for protection,
is there enough dust around us for back-scatter to do us in quickly?  And
what if the moon is full (well, Larry Niven[?] may have covered that one)?

Just looking on the bright side...
