Novae and Supernovae Astrophysics Nucleosynthesis and Stellar Evolution Novae and Supernovae Questions Why are pulsars not always associated with supernova remnants? Would you expect to find supernova remnants inside globular clusters? Why? How can we see supernova remnant G1.9+0.3? If it is estimated to be about 25,000 light years away and now NASA says that it is about 140 years old, how can we even observe it? Wouldn't it still appear as a star to us for the next 24,860 years or so? How long do supernova remnants last? How are supernovae detected? What kind of a star goes “nova” (not supernova)? What kind of star is most likely to become a white-dwarf supernova? What happens when a red giant star becomes a white dwarf? Could a novae and a white dwarf supernova occur with a white dwarf that is not a member of a binary star system? Why do novas occur? Could our Sun ever undergo a nova or white dwarf supernova event? Why or why not?
