Type 1a supernovae are extremely consistent astronomical events used as standard candles.
State the peak absolute magnitude of a typical Type 1a supernova and describe the characteristic shape of its light curve, referencing the typical timescale in days.
The Triangulum Galaxy (M33) is approximately 8.4×105 pc8.4 \times 10^5\text{ pc}8.4×105 pc from Earth. Deduce whether a Type 1a supernova that occurs in this galaxy can be observed from Earth with the naked eye, assuming a naked-eye limiting magnitude of +6.0+6.0+6.0.
