How much intrinsically brighter is a typical supernova (magnitude -19) compared to the Sun (magnitude +4.8) based on the standard magnitude scale difference?
Answer
2.5^24 times
A difference of 24 magnitudes in the celestial scale means the supernova is intrinsically brighter by a factor of 2.5 raised to the power of that difference, or 2.5^24.
