What specific object holds the record for the most luminous supernova recorded as of its 2015 discovery?
Answer
ASASSN-15lh
ASASSN-15lh was documented in 2015 as the brightest supernova observed, achieving a peak luminosity of approximately $2 imes 10^{45} ext{ erg/s}$, or 570 billion times the luminosity of the Sun.
