❖ Using the James Webb Space Telescope, astronomers discovered SN 2023adsy, the most distant Type Ia supernova detected.

❖ Supernovae (SNe) are powerful and luminous stellar explosions.

❖ Supernovae are generally classified into two groups depending on their atomic spectra.

❖ Type I lack hydrogen in their spectra, and Type II displays hydrogen spectral lines.

❖ Type Ia supernovae (SN Ia) are found in binary systems in which one of the stars is a white dwarf.
