While nearly all of the stars in the Milky Way will one day evolve into white dwarfs—this is the fate that awaits the sun some five billion years in the future—not all of them will explode as Type Ia supernovae. For that to happen, the white dwarf must be a member of a binary star system.

This particular supernova, named SN 2024PI, was discovered by an automated survey in January 2024. The survey covers the entire northern half of the night sky every two days and has cataloged more than 10,000 supernovae.
This NASA/ESA Hubble Space Telescope Picture of the Week features the galaxy LEDA 22057, which is located about 650 million light-years away in the constellation Gemini. Like the subject of a previous Picture of the Week, LEDA 22057 is the site of a supernova explosion.
