How are supernovas created? This is the issue that a recent study published in Nature aims to address as a team of researchers looks at how recent radio wave emissions have not only helped astronomers pinpoint the origin of a Type Ia supernova, known as SN 2020eyj, but also that its white dwarf companion, from which the exploding star was feeding, was rich in helium. Because of the uncertainty surrounding the processes underlying their explosive nature, this discovery has the potential to aid astronomers in understanding the production and evolution of Type Ia supernovae.A white dwarf binary system in which the left star is feeding off the right star until the left star bursts is depicted in an artist’s rendering.
