Astronomers have, for the first time, detected radio waves from a Type Ia supernova, uncovering new clues about white dwarf explosions and their helium-rich environments. For the first time, astronomers have observed radio waves emitted by a Type Ia supernova, a type of explosion originating from

This provides important clues to understand how white dwarfs explode.is the nuclear explosion of a white dwarf star.
Artist impression of the double star system with a compact white dwarf star accreting matter from a helium-rich donor companion, surrounded by dense and dusty circumstellar material. It was the interaction of the exploded star and the material left over from this companion that gave rise to the strong radio signal and the conspicuous helium lines in the optical spectra of SN 2020eyj.
