A cosmic murder mystery: Scientists spot supernova of star violently stripped to the bone

Israeli and American scientists have uncovered a never-before-seen type of supernova, shedding light on how stars produce and expel heavy elements like silicon and sulfur during their violent deaths.

Artist’s drawing of SN 2021yfj. Having lost its outer layers, the dying star was left with only a core of oxygen, sulfur and silicon (bright center dot) but continued to experience extreme mass loss episodes that led to the ejection of material rich in silicon (gray), sulfur, and argon.
