US EditionAstronomers Capture First Direct Image of Double-Detonation Supernova Remnant
- In July 2025, astronomers published in Nature Astronomy the first visual evidence of a double-detonation supernova in the supernova remnant SNR 0509-67.5 in the Large Magellanic Cloud.
- Scientists discovered the first visual evidence of a double-detonation supernova in SNR 0509-67.5, confirming long-standing suspicions due to the predicted calcium fingerprint.
- Using ESO’s VLT MUSE instrument, scientists identified two concentric calcium rings in supernova remnant SNR 0509-67.5, confirming a double explosion, as published in Nature Astronomy.
- This discovery shows white dwarfs can explode early, refining Type Ia supernova use for measuring universe expansion.
- In future models, this discovery may revise stellar evolution theories and help resolve the Hubble constant tension impacting cosmological measurements.

WDC TV NewsA star exploded twice — First-ever image reveals its cosmic fingerprint
Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a second, core-shattering explosion.
