Double-detonation supernova could explain why the universe is full of candles
SMRTR summary
A white dwarf supernova 160,000 light-years away has provided evidence of a double-detonation explosion. This discovery could explain why there are more "standard candle" supernovae than expected, which astronomers use to measure the universe's expansion. The observation suggests helium ignition triggered an early eruption before reaching the typical mass limit for white dwarf explosions.
