Astronomy.com - Strengthening the case for dark energy: type Ia supernovae are uniform after all - "The research group argues that type Ia supernovae explode asymmetrically, and that the different spectral appearance is merely a consequence of the random directions from which a supernova is observed. This result is good news for cosmology because it suggests that the spectral diversity is no longer a major concern in using type Ia supernovae as cosmological standard candles."
