Heavyweight Contender - Physical Review Focus article |
| Supernova explosions at the ends of stars' lives produce most of the elements heavier than iron. But theorists have had trouble cooking up models of supernovae that make the heaviest elements in their observed abundances. |

The supernova that just won't fade away - ESA press release |

Astronomy's "Impossible" Supernova? - a Skytonight article |

Hypernova Reveals Hidden Identity As Gamma-Ray Burst |
| An international research team, led by astronomers from the University of Tokyo, Hiroshima University, and the
National Astronomical Observatory of Japan, used the Subaru telescope to obtain the spectrum of SN2003jd, a hypernova unaccompanied by a gamma-ray burst, and found the first evidence that it is a jet-like explosion viewed off-axis.
Hypernovae are hyper-energetic Supernovae that are often associated with gamma-ray bursts. This result provides clear
and firm evidence that all Hypernovae may be associated with gamma-ray bursts, but that gamma-ray bursts are observable
only when jets produced by the hypernova explosion point towards Earth. |

Asymmetric Ashes - ESO Science Release |
| Astronomers are reporting remarkable new findings that shed light on a decade-long debate about one kind of supernovae, the explosions that mark a star's final demise: does the star die in a slow burn or with a fast bang? From their observations, the scientists find that the matter ejected by the explosion shows significant peripheral asymmetry but a nearly spherical interior, most likely implying that the explosion finally propagates at supersonic speed. |

Supernovae are Not Spherical (or round) - Subaru Dissects the Interior of Exploding Stars |
| A research team of astronomers from Tokyo University, Hiroshima University and so on, observed 15 supernovae at 200 or more days after the explosion, using FOCAS at Subaru Telescope. Contrary to the traditional view as spherically symmetric expansion, they revealed that supernovae are commonly asymmetric. |

The Gobbling Dwarf that Exploded: VLT Provides Evidence for Type Ia Supernovae Scenario - ESO science release |
| A unique set of observations, obtained with ESO's VLT, has allowed astronomers to find direct evidence for the material that surrounded a star before it exploded as a Type Ia supernova. This strongly supports the scenario in which the explosion occurred in a system where a white dwarf is fed by a red giant. |

White Dwarf 'Sibling Rivalry' Explodes into Supernova |
| Astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found that a supernova discovered last year was caused by two colliding white dwarf stars. The white dwarfs were siblings orbiting each other. They slowly spiraled inward until they merged, touching off a titanic explosion. CfA observations show the strongest evidence yet of what was, until now, a purely theoretical mechanism for creating a supernova. |
