Stellar Kablooey

Scientists have observed a supermassive star dying in a previously unobserved type of double explosion. It appears the star, in the galaxy UGC4904 (78 million light years away in the Lynx constellation), was about 50 to 100 times the mass of the Sun, and generated at least two massive explosions in its death throes. The discovery has implications which could change the way we model star birth and death.
