Strange star unlike any seen before, scientists say
... with wind speeds of 16, 000 kilometres per second. This stagerringly fast speed is comparable to the expansion velocities of a supernova ejecta, but winds belonging to material blasted out from a single stellar explosion was ruled out by Oskinova...

Gigantic remnant found around an exploding star
... behind will help identify systems undergoing repeated eruptions and help astronomers determine how many Type Ia supernovae are formed. "They are, in effect, the measuring rods that allow us to map the visible universe," said...

Supernova "Matryoshka" Discovered in Local Group
... varied in size and structure. The reason for the particular concentric effect observed by astronomers is that the supernovae exploded at short intervals (only about 10,000 years between explosions), which makes the explosions almost simultaneous...
