Scientists discover most brightest and energetic supernova yet
... the Institute of Gravitational Wave Astronomy at the University of Birmingham, is lead author of the study. He explains: "We can measure supernovae using two scales—the total energy of the explosion, and the amount of that energy that is emitted...

Oldest known superluminous supernova discovered
... given a large enough sample, scientists could then be able to 'standardise' them as they did with type 1a supernovae. Type 1a supernovae are exploding white dwarf stars and are used in cosmology as typical "standard candles" for measuring the...

Will Betelgeuse go supernova soon? Probably not say some astronomers
...of this luminous giant. Its unusual behaviour has prompted some to speculate that Betelgeuse is on the verge of going supernova; a transformational rebirth event, that given the mass of the star (Betelgeuse is between 8 and 17 times as massive as our...

Did two ancient supernovas cause cell mutation and climate change on Earth?
... to be very little effect at all," he said. "The supernovae were pretty far way – more than 300 light years – that... only at high altitude." The research suggests that the supernovae might have caused a 20-fold increase in irradiation by muons – ...

Astronomers catch a supernova shock wave in visible light for the first time
...several weeks or months. However the maximum intensity of a supernova explosion occurs after the shock wave and it is this... of these results," said Garnavich. "You look at two supernovae and see two different things. That's maximum diversity." In ...
