Oldest known superluminous supernova discovered
... and 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...

Astronomers catch a supernova shock wave in visible light for the first time
... astrophysics professor at the University of Notre Dame in Indiana who led the analysis efforts. These types of supernovae are known as Type II supernovae and occur when a massive star runs out of nuclear fuel causing its core to collapse as gravity...

Astronomers spot fastest stars in the galaxy with Gaia
... these leftover stellar remnants. White dwarfs are also behind one of the most common types of supernova explosions in the local Universe - Type Ia supernovae (SNe Ia). SNe Ia occur when mass from one star is transferred onto a white dwarf companion...

New research questions the rate at which the Universe is expanding
... on this standard cosmological model as new data has become available. The data relates to studies on a type of exploding star known as a Type 1a supernova. Type 1as involve two stars, one of which is a white dwarf – the one that will explode - and...

Gigantic remnant found around an exploding star
... leave 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...

Will Betelgeuse go supernova soon? Probably not say some astronomers
.... Its supergiant status already earmarks it as a variable-type star; a star that regularly brightens and dims with generally... to speculate that Betelgeuse is on the verge of going supernova; a transformational rebirth event, that given the mass of the...
