New type of supernova discovered by astronomers

(CNN)Astronomers have discovered a new type of supernova, or star explosion, and it provides a new window into the violent life cycle of stars. The new research, focused on supernova 2018zd, confirms a prediction made by University of Tokyo astronomer Ken'ichi Nomoto more than 40 years ago....

...Typically, supernovae occur in two flavors. During a core-collapse supernova, a massive star (more than 10 times the mass of our sun) exhausts its fuel and the star's core caves in to a black hole or a dense remnant called a neutron star. The other type is called a thermonuclear supernova, and it occurs when a low-mass star remnant called a white dwarf -- usually less than eight times the mass of our sun -- explodes after pulling matter from a companion star into itself. But what happens to star between eight and 10 solar masses, such as the star involved in supernova 2018zd? They explode a little differently....

There's a cool little blurb in the article about the Crab Nebula being visible in the sky in 1054 for 2 years.

One picking point. The article describes a white dwarf having a mass of 8 solar masses, while the Chandrasekhar limit places the maximum at 1.4 solar masses.

Is it a Champagne Supernova?

(or ‘Supernover’ as the Brothers Gallagher pronounced it) :P

Astronomy / Cosmology is proven racist and all of their practitioners must undergo re-education for the removal of these racist terms! White Dwarfs and Black Holes must be renamed as they reek of White Patrimony!

Yes, SARCASM BUT any bets that this is not percolating in those various pressure groups?

Yes. It was documented extensively in China.

The difference is just a few more sticks of dynamite.
