iPTF14hls is an unusual supernova star that erupted continuously for about 1,000 days beginning in September 2014 [2] before becoming a remnant nebula. [3] It had previously erupted in 1954. [ 4 ] None of the theories nor proposed hypotheses fully explain all the aspects of the object.
It would arise when a star "in the transitional range (~8 to 10 solar masses) between white dwarf formation and iron core-collapse supernovae", and with a degenerate O+Ne+Mg core, [137] imploded after its core ran out of nuclear fuel, causing gravity to compress the electrons in the star's core into their atomic nuclei, [138] [139] leading to a ...
Type Ia supernova progenitors are white dwarf stars that are close to the Chandrasekhar limit of about 1.44 solar masses and are accreting matter from a binary companion star. The list includes massive Wolf–Rayet stars, which may become Type Ib/Ic supernovae, particularly oxygen-sequence (Wolf-Rayet WO) stars.
Stanley Tucci has been a professional actor for nearly 40 years. He’s earned three Emmy Awards, been nominated for an Oscar and a Tony, held his own with Meryl Streep twice and stolen scenes in ...
In 2015, scientists thought they witnessed the brightest supernova ever recorded, but it turns out it might have been an even more rare event — a black hole ripping a star to shreds.
The supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole, based on current stellar evolution models. The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy. [3] By 22 May 2023, SN 2023ixf had brightened to about ...

With Supernova 1987A, the star's size and the neutrino burst's duration had suggested the remnant would be a neutron star, but this had not been confirmed through direct evidence.
