An ‘exploding star’ has totally baffled astronomers by repeatedly going supernova (core material ejection) and not diminishing then dying. iPTF14hl exploded 5 times over 2 years.
It’s the astronomical equivalent of a horror film adversary: a star that just wouldn’t stay dead. When most stars go supernova, they die in a single blast, but astronomers have found a star that survived not one, but five separate explosions. The “zombie” star kept erupting for nearly two years – six times longer than the duration of a typical supernova.
‘Zombie’ star survived going supernova
Amazingly in a Gravity Universe the stars brightness varied by about 50% yet is temperature remained constant at 5,700 Centigrade. Yet a supernova, a stellar explosion in its core, is supposedly a plasma star shedding chemical elements and plasma. How can its temperature energy remain constant with these gigantic releases of energetic material?
Normally supernovae will shine brightly for about 4 months and then fade away.
“This supernova breaks everything we thought we knew about how they work. It’s the biggest puzzle I’ve encountered in almost a decade of studying stellar explosions,” said co-author Iair Arcavi, a postdoctoral fellow at Las Cumbres Observatory (LCO) who is based in California.
… “As of now, no detailed model has been published that can explain the observed emission and constant temperature of iPTF14hls, let alone the possible eruption 60 years ago,” he wrote. “For now, the supernova offers astronomers their greatest thrill: something they do not understand.”
‘Zombie’ star survived going supernova
Electric Universe stars should be able to increase and decrease their physical properties, using electromagnetic plasma phenomena to keep being a star.

Intriguing a supernova was observed in the same area and the exact same location in 1954. Was this the same plasma stars explosion and it survived all this time before coming out of retirement again and happening once more in 2017?
Every supernova so far observed has been considered to be the terminal explosion of a star. Moreover, all supernovae with absorption
lines in their spectra show those lines decreasing in velocity over time, as the ejecta expand and thin, revealing slower-moving material that was previously hidden. In addition, every supernova that exhibits the absorption lines of hydrogen has one main light-curve peak,
or a plateau in luminosity, lasting approximately 100 days before declining. Here we report observations of iPTF14hls, an event that
has spectra identical to a hydrogen-rich core-collapse supernova, but characteristics that differ extensively from those of known
supernovae. The light curve has at least five peaks and remains bright for more than 600days; the absorption lines show little to no decrease in velocity; and the radius of the line-forming region is more than an order of magnitude bigger than the radius of the photosphere derived from the continuum emission.
Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Is this mystery supernova explained and the result of being an electric star? The dusty plasma observed around supernovas being a significant EU theory smoking gun or smoking star in this case.
