supernova

One especially energetic kind of Pop III supernova, called a pair-instability supernova, can eject more than 100 times the Sun's mass in heavy elements during a single explosion.

If that were true, astronomers could have been misreading the supernova data and incorrectly concluding that cosmic expansion was speeding up when it was actually slowing.

Because the evolved supergiant is expected to eventually end its life in a supernova explosion, the dramatic dimming prompted speculation that the star might be preparing to explode.

Scientists initially classified the object as a supernova remnant, but that interpretation became less certain after emissions above 100 TeV were detected.

But a more massive star, left, after its supernova phase, with, say, five times the Sun’s mass, has an even more remarkable fate reserved for it—its gravity will turn it into a black hole.

Their analysis focused on Pantheon+, a dataset containing observations of more than 1,700 Type Ia supernovae.

For a brief period, the energy being released reached roughly 400 billion times the output of Earth's Sun, surpassing even the most powerful supernovae known to astronomers.

Their results showed that PBH-triggered SNe Ia could reproduce several characteristics observed in these supernovae and their remnants.

Earlier superluminous supernovae had occasionally shown one or two bumps, often explained as shock waves colliding with shells of gas surrounding the dying star.

All those recently hatched massive blue- white super-giant stars in Orion are destined in the next few million years to become supernovae, a continuing cosmic fireworks in the constellation of the hunter.

"Our prediction is that we'll see a lot more galactic cosmic radiation... which is from supernovas and is everywhere," versus radiation coming from the Sun, he said.

From Barron's ● Apr. 10, 2026

So, is the theory wrong and heavy elements are produced some other way, or are they only produced in supernovas under certain conditions?

From BBC ● Apr. 12, 2024

Long duration GRBs are caused by supernovas, the point when a massive star reaches the end of its life and explodes into a burst of light.

From Science Daily ● Feb. 29, 2024

Ever since, neutrinos have been detected in the Sun, during supernovas and even in interactions between cosmic rays and the upper atmosphere.

The la supernovas explode in roughly the same way and with the same brightness.
