supernova

Using deep observations from the VLT's FORS2 instrument, they looked for a bright supernova.

They emit enormous amounts of radiation, continuously lose material through stellar winds and eventually end their lives in supernova explosions.

That amount of energy is comparable to the output of several billion supernova explosions, the powerful blasts produced when certain stars reach the ends of their lives.

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.

Such a binary is called a nova and has quite a different origin from a supernova.

It measures how fast distant galaxies are moving away from our home galaxy, the Milky Way, by observing the brightness of supernovae explosions in these far away galaxies.

Type Ia supernovae are known to be “standard candles” because we know that their luminosity is the same wherever they are.

However, the South Korean study published last year challenged it by arguing that Type Ia supernovae did not all reach the same peak brightness as the universe aged.

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.

And there, when the skies are clear and the Moon not too bright, he finds his supernovae.

"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.

Instead of treating these stellar explosions as having one standard brightness, they adjusted for the ages of the galaxies they came from and worked out how bright the supernovas really were.

Neutron stars are the smallest, most dense stars known to exist and are formed when massive stars explode in supernovas.

From Science Daily ● Apr. 26, 2024

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

But unlike Hubble’s dim Cepheids, supernovas are visible halfway across the universe.
