Depending on what the bursts» waveforms look like, how loud the bursts are, how frequent they are and how they correlate with the
supernovae as seen with electromagnetic telescopes, the data could help to validate or discard various, existing models.
No further bursts were
seen in 90 hours of additional observations, which implies that it was a singular event such
as a
supernova or coalescence of relativistic objects.
Hollingshead mentions the
supernova and says what a spectacular sight it was, so even if the memory — the actual memory of
seeing it when he was eight years old in 1572 was fading, but, you know,
as an adult he has a chance to be reminded of just how incredible that thing was.
Some cosmic rays detected on Earth are produced in violent events such

supernova explosion SNR 0509 - 68.7 — also known

supernova explosion hurled this stellar corpse from the blast site, leaving behind a glowing trail, which is still

as the handle of the frying pan.
Also, he points out, if there is a huge population of stars outside galaxies, we should
see a noticeable number of
supernovas occurring out in the middle of nowhere
as those rogues stars die.

The Core - collapse
Supernova Rate Problem, or the fact that we don't
see as many core - collapse
supernovae as we would expect, has a solution, thanks to research using the Gemini South telescope.
An international team of astronomers, led by PhD student Erik Kool of Macquarie University in Australia, used laser guide star imaging on the Gemini South telescope to study why we don't
see as many of these core - collapse
supernovae as expected.

Eventually, they explode
as supernovae (

originate from fusion reactions in the heart of stars and are spewed out when those stars explode
as supernovae, the relatively high metallicity of the galaxy suggests that it had already
seen the birth and death of generations of stars by the time the universe was 700 million years old.»
The Crab Nebula, one of the most famous nebulae and
seen here by the Hubble Space Telescope, is actually the expanding explosion of a core collapse
