Neutrinos are elementary particles produced in the nuclear furnaces inside stars and in supernova explosions.

Antimatter flits into existence in a variety of ways: it is produced by black holes, supernovas, and some types of radioactive decay.

Supernova explosions of individual stars in our Milky Way galaxy should also produce detectable gravitational waves, which could help astrophysicists figure out exactly how the stars blow up.

It had been thought that heavier elements are forged during supernova explosions, but computer simulations of the process didn't always produce the proportions of these elements seen in nature.

Other cosmic phenomena such as supernovae in the Milky Way and colliding neutron stars in our galactic neighborhood should also produce detectable gravitational waves, each with their own accompanying revolutionary insights, but so far all three of LIGO's detections have been death - rattles from merging pairs of black holes in remote stretches of the universe.

«We are now fully confident that one of the most popular supernova remnants detected in our galaxy was produced by an ordinary type Ia supernova that was first detected more than 400 years ago,» write Andrea Pastorello of Queen's University Belfast and Ferdinando Patat of the European Southern Observatory in Germany in a commentary on the study.

Stars with a few to about 30 times the mass of the Sun are thought to collapse to form neutron stars, producing a supernova in the process.

And then I also thought about the fact that over the history of the life of the universe, neutrinos are not just produced by the sun, but when stars explode in a supernova, the most brilliant fireworks in the universe, as brilliant as those fireworks are, less than 1 percent of the energy of the star is coming out in light; 99 percent is coming out as neutrinos and so neutrinos are being, [and] every time [a star explodes there's] an incredible burst of neutrinos.

The aftermath of the neutron star collision detected in August included the gravitational waves spotted by LIGO and VIRGO (pale arcs); a near - light - speed jet that produced gamma rays (magenta); expanding debris from a kilonova — an explosion similar to a supernova, but smaller — that produced ultraviolet (violet), optical and infrared (blue - white to red) emission; and X-rays (blue).

Some cosmic rays detected on Earth are produced in violent events such as supernovae, but we still don't know the origins of the highest - energy particles, which are the most energetic particles ever seen in nature.

My research is focused on understanding the origin of «stardust» produced in the envelopes of low - mass stars or in supernova explosions, and preserved in carbonaceous meteorites and interplanetary dust particles.

They are thus probably more similar to galaxies in the early Universe when there had been less time for stars to produce the heavy elements and then return them to their surroundings through supernova explosions.

The second process relies on the fact that stars also contain smaller amounts of carbon produced in previous generations of stars that exploded as supernovas.

In any case, any developing carbon - based life on a developing Earth - type planet would be subject to tremendous heat on a newly formed planet that is under intense asteroidal and cometary bombardment, in addition to the intense and deadly radiation produced by nearby supernovae and other massive young starIn any case, any developing carbon - based life on a developing Earth - type planet would be subject to tremendous heat on a newly formed planet that is under intense asteroidal and cometary bombardment, in addition to the intense and deadly radiation produced by nearby supernovae and other massive young starin addition to the intense and deadly radiation produced by nearby supernovae and other massive young stars.

A Type Ic supernova may be produced by a high - mass star that has blown off much of its outer hydrogen layer while still retaining a significant helium layer, and so it is similar to a Type Ib except that helium is seen in its spectrum.

The supernova explosion that produced the Crab pulsar occurred in the year 1054 and was documented by Chinese astronomers.

HEFT will map the hard X-ray emission from supernova remnants to investigate issues of stellar nucleosynthesis (through the mapping of radioactive Titanium) and study the origin and acceleration of cosmic - rays (through mapping the continuum hard X-rays produced in the same shocks that produce the cosmic - rays).

Indeed, GRBs appear to emit produce even more energy than supernovae or even quasars (which are energetically bright accretion disks and bi-polar jets around supermassive black holes that are most commonly found in the active nuclei of some distant galaxies and possibly even in the pre-galaxy period after the Big Bang).

The next step would be to look for presence of Lithium - 7 and Boron - 11 — also produced by neutrino spallation in supernovae — in meteorites.

While other objects in the universe generate cosmic rays, most probably active galactic nuclei located far beyond our own Milky Way galaxy, supernovae in our own galactic neighborhood are thought to produce a large fraction of the cosmic rays that impact Earth.
