Supernova nucleosynthesis refers to the production of new chemical elements inside supernovae. It occurs primarily due to a neutron capture process known as the r process.
Supernovae
At large distances (up to about 1 billion light-years), astronomers can no longer use methods such as parallax or Cepheid variables.
Supernova Type Ib
Originally lumped in with Type Ia (SNIa) and Type Ic (SNIc) supernovae due to the similar appearance of their light curves, Type Ib supernovae (SNIb) were recognised as a separate class in the mid-1980s.

Supernova
Modern era are named by the year of their discovery and given a capital letter from the alphabet to mark the order in which they were discovered in that year. SN is used as the abbreviation for supernova.
Supernovas tienen duración de uno o dos años, y durante este lapso de tiempo, pueden brillar mucho más que una galaxia entera. Lo que ocurra con la estrella después de la supernova dependerá de cuán grande era.
A supernova can briefly outshine the rest of the galaxy it is a part of.
They occur about once every two hundred years per galaxy, and ones within our galaxy (but not too close!) can usually be seen by the naked eye, often even during the day.
SUPERNOVA 1987a
This Hubble Space Telescope image shows the remnant of a supernova a star that blew itself to pieces. We first saw the light of the explosion on Earth in 1987, and this image was taken in 1994.

Wear safety glasses throughout this activity. The devices used in this experiment to power the gas- filled tubes use a very high voltage of electricity.
A supernova is the explosive end of a star's life. The power of the event is almost more than one can imagine.

Supernovas
A supernova explosion is far more spectacular and destructive than a nova and much rarer.
Supernovae
Sanduleak -69° 202 was a blue supergiant with a mass of about 18 solar masses in the Large Magellanic Cloud. When it exploded as Supernova 1987A it captured the attention of astronomers from around the world.
SUPERNOVA REMNANTS
We have plenty of evidence that supernovae have occurred in our Galaxy. Occasionally, the explosions themselves are visible from Earth (see Interlude 21-2).
Supernovae. Type I (population II) supernovae can be recognized (and divided into subgroups a,b, and maybe c) based on their spectra and light curves.

supernova
The death explosion of a massive star, resulting in a sharp increase in brightness followed by a gradual fading. At peak light output, supernova explosions can outshine a galaxy.
Supernova Type I
The explosion of a star believed to be caused by mass transfer to a white dwarf.
Supernova Type II ...
Supernova. The outburst of a star on a tremendous scale. There are broadly 2 types of supernova. (1). Where a white dwarf member of a binary system explodes, or matter falls onto the white dwarf and explodes. (2).
SUPERNOVA - Stellar explosion that expels much or all of the stellar material with great force, driving a blast wave into the surrounding space, and leaving a supernova remnant.
supernova (type II): The explosion of a star, believed caused by the collapse of a massive star.
supernova remnant: The expanding shell of gas marking the site of a supernova explosion.
Supernova - An explosion in which a star's brightness temporarily increases by as much as 1 billion times. Type I supernovas are caused by the rapid fusion of carbon and oxygen within a white dwarf.

Type 1a Supernovae
The standard candle of choice in cosmological studies is the type 1a supernova. It is as bright as any event in the universe, so it can be seen in the most distant galaxies.
Supernova SN1987A: the beginning of a supernova.
The repulsive electrical forces between the atoms' nuclei overcomes the gravitational forces, causing a massive, bright, short-lived explosion called a supernova.
Supernovae come in two broad categories, known as Type I and Type II, which are defined by the spectrum of the matter that's ejected into space, and by the way the stars brighten and fade.
Supernova (plural = supernovae) The death explosion of a massive star whose core has completely burned out. Supernova explosions can temporarily outshine a galaxy. The outer layers are blasted out in an expanding cloud.

Supernova explosion is extremely violent. The brightness of the star will increase by up to 15 magnitudes. This will be a spectacular astronomical event.

A supernova occurs when a high-mass star reaches the end of its life. When nuclear fusion ceases in the core of the star, the star collapses inward on itself.

Supernova Remnant
An expanding shell of gas ejected at high speeds by a supernova explosion. Supernova remnants are often visible as diffuse gaseous nebulae usually with a shell-like structure. Many resemble "bubbles" in space.
SUPERNOVA
A supernova is a huge explosion that occurs at the end of a mid- to heavy-weight star's life. A supernova releases a tremendous amount of energy, expelling the outer layers of the star and becoming extremely bright.
A supernova explosion is so powerful that for a few days it outshines the light from all the other stars of a galaxy combined. Because of this, it has been possible to observe supernovas in other galaxies from time to time.
A supernova model involving the explosive ignition of carbon in the high-density (108 - 1010 g cm-3), electron-degenerate carbon-oxygen core of a 6±2 - 7±2 M star by the formation and propagation of a detonation wave.

Novae and Supernovae
Nova
Novae follow the transformation of matter from a main sequence star to a white dwarf companion in a binary system such that the mass of the white dwarf remains below the Chandrasekhar limit.
What is a supernova ?
Stars that have managed to suck in enormous amounts of material at birth erupt into life as supergiants. These stars as well as being mammoths burn incredibly fiercely and after a relatively short lifetime will run out of fuel.
