When stars inter into the red giant stage from the main-sequence stage, supergiant stars can form. The zone of hydrogen burning expands the star outward leaving an inert helium core. This outward movement causes hydrogen fusion in the outer shell of the star making the star thousands of times larger.

The duration of the Supernova TV series can vary depending on the specific season or episode. Generally, each episode of Supernova lasts around 45 minutes to an hour. The total duration of the entire series will depend on the number of seasons and episodes produced.

Supernovas are formed in two main ways. First, in a binary star system, when one star becomes a white dwarf and accretes matter from its companion, it can reach a critical mass and undergo a thermonuclear explosion, creating a Type Ia supernova. Second, in a massive star, once nuclear fusion in its core stops, the core collapses under gravity and then rebounds, resulting in a massive explosion and the formation of a Type II supernova.

There is no candy bar named "Supernova." It is possible that you may be referring to a limited edition or regional exclusive candy bar that is not widely available.

No, a supernova did not directly kill the dinosaurs. The most widely accepted theory is that dinosaurs were wiped out by an asteroid impact that caused massive climate disturbances, including a nuclear winter-like effect, which led to their extinction. Supernovae are extremely powerful explosions of dying stars that release immense amounts of energy, but there is no evidence linking a supernova event to the extinction of the dinosaurs.

Both supernovae and black holes are extremely powerful and destructive cosmic phenomena, but in terms of their potential impact on surrounding objects, black holes are generally considered more destructive. A supernova is the explosive death of a massive star, which releases a tremendous amount of energy and can have far-reaching effects in its vicinity. However, black holes have an intense gravitational pull that can devour nearby matter, including stars and even entire galaxies, making them more destructive in terms of their ability to consume and destroy surrounding objects.

The Little Boy atomic bomb dropped on Hiroshima exploded with an energy of about 15 kilotons of TNT (~6 × 10^13 joules)

During the Cold War, the United States developed hydrogen bombs with a maximum theoretical yield of 25 megatons (~10^15 Joules)

A Supernova releases as much energy as the Sun emits in it's entire life or 1044 joules

which is about ten octillion megatons of TNT (~10^28 joules)

So you'd need about 10 trillon (~10^13) of the most powerful hydrogen bombs to equal a supernova.

The most powerful hydrogen bomb was the Tsar Bomb created by the Soviet Union. It was designed to output over 100 megatons of TNT but was reduced to 50 megatons in order to reduce fall out.

Tycho's supernova which he saw in Casseopia was important, as its suddenness and brightness caused him to study astromomy for the rest of his life. That resulted in many contributions to the modern understanding of stellar objects.

The Sun does not have enough mass to become a supernova because its mass is less than the Chandrasekhar mass (approximately 1.4 Suns) and it has no way to gain mass.

When the Sun comes to the end of its life (In about 5 billion years) [See Link] it will slowly emerge into a red giant. The dying Sun will then throw off its outer layers, forming a nebula. The only object remaining will be the extremely hot core, which will slowly cool and then fade as a white dwarf over many billions of years.

Interestingly, the fact that our solar system contains heavy elements indicates that supernovae have occurred here before. Our sun is probably the third star to exist in this cosmic neighbourhood, and our solar system formed from the particles left over from prior stars destroying themselves in spectacular manner

Very. Hundreds to millions of times the solar output, squeezed into a few seconds. A supernova at one of our closest neighbors would end all life on Earth.... not maybe from the blast, but at least from retaining heat from our own Sun.

By looking for them. Either by telescope or sometimes, with the naked eye. They are one of the most luminous objects in the sky emitting as much energy as our Sun does in it's entire lifetime.

It depends on the mass of the star. When massive stars die the result is usually an enormous explosion called a supernova, but the core will collapse to form a dense remnant. If the remnant is less than 3 times the mass of the sun then it will form a neutron star. If it is greater than 3 times the mass of the sun it will form a black hole. Extremely massive stars may collapse directly into a black hole with no supernova.

Nobody really knows. However we do know that is a spherical object - not an oblate spheroid - about the size of Manhattan (about 12km in diameter) with a very smooth surface. Smoother than anything on Earth.

A young one will be very hot, and it will have a massive gravitation density.

A supernova occurs when a high mass star dies and becomes a neutron star. As the core collapses because fusion burns out and radiation pressure can no longer hold it up, then degenerate electron pressure can not hold it up, the electrons are forced into the nucleus and combine with protons to form neutrons, the strong force causes the nuclei to merge into one ball of neutrons: a neutron star. The surface of the neutron star is very hard and as additional matter from the original star continues to fall in and merge into the neutron star, a "traffic jam" occurs and the shockwave resulting from this reflects off the super hard surface of the neutron star, driving the supernova explosion. Suddenly everything falling in is now rushing out. This can only occur once.

Supernovae release vast quantities of radiation. However, the impact on planets of nearby stars without life is probably long-term negligible... rocks aren't affected all that much by radiation anyway.

That is not currently known for sure. Check the Wikipedia article on "Ultra-high energy cosmic rays" for different explanations about how they MIGHT be caused.

Any stars less massive than our sun do not explode in a supernova. They will slowly cool down and burn out forming an "ember" (a.k.a. white dwarf).

Supernovas [See Link] are classified according to the absorption lines of different chemical elements that appear in their spectra. The classification can be simplified to Type I or Type II Type II - If a supernova's spectrum contains a line of hydrogen in the visual portion of the spectrum. Type I - all the rest. These are broken down even further. Type:- Ia - When a white dwarf merges with another star. Ib & Ic are formed by massive stars running out of fuel but have lost the outer layer of hydrogen and helium like Wolf-Rayet stars Type II are the "normal" types of supernova, where massive stars can no longer maintain hydrostatic equilibrium and the core collapses IIP Reaches a "plateau" in its light curve IIL Displays a "linear" decrease in its light curve Supernova [See Link] classifications are based on chemical composition.

When its original source of fuel has run out for instance our sun runs on hydrogen, after the depletion of the original fuel is gone the suns core condenses creating helium were the star expands to great measures were it gets to a size were its limited supply of helium runs out either collapsing into a black hole or a dwarf star

The remnant core of a star that becomes a supernova will normally be a neutron star, or possibly a pulsar (a rapidly spinning neutron star). The largest of stars would theoretically create a black hole, a singularity containing all of the core's mass at a single point and preventing even light from escaping its massive gravity.

Massive Stars.

Betelgeuse will be a Type II Supernova.
