what is the difference between a supernova explosion and a nova explosion?
4749
A nova is an explosion from the surface of a white-dwarf star in a binary star system. ... A supernova is a violent stellar explosion that can shine as brightly as an entire galaxy of billions of normal stars. Astronomers divide supernovae into two groups: Type I and Type II.

Risk by supernova type Although they would be spectacular to look at, were these "predictable" supernovae to occur, they are thought to have little potential to affect Earth. It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth's ozone layer.

The generally accepted difference is one of formation; stars are said to have formed from the "top down", out of the gases in a nebula as they underwent gravitational collapse, and thus would be composed almost entirely of hydrogen and helium, while planets are said to have formed from the "bottom up", from the ...

A neutron star merger is a type of stellar collision. It occurs in a fashion similar to the rare brand of type Ia supernovae resulting from merging white dwarfs. When two neutron stars orbit each other closely, they spiral inward as time passes due to gravitational radiation.

Fire is caused is when a substance rapidly consumes oxygen to produce heat and light. An explosion is an event where energy rapidly expands outward from the source, often creating a damaging shock wave. A fire may not cause an explosion, and explosions can happen without fire.

Star is normally big cloud of very hot gas (plasma) emitting light. Meteor is visible path made of gloving plasma caused by meteoroid entering atmosphere. They both emit light, they are both made from plasma but there similarity ends.

The Short Answer: A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. A nebula is a giant cloud of dust and gas in space.

Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.

One of the major difference between the Avalanche and the Zener breakdown is that the Avalanche breakdown occurs because of the collision of the electrons, whereas the Zener breakdown occurs because of the high electric field. The other differences between them are explained below in the comparison chart.

As verbs the difference between hit and bang is that hit is to administer a blow to while bang is to make sudden loud noises, and often repeatedly, especially by exploding or hitting something.

A nova occurs when enough hydrogen accumulates at the white dwarf's surface to undergo spontaneous fusion. A type Ia supernova is the result of the white dwarf's total mass exceeding the Chandrasekhar limit, at which point gravitational pressure exceeds the electron degeneracy pressure within the white dwarf.

As verbs the difference between explode and implode is that explode is to destroy with an explosion while implode is to collapse or burst inward violently.

A type I supernova occurs in closed binary systems where two average stars orbit around each other quite closely. ... A large amount ofd the white dwarf's material fuses in a short period of time the star explodes. A type II supernova occurs in larger stars of around 10 solar masses.

A main sequence star that lacks the mass necessary to explode in a supernova will become a white dwarf, a 'dead' star that has burned through all of its hydrogen and helium fuel. ... No longer emitting heat or light, the white dwarf will become a black dwarf. Because it emits no radiation, it is nearly impossible to see.

And because luminosity decreases with distance, scientists can use the difference between an explosion's observed and predicted brightness to determine how far away the blazing starstuff is. That characteristic has led to type 1a supernovae being called “cosmic mile markers” and “standard candles.”

In both cases the singularity was a single point where the curvature of space time are infinite. ... Therefore, the main difference is that a black hole singularity is the end of space time (and pulls matter in) and the big bang singularity is the beginning of space time (where matter and space were made 'real').

Neutron stars are significantly more dense than white dwarfs which themselves are significantly more dense than normal matter on earth. ... -Nova is a smaller explosion out of hydrogen that leaves white dwarfs intact. -X-ray burster is a neutron star that has x-ray bursts. How are nova formed?
