What is the difference between supernovae and nova

As long as it continues to take gas from its companion star, the white dwarf can produce nova outbursts at regular intervals. A supernova is a violent stellar explosion that can shine as brightly as an entire galaxy of billions of normal stars.

If enough gas piles up on the surface of the white dwarf, a runaway thermonuclear explosion blasts the star to bits, leaving nothing behind. Eventually, the star reaches its final stage forming a supernova explosion. Supernovae are the most powerful explosions in the universe. They release a huge amount of energy into space. Also, they eject a vast amount of matter including heavy nuclei. As physicist believe, supernovae are the primary source of heavy nuclei such as Uranium.

Nova : Nova can be categorized based on their light curves. Supernova : Supernova can be categorized based on their spectra. Nova : Nova has several thousand solar luminosities. Supernova : Supernova can outshine an entire galaxy. Nova : Hydrogen nuclei fuse into Helium nuclei. Supernova : Supernovae are the primary sources of heavy nuclei such as Uranium and Silver.

Conjecture, 17 Feb. Differences Between a Nova and a Supernova. Difference Between Similar Terms and Objects. MLA 8 W, Marium. This article is awful. Not only does it get most of the facts wrong, but it is written very poorly and is hard to understand.

Sometimes Novae are so bright they can even be seen during the day. Long ago, Novae and Supernovae were thought to be the same thing: new stars that appeared in the sky, but soon faded.

Stars are massive balls of hydrogen and helium gas with other trace elements thrown in. Stars form when massive clouds of gas and dust in space fall in on themselves because of gravity. Gravity is the result of mass—the more massive something is, the more gravity it exerts.

As a collapsing cloud of gas and dust gains mass it pulls harder and harder on the gas and dust inside, creating a great amount of pressure. As the atoms of hydrogen and helium are forced closer and closer together under this pressure, the star heats up. This is called gravitational heating. Eventually, if the ball of gas is massive enough, the heat and pressure in the center become so great that hydrogen atoms one proton and one electron in the core are jammed together to form helium atoms two protons, two neutrons, two electrons.

This is called nuclear fusion. Nuclear fusion gives off a tremendous amount of radiation, light, and heat, and is the reason stars do not simply cool down after a few million years—fusion replaces the heat lost into space. Gravity pulls material in, and heat tries to force material back out. When the two forces are in balance, meaning the star stays the same size for a long, long time, the star is said to be in hydrostatic equilibrium.

When this happens the star goes through some changes because of the new, greater source of heat. Now, depending on how massive the star is there are several ways this can go: Smaller stars just sort of peter out.

When it is done blowing off these layers, the carbon and oxygen core that is left behind is called a White Dwarf. Really big stars keep fusing heavier and heavier elements together until they reach iron.

It takes too much energy for the heat and pressure in a star to fuse iron into anything heavier. This means that as the iron core of the star gets bigger and makes more iron, the iron chokes the fusion, causing the star to cool. This happens pretty fast, and when it does, the outer parts of the star suddenly are not being held up by heat anymore: The star is out of hydrostatic equilibrium.

The star falls very fast into itself, gaining speed faster than the rising heat and pressure can control. When a star enters the supernova stage, they can emit more energy than what it did during its lifetime. The Crab nebula r M1 in the constellation of Taurus is an example of a supernova remnant.
