Novas

The largest stars end their lives as black holes. These are regions in space with incredibly strong gravitational forces that can trap even light.

No one knows for sure, since there is not enough information to figure it out. After a supernova, the star will either turn into a black hole, a neutron star, or a pulsar. But, there is no scientific evidence that proves which one the star will turn into after a supernova.

A nova star can appear in various colors depending on its temperature. In general, they can appear white or bluish-white in color when they are at their hottest phase.

An electron degenerate gas in a white dwarf is a state of matter where electrons are densely packed together, leading to a high degeneracy pressure that supports the white dwarf against the inward pull of gravity. This degenerate gas behaves differently from a classical gas and is characterized by the Pauli exclusion principle, which prevents two electrons from occupying the same quantum state.

Our sun is to small to go super nova.Super nova's happen when a star explodes. For a super nova, the star has to be atleast 5x bigger then our sun.When our sun explodes, you would just see HUGE FIREWORKS.

Gamma rays from a supernova can travel vast distances, potentially out to light-years away from the source. They can be detected by astronomers on Earth using specialized instruments, giving us valuable insights into the explosion and its aftermath.

You might find a white dwarf and a red giant in a binary star system. A binary star system consists of two stars that orbit around a common center of mass. White dwarfs and red giants are common types of stars in the later stages of stellar evolution.

The rapid collapse of the star compresses atoms together and may cause nuclear fusion and make heavier elements.

The four elements theory is an ancient concept that suggests the world is composed of four fundamental elements: earth, fire, water, and air. These elements are believed to represent the essential building blocks of all matter and energy in the universe. It is a philosophical framework that has been used in various cultures and traditions to explain the nature of existence and balance in the natural world.

The mass of the remaining core of a star that has exploded as a supernova. (Although some stars can collapse directly to a black hole without a supernova explosion)

If the mass exceeds about 3 to 4 solar masses the degeneracy pressure of neutrons is insufficient to stop the collapse, and the object will inevitably collapse into a black hole.

See related link for more information.

The most common reason why you might not see a supernova would be if it occured on the other side of the Milky Way galaxy. The dense gas and dust clouds in the galaxy make it impossible to see what's on the other side.

The nearest other stars apart from the sun are light years away, so this seems very unlikely, and how could the effects be controlled? == It could be argued that the black hole has already imploded. It is a point of infinite density. How much more imploded can it get? Certainly it would make a great weapon if you could "launch" it at a stellar system you wanted to obliterate. As regards making a star go supernova, only a given type of star does that, and only then at the end of its life. If you could somehow cause this specific type star to exhaust all its nuclear fuel and reach a "mostly iron" stage very, very quickly, you could do that. But how could you speed up nucleosynthesis? And what about other stars? You might be able to get something like a supernova, but it would take some doing. The trick might be to somehow cause the star to begin to collapse in on itself (compress it) and continue to do so until it was greately compressed and continuing to try to burn fuel, then "let it go" from whatever force you had used to cause it to collapse or undergo compression and permit the star to "spring back" to a new form. It would doubtless release huge quantities of plasma, but it would not match the energy release (and the destructive power) of an actual supernova. You may be able to make a weapon by finding a way to just "blow up" a star and throw all that plasma out across the stellar system. It is difficult to imagine how anything would survive something like that. The effect on the planets would be like putting them in a pizza oven - one set at a few tens of thousands of degrees.

The star is likely a giant or supergiant star, which are larger and brighter than main sequence stars like our Sun. These stars have exhausted their core hydrogen fuel and expanded in size. Examples include Betelgeuse and Rigel in the Orion constellation.

The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.

Stars are measured in brilliance called magnitude. The faintest stars visible to the naked eye are mag.6. Brighter ones are mag. 1 or 2, the even brighter stars have negative magnitude.

So its like a number line in math: Brighter Fainter

-6_-5_-4_-3_-2_-1__0__1_2_3_4_5_6

Venus has been observed by humans for thousands of years. It is one of the brightest objects in the night sky and can often be seen with the naked eye. The earliest recorded observations of Venus date back to ancient civilizations such as the Babylonians and the ancient Greeks.

There are a lot of answer out there but there been great research about our sun going Nova. First of all Our sun is too small to become a black hole, second of all our sun can't go through the phase of super nova as our sun is too small. It can only go through Nova. If the sun where to go out right now Life would end instancely well not quite it takes 6 minutes for light to travel to earth from the sun. Our sun is not going go out now but if it did all life would end and our earth would be sucked into the sun. http://www.space.com/scienceastronomy/solarsystem/death_of_earth_000224.html "The life-giving, aging star we orbit is using up its fuel supply and will collapse within 7 billion years. Before that, though, there will be an agonizing period of repeated swelling, as the sun grows into a red giant. How giant? "Earth will end up in the sun, vaporizing and blending its material with that of the sun," said Iowa State University's Lee Anne Willson"

Dwarfism is only expressed when both genes in the persons genome (that determines the trait) are of the dwarf type. Both parents can carry one 'dwarf' gene and one 'normal' gene and express a phenotype of normal. Their children can be either pure normal, half normal, or pure dwarf, with only the pure dwarf expressing the phenotype of dwarf.

The chances of being half normal are 1/2, the chances of being pure (normal or dwarf) are both 1/4.

The $P \dot{P}$ diagram is used to follow the lives of pulsars, playing a role similar to the HR diagram for ordinary stars. It encodes a large amount of information about the pulsar population and its properties. Using the parameters, one can estimate the pulsar age, magnetic field and spin down power. [See Link]

The core collapse of a massive star comences as the core has finished fusing the rest of its fuel into iron, the last and heaviest element forged in high-mass stars. At this point the risidual energy put out by the fusing of elements is not worth the energy it takes to fuse them together. Since the fusion process is no longer being carried out, the thermal radiation that is being created by thermonuclear fusion in the core is no longer available and cannot continue to push outward in the opposite direction of the force of gravity, so the impending collapse is triggered then by the ultimate win-out of gravity against the star's internal forces.

I don't know, but I'd like to give them a good flogging. I read somewhere that the word has been around for centuries, but I don't believe it. I think its a silly made-up word that is simply not necessary. There are plenty of good words that work in place of doable: possible, feasible, workable, achievable, etc.

Seeing as how the general public uses only a small fraction of the words in the English language, I see no need to constantly manufacture new words. But I guess making up words is doable, whereas learning existing words is not.

I know where it came from. I hired a learning disabled kid to help me just to help him out in the job market and went out of business subsequently after he started saying "do-able"

Years later he had a girlfriend and a job with the significant boost he got from me and told me they had diagnosed him as epileptic and that was the reason for his previous squalor.

I would say definitely the word has not been around for centuries and only started being circulated when people passed the buck about helping that kid out and it started in 1994.

Same thing with the "segway" someone sitting next to me in a Jaycees GMM asked me if they could have my permission to create a new word. I didn't give them that permission. Instead I said "well, that depends on what it is." She created it anyway and it was entirely unsuccessful. It was character assasination because my business was an oriental grocery store and segmentation of the market was ruined by being associated with a group like the Jaycees.

When people do things in your behalf with your express objection then it is unsuccessful and not possible and will come back to where it started with no progress being made.

There is no set limit. It all depends on the amount of light being emitted by the observed object. Looking out in space on a clear new-moon-night the nake eye can see stars that are LIGHT YEARS away. However, on relatively flat ground here on Earth, the nake eye can see for about 8-10 miles until the curvature of the planet makes the land "disappear" from view.
