Life Cycle Of Supernova Stars

Orion has two of the brightest stars, be Betelgeuse and Rigel. Betelgeuse is a red supergiant. The gravity of the star squeezes its core tightly, heating it to billions of degrees. It then fuses the helium to make heavier elements. When that happens, the star no longer produces energy in the core. Without the reactions in its core to push outward, gravity quickly causes the core to collapse, forming a neutron star.

According to scientists we have at least 5-6 million years before the sun would ever die out or explode. However if a phenominon like that were to occur there are diffent theories to what might happen. It would take light from the explosion eight minutes to travel the 93 million miles from the sun to the earth. However, Newton's Law of Gravity claims that Earth would suffer an immediate departature from its normal ellpitctal orbit. If this were to happen knowlege of the sun's explosion would be instant due to the sudden change in the gravitational force conducting the Earth's motion.

Nuclear fusion occurs in the nucleuses of two elements that have somewhat light masses. The nucleuses of these two elements are brought together at extremely high speeds to ultimately create the new nucleus of a new element. Very few radioactive particles are created through this process, it also mostly takes place in the stars. Where as in nuclear fission, the nucleus of a heavy atom is split into two smaller nuclei. During this process the loss of neutrons releases energy in the form of gamma rays. This process rarely occurs in nature due to the force require to split an

known as the "binding energy". All stars have nuclear fusion occurring until the end of

When this happens several things can happen depending on the size and mass of the star. Take our Sun for example, when it grows old it will enlarge into a Red Giant, then it will shrink into a White Dwarf. This is one of the more “Peaceful” options. (It will engulf Mercury and Mars when it is a Red Giant and make life on Earth very hot.) However if the star has a very large mass, at least 1.4 times the mass of our sun, it will explode in a supernova casting away most of the star's mass. Leaving only the core, the core will begin to collapse, only this time it can’t explode with no fuel left. So it shrinks to a tiny size but it retains its same mass and is extremely dense. Edward Rayne says “[after] the star's collapse it will continue to shrink until the matter is all compressed into an infinitely small, infinitely dense point called a singularity. This is the centre of a black hole.” This is when the black hole forms.

A supernova is a galactic occasion that happens amid the last stellar transformative (the procedure by which a star changes through the span of time. Contingent upon the mass of the star, its lifetime can run from

These celestial bodies begin as a region of cold, high density nebula that condenses into a globule of gas and dust. Over millions of years, the cloud is compacted and the cold nebula gas begins to heat up as the molecules get excited for reacting together. Atoms within the nucleus of this Protostar begin to clash with one another combining hydrogen atoms to form helium atoms. As a result, the energy needed to sustain itself throughout its life, is created by these reactions within the transformation

This article talks about how a star explodes. When a star explodes, it either completely blows up or it leaves a black hole behind. Some stars explode with titanic explosions called Supernovae. Supernovae are put into two categories, Type I and Type II. A well known Type I is called Type Ia. Type Ia is when a white dwarf star blown up. One theory as to why this happens is called stellar cannibalism. This is when a white dwarf star has a star that is near it, it might steal gas from the star. Type II supernovae however, are most likely born in galaxy spiral arms. Type II supernova's brightness usually stays bright for up to two months. Then it goes down over the next few months. I would definitely like to read more about the explosion of stars,

Similar to white dwarfs, neutron stars formed when the original star cannot support themselves against gravitational collapse by generating thermal pressure. They are born from once large stars that grew to be four to eight times the size of our sun before exploding. After the explosion, the only part of the star that remains is its core, but it no longer produces nuclear fusion. The neutron star density causes protons and elections to combine into neutrons, which is how the star got its name. Neutron stars rotate in space when they are formed but as they compress and shrink, the speed of rotation increases. A form of neutron stars are called pulsars. Most neutron stars gradually slow down over time, but the ones that remain spinning emit radiation that cause the star to appear

The star starts off as a nebula. (Along with every other star). From there, the star would become a protostar. Following the smaller sized star would become a Red Dwarf star. When the star is in this stage, it is in its main sequence and will stay in this stage for a very long time. As time passes the star will begin to become a Red Giant. After this stage in the star’s life, the star will begin to cool down, and become a white dwarf. From the white dwarf stage, the star will be coming to an end. The final stage will come to the black dwarf stage where it would be there for a very very long

If the production of nuclear weaponry is not diminished, it will cause the end of everything. With the production of nuclear weapons increasing, it will only be a matter of time until a nuclear war breaks out. When a nuclear weapon is used, it has three killing modes. The first would be the impact, when the bomb first hits. The second would be the shockwave that extends outward a good deal. Thirdly, the radiation effect would kill several more after that.

When such a massive star consumes all its nuclear fuel, it undergoes a 'supernova' explosion and most of the matter is expelled. The extreme heat generated during such explosions can form elements heavier than iron through nuclear fusion.

In larger stars, the core’s temperature increases enough to burn carbon into neon. Burning and contraction are repeated until iron is established in the core. The pressure of neutrons will interrupt the collapse of the core, creating a neutron star. The sudden cease in the contraction of the core allows some of the mass to flow inward. The core becomes heavier and can’t tolerate it’s own gravitational force. This creates a shock wave blowing the outer layer of the star apart in a core-collapse supernova eruption. This explosion results in the distribution of elements throughout the

For my term project, I plan on addressing the observation of SN 1572, better known as “Tycho’s Supernova”, by conducting a solo, explanatory podcast. Observed by Tycho Brahe in 1572, this supernova challenged the way astronomers conceived of the universe. Prior to advanced telescopes and other technology, naked-eye observations were crucial to provide evidence to support the Ptolemaic or Copernican way of thinking, rather than the Aristotelian system (Bennett et al. 68). Aristotle, and others later on, previously believed that the universe was “perfect and unchanging” (71). While Tycho may not have been able to explain everything that he saw, he measure its stellar parallax to observe that this supernova was much further away from the Earth

The Supernova is a new thrill ride that is coming to an exciting park this upcoming year. While designs are still being finalized, roller coaster enthusiasts have already exclaimed how exhilarated they are to ride it. It will reach speed up to 104 miles per hour and will also feature a 45 meter drop at 65 degrees.
