On the other end of the spectrum, the death of a super-massive star is one of the most brilliant displays of pure power in the universe which includes an amazing light show which has no equal. A super-massive star is exactly what it sounds like, a star so big that it dwarfs our own star in every way. When a super-massive sun begins to run out of out of hydrogen it begins to collapse, but due to its immense gravity and size, the collapse produces such an abrupt implosion that the last remnants of nuclear fusion remaining push all the mass of the star back out into space (Britt, 2007). This can be compared to someone jumping onto a trampoline whose elastic has enough elasticity to force one back into the air. This occurrence is known as a supernova explosion, which is the largest explosion in the known universe. A supernova explosion can even be seen from other galaxies, as scientists have done witnessed from observations using the Hubble telescope. The star is so big, however, that it only blows its outer atmosphere away, still leaving a massive amount of matter that is doomed to collapse again, and this time it will be a one-way ticket to oblivion. The super-massive star finally collapses and its own incredible mass crushes it’s internally and now turns it into a neutron star. An average neutron star is about ten miles in diameter, or the size of Manhattan. Although this

The star has been losing fuel and is burning out, so the star will begin to collapse. When collapsing part of the star will shoot into space and scientist believe this is how a supermassive black hole forms. When the hole is forming, dust and gas is collected from the galaxy surrounding the black hole. Light cannot be released because matter is squeezed together in a small space. Stellar black holes are small but dense and can have 20 times more mass than the sun. Mass is the property of a physical body. When a black hole is forming it is possible for mass to be pulled from stars around the whole. This will help the hole grow in power and

A supernova is an explosion that marks the end of the life of a massive star. A supernova has the mass three times the mass of the sun and explodes. Most black holes form after a supernova or explosion of a giant star. (Sipiera P., 1997).

Supernovas are when stars die, they turn into brilliant points of light and explode. Supernovas are considered the largest explosion to take place in space, and in galaxies, they usually appear in other galaxies, but it’s really hard to find one in our own galaxy because there is always dust that blocks our way, so it can be tough to find a supernova. There are 2 ways a supernova can occur. The first way a supernova can happen is when a star gathers up a lot of matter from nearby stars until the star has a nuclear reaction and explodes which causes a supernova. The second way a supernova can occur is when a star is much bigger

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.

Cassiopeia A Supernova – A Supernova is a star that has exploded and increases in brightness because it’s mass is now ejected.

Approximately 1,000 years ago the pattern of mass loss suddenly changed, and the Cat's Eye Nebula started forming inside the dusty shells. It has been expanding ever since, as discernible in comparing Hubble images taken in 1994, 1997, 2000, and 2002. The puzzle is what caused this dramatic change? Many aspects of the process that leads a star to lose its gaseous envelope are still poorly known, and the study of planetary nebulae is one of the few ways to recover information about these last few thousand years in the life of a Sun-like

Matter is being transferred from the companion star onto the neutron star to form an accretion disc around the star. Angular momentum from the companion star is also transferred to the neutron star during this process, thereby increasing the rotation rate of the neutron star. The resulting pulsars are usually millisecond pulsars in this case (credit: ESA space images).}

This star is formed after a large star has had a supernova explosion. These stars are usually very dense and will eventually produce a black hole. Magnetar is a neutron star with an extremely strong magnetic field. Magnetar stars are highly magnetic objects, they are even stronger than Earth. It is also 100 to 1,000 times stronger than radio pulsar. Because we are unsure how this star can be as strong as it is, theorist say it would have to rotate between 100 to 1,000 times per second. Brown Dwarfs is the in between size of a giant planet and a large star. This star is also a very dense star, but not as dense as the white dwarf. When a star is dying it squeezes all its matter into a tiny space, this is called a Black Hole. Their gravity is so strong from all the matter in a tiny space that nothing, not even light can escape. You can’t detect a Black Hole with the naked eye because it's actually invisible, you need a science telescope to identify them. The Cepheid Variable stars light brightens and dims many times. It’s like when the sun is out then goes behind a cloud then comes back out

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

Type I supernova: star accumulates matter from a nearby neighbour until a runaway nuclear reaction ignites.

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,

Supernovas are the explosion of a star when it reaches the end of its life. There are two ways a star can go supernova. The first way or a Type I supernova occurs in the Binary system which is when two stars orbit the same point. The two stars are a white dwarf and a red giant. A white dwarf is a small dense star that is around the size of a planet and a red giant is a star at its last stages of life. If these two stars are close enough, matter will be transferred to the white dwarf from the red giant. When the star’s core reaches its limit of matter, a thermonuclear detonation will occur leaving nothing behind unless there were leftover elements in the white dwarf or there were elements made in the supernova explosion. One of the elements made in the explosion is radioactive nickel.

Neutron stars are a sight to witness on their own and we are fascinated by them in every way imaginable, including everything else in space, however, there is one sight that we have never seen before that includes such a star and, that being a neutron star merger. A merger being the collision of two stars, in this case two neutron stars, that create a black hole as well as an innumerable amount of energy however, scientists have determined that the amount of energy the merger exhibited was some 200 millions times that of our Sun but, in the form of gravitational waves. This collision had only just reached our small Earth a few days but, collided a few billion years ago some 130 million light years away from planet Earth. We managed to pick

Main sequence stars like our own sun enduring in a state of nuclear fusion during which they will produce energy for billions of years by replacing hydrogen to helium. Stars change over billions of years. When their main sequence phase ends they pass through other states of existence according to their size and other characteristics. The larger a star's mass, the shorter its lifespan is. As stars move toward the end of their lives, much of their hydrogen will be converted to helium. Helium sinks to the star's core and raises the star's temperature—causing its outer shell to expand. These large, puffy stars are known as Red Giants. The red giant phase is actually a prelude to a star shedding its outer layers and becoming a small, dense body called a White Dwarf. White dwarfs cool down for billions and billions of years, until they finally go dark and produce no energy at all. Once this happens, scientists have yet to observe, such stars become known as Black Dwarfs. A few stars avoid this evolutionary path and instead go out with a bang, exploding as Supernovae. These violent explosions leave behind a small core that will then turn into something called a Neutron Star or even, if the remainder is large enough, it is then turned into something called a Black Hole.
