The definition of a supernova is; An explosion of a star that has reached the end of its life. There is a lot more to it than that. Supernovae can be triggered in one of two ways: by the sudden re-ignition of nuclear fusion in a degenerate star, or by the gravitational collapse of the core of a massive star. Once a supergiant can no longer sustain nuclear fusion, it explodes in a massive supernova. As fusion slows inside the star, it collapses towards its core. Gravity forces the gases and metals to compress at an increasing speed, until the pressures build up at the core and produce a tremendous amount of heat. This stream of energy causes a huge explosion that sends most of the gases, and metals back into space to form a nebula. During a supernova, heavier metals such as uranium and lead can be produced.
The earliest recorded supernova, called SN 185, was discovered by Chinese astronomers in 185 AD. Supernova SN 1572 and SN 1604, are the latest to be observed with the naked eye in the Milky Way, had very notable effects on the development of astronomy in Europe, because they were used to argue against the Aristotelian idea that the universe beyond the Moon

In the perspective of how long a star's lifetime is, its death is very brief. In fact, a star's death may only last a few months. Because of this, the typical person will only experience this rarity, on average maybe once in their lifetime. This is a very tiny fraction in comparison to the 100 billion stars that make up a galaxy. Since the development of the telescope, the field of supernova discovery has extended to other galaxies, starting with the 1885 observation of supernova S Andromedae in the Andromeda galaxy. Supernovae SN 1572 and SN 1604, the latest to be observed with the naked eye in the Milky Way galaxy, had notable effects on the development of astronomy in Europe because they were used to argue against the Aristotelian idea that the universe beyond the Moon and planets was
Nebula that was destroyed after it’s sun went supernova. Troubled by his findings, the priest
Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.

“The privilege of a lifetime is being who you are”- and with the Supernova the deaf can be who they are. A person that is deaf is in a terrible disaster and the rescuers don’t know any sign language and they are in a big crisis This will never happen with Supernova, Supernova is an AdaFruit® design and it has a one of a kind “LED Board” that is made from scratch. Most people that are deaf and don’t have anyone to talk to feel like outsiders. AdaFruit® is like an upgrade to the original RedBot®. The Supernova can be mobilized and controlled to be moved around in any situation, for instance, when there is an earthquake and someone gets hit in the head and that person can’t hear Supernova can come in and see what is wrong. Before all of this the idea was to make a RedBot® that wasn’t even a RedBot® is was going to
Carl K. Seyfert was an American astronomer. Seyfert was born on February 11, 1911. He was the son of a pharmacist in Cleveland, Ohio where he also got his high school education (Messier). Although born in Cleveland, Ohio he died in Nashville, Tennessee on June 13,1960 in a automobile accident. Seyfert was 49 years old when he died. There was a galaxy named the ‘Seyfert galaxy’ after Carl K. Seyfert called attention to them in 1944 (Britannica). In this galaxy there were 2 different types that were recognized. In the year 1943 he made a paper all about stars with strong light emissions (Wikipedia).
If the nebula is dense enough, certain regions of it will begin to gravitationally collapse after being disturbed. As it collapses the particles begin to move more rapidly, which on a molecular level is actually heat, and photons are emitted that drive off the remaining dust and gas. Once the cloud has collapsed enough to cause the core temperature to reach ten-million degrees Celsius, nuclear fusion starts in its core and this ball of gas and dust is now a star. It begins its life as a main sequence star and little does it know its entire life has already been predetermined.
The Big Bang, the alpha of existence for the building blocks of stars, happened approximately fourteen billion years ago. The elements produced by the big bang consisted of hydrogen and helium with trace amounts of lithium. Hydrogen and helium are the essential structure which build stars. Within these early stars, heavier elements were slowly formed through a process known as nucleosynthesis. Nucleosythesis is the process of creating new atomic nuclei from pre-existing nucleons. As the stars expel their contents, be it going supernova, solar winds, or solar explosions, these heavier elements along with other “star stuff” are ejected into the interstellar medium where they will later be recycled into another star. This physical process of galactic recycling is how or solar system's mass came to contain 2% of these heavier elements.
Supernovas are extremely powerful explosions of radiation. A supernova can give off as much energy as a Sun can within its whole life. A star will release most of its material when it undergoes this type of explosion. The explosion of a supernova can also help in creating new stars.
...scientific team (Roach 2012). Turnbull’s team evaluated over 245 Supernovae stars, using various mathematical formulas. The conclusion found that the stars were travelling at approximately 245 kilometres per hour in a certain direction, although the some minor details of what was being measured remained different, like the degree of change regarding motion. Additionally, athour details may make this a weak comparison, as Kaslinsky’s dark flow is moving approximately 4 times faster, running in a unique direction and extending further then Turnbull’s team.
Neutron stars are the leftovers of stars with a mass of four to eight times that of our own sun. A neutron star can be formed when the star goes supernova. A star goes super nova when the star runs out of hydrogen to fuse into helium. When all of the hydrogen is used up, the star starts to fuse helium, and it keeps fusing heavier and heavier elements, until it reaches iron. Once the star tries to fuse iron, the star has effectively died, because fusing iron requires more energy to start the reaction than it will release. As the star fuses iron, it is absorbing energy, and gravity starts to compress the star because the star is no longer able to fight gravity because the fusion in the star has stopped. As soon as the star has been compressed enough, it will restart fusion, releasing incredible amounts of energy, causing a supernova. When a star goes supernova, it blows the outer layers of material off into space leaving only the core. If the star was large enough, only the core will remain. Because the core is unable to produce energy through nuclear fusion, gravity starts to press the core in on itself. As the star gets denser and denser, this process speeds up. Once there is no more room, this process stops
The first person to ever observe the Milky Way was Greek philosopher, Democritus, who said the galaxy may consist of distant stars. In 1610, Galileo Galilei used a telescope to study the Milky Way and came to the conclusion that it was composed of billions and billions of faint stars. Then, in 1750, Thomas Wright c...
Nicholaus Copernicus is one of the most well known astronomers of all time. He is even labeled as the founder of modern astronomy for the proposition of his heliocentric theory (“Nicolaus Copernicus”, Scientists: Their Lives and Works). The heliocentric theory was revolutionary for Copernicus’ time. Copernicus lived during the Renaissance. “The era of the Renaissance (roughly 1400-1600) is usually known for the “rebirth” of an appreciation of ancient Greek and Roman art forms, along with other aspects of classical teachings that tended to diminish the virtually exclusive concentration on religious teachings during the preceding centuries of the “Dark Ages.” New thinking in science was also evident in this time…” This time period became known as the scientific revolution (“Copernicus: On The Revolutions Of Heavenly Bodies). In other words, old ideas were revived in the arts and other means and less emphasis was placed o...
Galileo Galilei is a good person who was unjustly put in jail for solid fact and because your church didn’t want to believe him. He studied many subjects, such as astronomy and mathematics. He proved the Copernican theory with solid evidence, and your clergy decides to put him in jail! His discovery would revolutionize the world of science, and you choose to push him away, locked up from society? That’s not good. Galileo should be set free from jail and all charges because a) The Sun, and all of the other planets are also creations of God, therefore, if the Sun was in the center, and all of the planets, including Earth, revolved around it, the Earth wouldn’t be “less special”, or whatever you want to call it. It’s the same now as it would be if the Sun were in the center of the universe. B) Galileo has the freedom to share his ideas with the world. If he, or someone else, decides to translate any of his works into any language, then that’s fine! C) Think about it: did Aristotle have the telescope-thing-a-majigger that Galileo has now? No, he didn’t! Aristotle didn’t have the supplies to back up
One thing us as humans have never been able to fully understand is astronomy. Always having an unexplained mystery, astronomy also has served as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the night sky on a clear, moonless night.
How could we have forgotten the shock of the supernova that awoke us? After drifting from what are now ever escaping reaches of this universe, a force drew us to the place we would call “here.” The dance began as soon as we had arrived. Many dove into the warm center, but we held back. Our pace was slower, but more anxious than theirs because we had waited billions of years to attempt our plan. We held on to each other as we fought the force of its pull. Its spin aligned us on a disk as it grew massive. Many of them gave in to the temptation of its red glow, but we persisted together, because we knew of an ambitious plan to find the truth.
