Comparison Between Novas And Supernovas

Introduction The topics that will be explored in the following essay are Novas and Supernovas. In relation to the scope of the course Novas and Supernovas are one of the less obscure concepts for a lot is already known about them. Plus, they are not the hardest concept to understand for basically they are celestial explosions, and if there is anything the masses understand it is explosions. Novas and Supernovas are a part of Strange Science for the full understanding is not yet proven. As only base studies can be done for as the light from them has traveled a vast distance, if one was to send a probe to study them, the explosion would have dissipated by the time it arrived.

A Nova is a cataclysmic nuclear explosion on a white dwarf's surface in a binary star system, which causes a sudden brightening of the star, sometimes million times brighter then normal. (Nave, 2012) The gas exploding can occur many times and differing amounts of reaction. Whereas a Supernova is a violent explosion of a star that produces light as bright as billions of normal stars. It also produces heavy elements, such as iron and nickel during their explosions. (Garner,

(Garner, 2015) Foley first thought that the young stars had settled into their "final resting spots". So he sent out to determine how fast the stars were traveling before the explosion took place. What he discovered was that they moved at about the same speed as stars that have been tossed out of our Milky Way central black hole, at more than 7 million kilometers an hour. So Foley turned his attention to the aging galaxies in the area of the speeding supernovae confirming that many are massive elliptical galaxies that were merging or had recently merged with other galaxies. Foley hypothesizes that a pair of black holes in the merging galaxies provided the gravitational pull to push the white dwarfs into intergalactic space. Eventually, the white dwarfs get close enough together that one starts with process to become a Supernova. The time it takes for one of these ejected stars to explode is relatively short, about 50 million years. Thus, exploding sooner then scientists expected. (Garner, 2015) However, there is still more to discover such as why these young Supernova explosions are unusually weak. Producing mainly calcium during there explosion, and far less of the heavier elements. So, more investigations will have to be done, to discover more about this topic as is true with many
