The primary difference between a nova and a supernova is the strength of the explosion. Novas and supernovas are similar in that they both produce a large release of energy through the exchange of gases between two stars. The stars involved include a normal star and a white dwarf, which is a star that is dying.Know More
A nova occurs when the normal star and the white dwarf orbit each other closely enough for the white dwarf to draw hydrogen gas off the star to create a release of energy. The gas is compressed on the surface of the white dwarf through strong gravitational forces and fuses into helium, which causes the explosion. Visually, the white dwarf becomes suddenly brighter and slowly fades away.
The type of supernova that is similar to a nova goes through the same process, but under the right circumstances, the hydrogen gas compresses more densely. When it fuses on the surface of the white dwarf to become helium, it creates a much larger explosion. The explosion can be so violent that the white dwarf may be completely destroyed.
The second type of supernova happens between a white dwarf and a much larger star. The type of star that creates a supernova has a mass that is eight times larger than the sun. The white dwarf draws the hydrogen gas into its core to create helium, but when the hydrogen runs out, the helium fuses into carbon. From there, a number of fusions occur until the core is primarily made of iron. As the pressure builds further, the iron begins to fuse, extracting the heat and the electrons from the core. This causes the core to collapse and the outer layers of the star to explode, creating a supernova.Learn more about Stellar Astronomy
The primary difference between maturation and learning is that maturation takes place with time, while learning occurs when a person acquires knowledge or experience. Another primary distinction is that maturation is a reflexive process that is not influenced by the environment, but learning requires environmental influence, according to Psychology Campus.Full Answer >
The primary difference between Catholics and Episcopalians is that Catholics believe in transubstantiation, the belief in the pope's authority and the need for private communion as well as different rules for priests, birth control and saints. Transubstantiation is the belief that the communion actually becomes the real body and blood of Christ when the priest prays over the communion.Full Answer >
The primary difference between a job and a career is that a job is often viewed from a short-term perspective, whereas a career is perceived as a long-term employment role. People work jobs to make money, but careers center on areas of passion or ongoing professional pursuits.Full Answer >
