Normal, run of the mill supernovas consist of the inner, tough regions of a star crumpling, while the outer extremities get violently spread out into space in an explosion! Spacedaily.com published an article titled, The making of a supernova, which showcases new research on what scientists have concluded on supernovas. Stars become unstable months before the supernova takes place! Through the use of new technologies embedded in telescopes, we are able to see new “transients” in the night sky that before, were invisible. Researchers still have many unanswered questions such as what causes the transition between the pre-stages of the explosion and then the final event.
Making sense of the seventh conceptual objective, “The composition and motion of stars”, This article conducts their findings through the usage of examining light. Astronomers used many forms of light as in x-rays, and ultraviolet to name a few. They examined the star heating up and ionizing while a cloud of stellar matter enveloped the star whole. Light allows astronomers to examine chemical compositions in space allowing them to understand the process behind situations such as what this one entails. In class, we learned the different forms of light such as infared and visible light. Light does not contain material with it, it is a wave. Depending on the type of light will determine its wavelength. The doppler effect taught me how to examine changes in light spectra which tells us the speed of an object. There are two different lines of spectra, blue, which indicates a object is nearing, and red, the object is moving away. This article tells us what makes up a supernova relating to the composition portion of the objective, while the actual explosion is the motion aspect.
Anything that has involvement with an explosion immediately grabs my attention. What interests me about astronomy is the clash of colors, but more importantly, what causes those colors which is the chemical compounds. Supernovas can be linked to a topic we still do not have sufficient evidence on, black holes. Black holes are a tear in time and space which pull in any light and objects with it. Learning more about this objective has told me more about my favorite topic stated before, black holes. Understanding the differences in light and spectra has given me a better understanding of how astronomers conduct their research as well.
