In the article, “Violent Collision Triggers Cosmic Fireworks Display,” the author discusses how there was a collision between two stars that triggered a “spectacular stellar explosion like a fireworks show on the Fourth of July,” according to the author. Than they talks about where and when this took place. The author states this explosion took place “500” years ago and in a region known as the “OMC-1” The author considers the OMC-1 an “active stellar nursery” and in this OMC-1 the author states exactly, “”What we see in this once-calm stellar nursery is a cosmic version of a Fourth of July fireworks display, with giant streamers rocketing off in all directions,” John Bally, lead author of the study from the University of Colorado Boulder, said in the statement. ” Than the author explains how if the stars in the galaxy begin to slow down, they tend to fall towards the center of gravity and then collide into other stars which than creates the firework explosion as explained above. Lastly, the author discusses how the new study provided us with new information discussing the force of the blast as well as “”distribution and high-velocity motion of the carbon monoxide (CO) gas inside the streamers,” scientists said.” in the article.
Objective 13 was to be able to effectively describe how stars form and produce energy in their cores by nuclear fusion. This article relates to the stars formation because it discusses young protostars in a molecular cloud. Stars are born in cold, relatively dense molecular clouds. Molecular clouds are never uniform. Some regions inside the cloud are denser than others. Slightly denser regions collapse faster than their surroundings and become more pronounced. The collapsing cloud fragments into dense, star-forming cores. As a cloud fragment collapses under gravity, it becomes a rapidly rotating protostar surrounded by a spinning disk of gas in which planets may form. The lecture tutorial, “Star Formation and Lifetimes,” explains that the inward collapse of material causes the center of the protostar to become very hot and dense. Once the central temperature and density reach critical levels, nuclear fusion begins. During fusion, hydrogen atoms are combined to form helium atoms. When this happens, photons of light are emitted. Once the outward pressure created by the energy given off during nuclear fusion balances the inward gravitational collapse of material, a state of hydrostatic equilibrium is reached, and the star no longer collapse. When this happens, the protostar becomes a main sequence star.
I really found this article amusing because I learned a lot of new information from reading this article. For example, I thought it was very neat how stars can collide into one another and make a huge firework explosion. I guess I kind of believed before everything went so smoothly and perfect in space . So after, hearing this information how collisions happen it made sense to me because just like earth nothing is perfect, and from this article I realizes space is the same.
