I need some help with the following:
Use a reliable source to find an article (preferably from a scientific journal) that examines a recent discovery or other current event in the field of astronomy. Review the selected article and write a synopsis of its content. I also need the appropriate citation.
Recent discovery in the field of astronomy
The article we are going to review for this assignment is about a new and improved 3D simulation that allows scientists to reveal and reevaluate the composition to the sun. The article is from the National Science Foundation and is run by the U.S. government.
Article - "3-D Images Reveal New Composition of the Sun" written by I. Ramirez, M. Asplund, C. Allende Prieto, L. Koesterke, D. L. Lambert written on August 18, 2010. This article can be found at http://www.nsf.gov/discoveries/disc_summ.jsp?org=NSF&cntn_id=117481&preview=false
?This 3Dimensional recreation was conducted by the NSF-supported Texas Advanced Computing Center to re-examine the composition of the sun and reconsider the existing theories about the structure and evolution of stars in general.
?The outcome of this new 3D recreation demonstrates the quantity of carbon and oxygen in the Earth's closest star, the sun, is 30 to 40 percent lower than formerly understood.
?The article explains how scientists use the chemical makeup of the sun as a ...
The solution describes a recent discovery in the field of astronomy. Specifically, the topic of the composition of the sun is chosen and a recent discovery on this topic is discussed. It compares this new discovery to ones in the past and discusses the changes and the future reprecussions based on this discovery.
The total mass And size of the Milky Way Galaxy
What is the total mass and total size of the Milky Way Galaxy? Is it possible to determine these large quantities even if we've never been able to look at ourselves from beyond our galactic borders? What methods do we use in order to get our calculations, and how accurate do we believe that they are?View Full Posting Details
