Question #1

Three main layers of the interior of the Sun are convection zone, radiation zone and the core.The central part of the Sun with a radius of about 150-175 thousand km (ie, 20-25% of the radius of the Sun), in which are thermonuclear reactions, called a solar core. The density of material in the core is about 150 000 kg / m ³ (150 times higher than the density of water and ~ 6.6 times higher than the density of the densest metal on the Earth - osmium), and the temperature in the center of the core is over 14 million K. A ...

- Describe the three main layers of the Sun's interior.

The three main layers of the sun are referred to as photosphere, chromosphere and the corona. According to the text ‘Discovering the Universe’ by Comins, N.F & Kaufmann III, W.J, 8th edition, each of these layers has different features that makes them different from one another.

The photosphere is the layer that appears to be the major part of the sun where visible light comes from. Photosphere is about 400km thick with a lower density when compared to that of earth standards. This part of the sun also has a blackbody spectrum. In terms of the sun's atmosphere, photosphere ...

- Where in the Galaxy is the solar system located? a. in the nucleus, b. in the halo, c. in a spiral arm, d. between two spiral arms) e. in the central bulge

The solar system is placed in a spiral arm, considered the most hospitable region in the galaxy. The spiral arms are where the active stars form and they orbit around the Milky Way galactic center and the solar system joins this orbital trip. According to the latest discoveries, the Milky Way galaxy has only two spiral arms (Scutum – Centaurus and Perseus) as opposed of four previously considered ...

Assignment 4

4. Describe the three (3) main layers of the Sun's interior. The three (3) main layers of the Sun’s interior are the Core, Radiation Zone, and Convection Core. First, the Sun’s Core or innermost part, is tightly packed and with a temperature of about 1.5x107 K. It extends from the Sun’s center to the photosphere (that is, approximately 0.25 solar radius or 1.75x105 km). It is at the Sun’s Core that thermonuclear reactions occur because of the enormous temperature and pressures. Second, the Sun’s Radiation Zone or the middle interior part, where energy ...
