Essays on Supermassive Black Hole

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 ...

- 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 ...

- 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

Our solar system is located in one of the two major spiral arms of the disk-shaped Milky Way Galaxy. It is not located in the center or nucleus of Galaxy because the supermassive black hole Sagittarius A*, because of its tremendous gravitational force, make it possible for clusters to remain intact. In the halo of a galaxy, there are mostly spherical distribution of globular clusters, dark matters, and isolated stars. If between the two spiral arms, it is tantamount to saying that our Galaxy is at its nucleus. At the central bulge, it is made mainly of gas, dust, and ...

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 ...
