Essential Skills and Information to Master
The student will investigate and understand scientific concepts related to the origin and evolution of the universe. Key concepts include
a) cosmology including the Big Bang theory; and
b) the origin and evolution of stars, star systems, and galaxies.
- Stars have a finite lifetime and evolve over time. The mass of a star controls its evolution, lifespan, and ultimate fate. Stars form by condensation and gravitational compression of interstellar gas and dust.
- The Hertzsprung-Russell diagram illustrates the relationship between the absolute magnitude and the surface temperature of stars. As stars evolve, their position on the Hertzsprung-Russell diagram moves.
- Galaxies are collections of billions of stars. The basic types of galaxies are spiral, elliptical, and irregular.
- A light-year is the distance light travels in one year and is the most commonly used measurement for distance in astronomy.
- the sun and relate this to the potential existence of life on planets in its orbit.
- explain the potential origin and role of ultra massive black holes in the center of galaxies.
- using the Hertzsprung-Russell diagram, classify stars as to their place on the main sequence or in beginning or end points in their life cycles.
- evaluate the probability of travel to nearby solar systems using current spacecraft speeds.
- analyze the various fusion products of a blue giant star over its lifetime, and relate this to the presence and abundance of elements that make up our solar system and its contents, including living organisms.
