Describe Circumpolar Constellations
A constellation that releases energy by fusion.
a constellation that increases and decreases over time in a regular, approximately 11 year cycle.
a constellation that never sets below the horizon as viewed from a location on Earth.
Describe the Sunspot Cycle
The number of sunspots release energy by fusion.
The number of sunspots that increases and decreases over time in a regular, approximately 11 year cycle.
The number of sunspots never sets below the horizon as viewed from a location on Earth.
Describe how stars release energy.
Stars release energy by fusion. Hydrogen fuses and that creates helium. When a fusion like this occurs, a lot of energy is released into space.
Stars release energy by increasing and decreasing the 11 year cycle.
Stars release energy because they never set below the horizon as viewed from a location on Earth.
Describe how all galaxies are similar.
All galaxies are similar by hydrogen fuses and that creates helium. When a fusion like this occurs, a lot of energy is released into space.
All galaxies are similar by increasing and decreasing the 11 year cycle.
All galaxies are similar because they never set below the horizon as viewed from a location on Earth.
All the galaxies in the universe contains stars, asteroids, planets, and galactic cloud
