Universe 1
For stars, this color indicates a relatively high temperature star.
What is blue-white?
This eventually happens when a star runs completely out of fuel.
What is a supernova?
This happens when a star completely runs out of fuel for fusion reactions.
What is a supernova?
Main sequence stars size and stability is balanced by these two forces.
What are gravity and nuclear fusion?
These two elements comprise main sequence stars.
What are hydrogen and helium?
Evidence for an expanding universe is this.
Most light coming to Earth is red shifted?
These are typically found in the center of galaxies.
What are super massive black holes?
Small or medium size stars tend to end up as these following a supernova.
What is a neutron star?
These are the three types of galaxies?
What are spiral, elliptical, and irregular?
Massive stars end up as these following a supernova.
What is a black hole?
This type of reaction is what occurs in a star.
What is nuclear fusion?
These are 3 basic fates of stars.
What are neutron stars, nebulas, or black holes?
The Milky Way galaxy is this type of galaxy?
What is a spiral galaxy?
Clouds of gas and dust that are centers of star formation are known as this.
What are nebulas?
Distance to other stars are calculated by these two methods.
What are by parallax or brightness?
The idea that the universe started as a single point is known as this.
What is the Big Bang Theory?
It has been found the universe is doing this.
What is expanding at an increasing rate?
All star systems, galaxies, gas, dust, space, and time make up this.
What is the universe?
These are the biggest groups of stars and can contain millions to billions of stars.
What are galaxies?
These massive devices simulate the the reactions occurring in the center of a sun’s core.
What is a particle accelerator?
Calculated mass that is affecting the behavior of observed celestial objects and light is known as this.
What is dark matter?
For stars, this color indicates a relatively low temperature star.
What is red?
Stars are made of this state of matter.
What is plasma?
Stars fusing hydrogen into helium are know to be this type of star.
What are main sequence stars?
This is why black holes are called black holes.
What is the core is so dense, light cannot escape their gravity?
