H-R Diagram
The two things graphed on an H-R diagram.
What is temp and brightness?
Type of galaxy with an inner bulge surrounded by arms.
What is a spiral galaxy?
A grouping of stars that look like they make a picture in the night sky.
What is a constellation?
The surface of the Sun that we can see.
What is the photosphere?
Loops of gas that come out of the Sun and then loop back to the Sun's surface.
What is a solar prominence?
Regions most stars spend time on.
What is the main sequence?
Type of galaxy that contains older stars in a oval shape.
What is an elliptical galaxy?
A ball of burning gas/plasma that is undergoing nuclear fusion.
What is a star?
This is the outer layer of the Sun's atmosphere. It is very hot!
What is the corona?
If all the stars were lined up on the same line, their brightness would be referred to as this word.
What is absolute magnitude?
The right side of the H-R diagram has this type of star.
What is red or cooler stars?
Type of galaxy that includes the left overs.
What is an irregular galaxy?
The brightness of a star as seen from Earth.
What is apparent magnitude?
The middle of the Sun where nuclear fusion is occurring.
What is the core?
Method to find distances to near by stars. We used our eyes and fingers to show it in class.
What is parallax?
This type of star might just supernova someday.
What is a red super giant?
Our galaxy.
What is the Milky Way?
What is a white dwarf or black dwarf?
Cooler areas on the Sun. They happen in pairs and follow an 11 year cycle.
What are sunspots?
Used to measure distances to stars and galaxies in space.
What is a light year?
These types of stars are very hot and very large.
What is a blue giant?
A collection of stars held together by gravity. Many times there is a black hole in the center.
What is a galaxy?
Large stars will die in this explosive way.
What is a supernova?
Light takes 50 million years to get through this zone of the Sun.
What is the radiative zone?
Theory about how the entire universe was formed.
What is the Big Bang Theory?
