Life cycle of the stars
Billions and Billions of stars
100
It is how astronomers learn about light.
What is starlight
100
This spectrum shows all the colors of the rainbow.
What is continuous spectrum
100
The brightness of a star as seen from the Earth.
What is apparent magnitude
100
During a star's life cycle, hydrogen changes to helium in a process called
What is nuclear fusion
100
This was created to help scientists compare the brightness and temperatures of a star.
What is H-R Diagram (Hertzsprung-Russell Diagram)
200
It is what stars are made of or their composition.
What is gases.
200
These are made when certain wavelenths of light, or colors are given off by hot gases.
What is emission lines
200
An apparent shift in the position of an object when viewed from different locations.
What is parallax
200
This is where stars are born
What is nebula
200
These stars on not in the main sequence very long because they use up their hydrogen quickly.
What is Blue stars
300
It is what astronomers use to break a starts light into a spectrum.
What is spectograph
300
Early astronomers classified the brightest stars as
What is first-magnitude
300
a collection of stars, dust, and gas bound together by gravity.
What is galaxy
300
This is a stars second and longest stage
What is Main Sequence
300
Brighter stars are located in this area of the H-R diagram
What is Upper region of the H-R diagram
400
This spectrum helps astronomers determine what the composition of a star is.
What is absorption spectrum
400
Due to modern technology, the dimmest stars are classified by these numbers.
What is positive numbers
400
A group of stars that are close together relative to surrounding stars.
What is open cluster
400
This is a stars 3rd stage. Its atmosphere grows and cools. What are stars called in this stage?
What is red giants and supergiants.
400
What measurement is located on the X axis
What is A star's temperature
500
This is the brightness a star would have at a distance of 32.6 light-years from Earth.
What is absolute magnitude
500
The surface temperature of a blue star is
What is above 30,000 C
500
the study of the origin, properties, processes, and evolution of the universe.
What is cosmology
500
In this final stage of a star, no hydrogen is left.
