What are the bright lines made when light is given off by hot gases?
What are emission lines
100
Large groupings of stars in space (many sizes & shapes)
What are galaxies
100
A graph showing relationship between a star's surface temperature & absolute magnitude
What is an H-R Diagram
100
Color flame that burns the HOTTEST
What is Blue
100
Which color stars are most like our sun
What is yellow
200
Continuous spectrum with dark lines when light passes through a cooler gas
What is absorption spectrum
200
This type of galaxy has a bulge at the center with spiral arms. An example of this is the Milky Way.
What is a spiral galaxy
200
Band that runs in the middle. Also majority of stars are these kind
What is Main Sequence
200
Color flame that burns the coolest
What is Red
200
If two stars are different colors, we can infer that they have different
What is temperatures
300
Distance light travels in one year?
What are light years
300
This galaxy has massive blobs of stars, very bright centers with very little gas or dust, contains only old stars, & shaped like spheres or elongated. Is made up of 1/3 of all galaxies.
What is a elliptical galaxy
300
A smaller star that has run out of hydrogen & grown large & cool
What is a red giant
300
Rainbow of colors seen through a prism
What is a spectrum
300
Low-mass stars that stay on the main sequence for a long time
What is red dwarfs
400
Apparent shift in position of a planet, star, etc.
What is parallax
400
This content is made up of giant clouds of gas & dust.
What are nebulas
400
Likely the youngest of stars
What is a Blue star
400
When light from a hot solid passes through a cooler gas
What is absorption spectrum
400
Groups of older stars that appear as a ball of stars near spiral and giant elliptical galaxies
What are globular clusters
500
Stars really move, but hard to see because they are so far away
What is actual motion
500
These are distant objects that are very powerful energy sources?
What are quasars
500
Death of a large star by explosion
What is a supernova
500
Spectrum given off by a glowing wire inside a light bulb
What is continuous spectrum
500
Leftovers from a supernova that collapse. Also has gravity that is so strong that light cannot escape it
