Spectroscopy
This tool is used to separate light into its component wavelengths.
What is a spectroscope?
This happens to the wavelength of light from galaxies moving away from us.
What is redshift?
All stars begin their life in this type of cloud made of gas and dust.
What is nebula?
The reason Earth has seasons.
This is the largest planet in our solar system.
What is Jupiter?
This is the type of energy released when an excited electron falls to a lower energy level.
What is light?
Redshift is evidence that the universe is doing this.
What is expanding?
During this stage, a star fuses hydrogen into helium and shines steadily.
What is main sequence?
The side of Earth facing the Moon experiences this type of tide.
What is high tide?
The Moon shines in the night sky because of this.
What is reflection of sunlight?
This is the color of visible light with the longest wavelength.
What is red?
This theory explains how the universe began from a single, incredibly dense point.
What is Big Bang Theory?
A star like our Sun will expand into this stage after it runs out of hydrogen in its core.
What is red giant?
The Sun appears to rise and set each day because of this motion of the Earth.
What is rotation?
This is the name of the galaxy we live in.
What is the Milky Way Galaxy?
The method used to determine which elements are present in stars.
What is spectroscopy?
The astronomer credited with discovering that galaxies are moving away from us, and the farther they are, the faster they move.
Who is Edwin Hubble?
High-mass stars end their lives with this powerful explosion.
What is a supernova?
The solstice when your shadow is longest.
What is winter solstice?
The protective layer in Earth’s atmosphere that blocks most UV rays.
What is ozone layer?
This property of a light wave determines whether we see it as red, blue, or another color.
What is wavelength?
As the early universe expanded, its temperature did this.
What is decrease?
A star’s final stage depends mostly on this property.
What is mass?
We have different constellations in the night sky at different times of year because of this motion.
What is revolution or orbit?
This is the number of stars in our solar system.
What is one?
