100

This is the part of the Sun where fusion occurs. 

What is the core?

100

The shortest wavelength on the reference table is classified as this.

What is ultraviolet?

100

The origin of the universe and its expansion are a direct result of this event.

What is the Big Bang?

100

Stars spend most of their life in this phase.

What is the main sequence?

100

This is the type of energy on the reference table with the lowest frequency.

What is microwaves?

200

These are the elements that make up the Sun, as tested by spectroscopy.

What are hydrogen and helium?

200

This is the name of the phenomenon that causes a car to make two different pitches as it approaches and then passes you.

What is the Doppler Effect?

200

We observe this effect due to galaxies moving away from us.

What is redshift?

200
Pollux is in this stellar phase.

What is Giants?

200

This will occur when a massive star stops doing fusion and gravity is the only remaining force. 

What is core collapse/supernova?

300

The phase the Sun will be in when the fusion of hydrogen ends.

What is Red Giant?

300

While the light from the Big Bang explosion is no longer visible, its energy is still detectable in the form of these.

What are microwaves?

300

A cloud of gas and dust in space.

What is a nebula?

300

This star has a temperature of 20,000K and a luminosity of 10,000 solar units.

What is Bellatrix?

300

This is the life span of the star Sirius.

What is 109 years?

400

This is the method in which energy is transferred from the Sun to Earth.

What is radiation?

400

A wavelength of 6.0 x 102 would appear as this color.

What is orange?

400

This is the percentage of the universe that was composed of hydrogen immediately after the Big Bang.

What is 75%?

400

This is the duration of time that a massive star will fuse silicon into iron in its core. 

What is 1 day?

400

This is the measure (in nm) of the longest wavelength of visible light emitted by hydrogen. 

What is 655nm?

500

When the Sun runs out of hydrogen and leaves the main sequence, this will happen to the Sun's mass.

What is decrease? (Though it will get bigger, mass and size are not the same!)

500

Energy with a frequency of 1013 Hz would be classified as this.

What is infrared?

500
The estimated number of years ago that the Big Bang occurred.

What is 13.8 billion?

500

This is the last element created in the Sun's core, as it is too heavy for the Sun to fuse again. 

What is oxygen?

500

FINAL JEOPARDY: This person in New Jersey helped discover the Cosmic Microwave Background radiation in space that proved the Big Bang Theory. (There are two possible answers)

Who is Arno Penzias or Robert Wilson?
