This is when the northern hemisphere gets the shortest amount of light in a day

Winter Solstice (Dec, 21-23)

100

The process by by which the nuclei of atoms are combined to make larger atoms.  It is also the power of the stars.

Fusion

100

The force of attraction between two objects with mass.

gravity

100

The type of electromagnetic radiation with the highest energy.

Gamma

100

The star in the HR diagram shown that is in the process of converting hydrogen into helium.

The Sun

100

This property is better known as the magnitude of a star

brightness or illuminosity

100

The person who discovered that all objects in the Universe are moving away from each other.

Hubble

200

This is where scientists believe the moon came from

The Earth

200

When the Sun uses up all of it's hydrogen it will enter this stage of its life.

Red Giant

200

This is what would happen to the planets if gravity ceased to exist but they still stayed together.

They would float off into space.

200

The type of electromagnetic radiation that travels the fastest.

They all travel at the same speed

200

This is what happens in the core of a high mass star that will cause it to go supernova

the production of heavy elements causes it to collapse and then explode

200

The shape of the orbits that the planets travel in around the sun

ellipse

200

The piece of technology that is helping us to learn that the universe may be way older than we originally thought.

James Webb Telescope

300

The primary cause of the seasons on Earth.

The tilt of the Earth as it revolves around the Sun

300

This is how the sun rotates that is different from the planets

the equator rotates faster

300

The two forces that keep the planets revolving around the Sun

Gravity and Inertia

300

This how scientists use light know that the Andromeda Galaxy will eventually collide with the Milky Way Galaxy.  

The blue shift

300

Compared to the Sun, the star in the HR diagram is the brightest and coldest.

Betelgeuse

300

The phase of the Moon when you cant see it

New Moon

300

According to the Big Bang Theory, how are galaxies moving in the universe?

Away from each other

400

Phase of the moon shown in the diagram

Gibbous

400

Dark areas on the sun that are cooler and indicate high solar activity.

Sunspots

400
This is what would happen to the planets if inertia suddenly ceased to exist.

They would be pulled into the Sun

400

The change in wavelength or frequency of a wave as something moves towards or away from you is known as this.

The Doppler Effect

400

A planet found in the "Goldilocks Zone" is likely to be revolving around a star in this stage of it's life.

Main Sequence

400

The specific event depicted here.

Lunar Eclipse

400

Phase of the moon shown here.

Crescent

500

The arrangement of the Sun,Moon and Earth during a lunar eclipse.

The Earth is between the Sun and the Moon

500

Sun spots, flares and prominences are all caused by changes in this.

Magnetic field or lines....magnetism

500

Newton's third law of motion states this

For every action there is an equal and opposite reaction

500

The color of visible light with the shortest wavelength.

Violet

500

A medium mass star in the Main Sequence stage of it's life.

C

500

An astronomical unit is used to measure the distance between objects found here.

In our solar system

500

The days when the entire Earth gets 12 hours of light and 12 hours of dark in a day.

the Equinoxes

600

This is the main reason for the tides on Earth.

Gravitational pull of the Moon.

600

The Solar Cycle of activity is this many years.

11 years

600

The scientist who developed laws that explain the motion of the planets.

Kepler
600

This is what happens to the frequency of a wave as the energy decreases.

it decreases

600

The three possible results of the death of a star.

White Dwarf, Black Hole, Neutron Star

600
The reason that we only ever see the same side of the Moon from Earth

The moon is tidally locked. It revolves and rotates at the same speed

600

The machine that is being used to try to recreate the conditions at the time of the Big Bang

Particle Accelerators (Large Hadron Collider)
