A large collection of gas, dust, and billions of stars held together by gravity.

Our galaxy, appearing as a milky band of light in the sky.

Our solar system is located on the outskirts of the Milky Way galaxy.

Approximately 100 billion stars.

Maintains the orbits of planets in our solar system.

Quasars are not components of the solar system.

The gravitational pull of the Sun.

A hot ball of glowing gases.

Remnants from the formation of the solar system.

Asteroids and comets have remained largely unchanged compared to planets and moons over time.

Frozen gases, rock, and dust.

A meteoroid that survives its trip through the Earth's atmosphere and hits the ground.

Apparent shift in frequency of a wave caused by relative motion between the source and observer.

Distance between successive crests of a wave.

Highness or lowness of sound.

Light shifted toward lower frequencies (red end of spectrum).

Visible light shifted toward higher frequencies (blue end of spectrum).

Expansion of space.

Light shifted due to massive amounts of matter in a galaxy.

Frequency is vibration rate; wavelength is distance between wave crests.

Studying wavelengths of light using a spectrometer.

An apparent shift in frequency of a wave caused by relative motion between the source of the wave and the observer.

When light is shifted toward lower frequencies (red end of the spectrum.)

Three types of Redshift are from universe expansion, galaxy movement and gravitational redshift.
