Red Shift
The forth planet from the sun
What is Mars?
The first planet from the sun
What is Mercury?
The star and planet system we live in
What is the solar system?
It forms from a nebula and is the first stage of a star's life
What is a protostar?
It's the farthest planet from the sun
What is neptune?
When light or other electromagnetic radiation from an object is increased in wavelength this happens
What is Redshift?
Differing wavelengths of light that start with radio waves and continue to gamma rays?
What is the electromagnetic spectrum?
an increase or decrease in pitch of a sound
What is doppler effect?
They are a collection of billions of stars, gas and dust held together by gravity
What are Galaxies?
It is 13.8 billion years old
What is the age of the universe?
The wavelength of light is shorter than on observed on Earth when this occurs
What is blueshift?
The part of visible light with the longest wavelength
What is the colour red?
The idea that space started in a single point and has been expanding outwards
What is the Big Bang Theory?
It's the galaxy we live in
What is the Milky Way?
The opposite of a redshift is this, where light experiences a shortening of wavelength or an increase in energy
What is a blueshift?
It's the remains of a red giant after it has run out of fuel
What is a planetary nebula?
The effect causes the change in colour noticeable in receeding galaxies
What is redshift?
The value for it is around 2.2 x10^-18 /s
What Hubble's Constant?
The radiation found everywhere in the universe
What is Cosmic Background Radiation (CMB)?
Take the speed, v, at which a galaxy is receding. Divide it by the distance it is from the observer.
What is the Hubble constant?
Infrared radiation, Visible light, and ultraviolet light
Which parts of the EM spectrum does the sun emit most of?
This changes the wavelength of sound from an object relative to a receiver
What is the doppler effect?
It's a collection of gas a dust where stars may (or may not) form
What is a nebula?
This piece of NASA equipment was named after Hubble
What is the Hubble Space Telescope?
