Edwin Hubble was born on the 29th of November, in 1889.
What is Edwin Hubble's Birthday?
100
Spiral, elliptical, lenticular, and irregular.
What four types of galaxies did Edwin put in his classification system?
100
Hubble's Law is a statement in astrology that states that galaxies are moving away from each other, and that the velocity with which they recede is proportional to their distance. Basically, the greater the distance between two galaxies, the greater their relative speed of seperation is.
What is Hubble's Law, and what does it state?
100
Albert Einstein and Edwin Hubble.
What is this a picture of?
200
Edwin Attended Oxford University in 1913 on a Rhodes scholarship and studied law. Edwin soon dropped law classes and studied astronomy.
What was Edwin Hubble's Education?
200
Edwin Hubble's classification system was sorted by content, distance, shape, and brightness.
What is Hubble's Classification system for various galaxies?
200
It leads to the picture of an expanding universe. If all objects are moving outward at a constant speed, the boundaries defined by the outermost objects must be continuously growing.
What does Hubble's Law lead to the picture of?
200
The Hooker telescope
What is this a picture of?
300
Edwin Hubble began working at Mount Wilson Observatory in California.
Where did Edwin Hubble begin his astronomy career?
300
Hubble's diagram showed that a galaxy's redshift increased linearly with its distance from Earth. The farther away a galaxy is, the faster it moves away from us.
What does the Hubble diagram show?
300
Hubble's law is used to measure distance. The greater the distance away from us a galaxy is, the greater the red shift.
How is Hubble's Law used?
300
Cepheid Variables.
What is this a picture of?
400
This telescope was the worlds largest at the time, and was used by Edwin Hubble.
What is the Hooker telescope?
400
Edwin Hubble proved that there is more to the universe than just the milky way by taking pictures of Cepheid Variables such as the Andromeda nebula, M31, and Triangulum nebula M33. Using these galaxies he then determined that they were 850 thousand to 900 thousand light years away. He then proved that these spiral nebulae were in fact their own galaxy.
How did Edwin Hubble prove that there are more galaxies out in the universe than just the milky way?

The equation to Hubble's Law is V=HoD
What is the equation to Hubble's Law?

What is this a picture of?

Edwin Hubble first discovered Cepheid Variables.
What did Edwin Hubble discover first while using the Hooker telescope?
500
In 1929, Hubble compared his distances to Slipher's measurements of redshift and made a famous plot, which today is called a Hubble diagram.
What is the Hubble diagram?
500
V=HoD where V is the observed velocity of the galaxy away from us, usually in km/sec. H is Hubble's "constant" in km/sec/mpc. D is the distance to the galaxy of mpc.
What does the equation for Hubble's Law mean?
