Edwin P. Hubble Planetarium, located in the Edward R. Murrow High School, Brooklyn, New York; [58] Edwin Hubble Highway, the stretch of Interstate 44 passing through his birthplace of Marshfield, Missouri; [59] Hubble Middle School, a public school in Wheaton, Illinois, where he lived from 11 years old and up.

This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
H 0 is Hubble's constant and corresponds to the value of H (often termed the Hubble parameter which is a value that is time dependent and which can be expressed in terms of the scale factor) in the Friedmann equations taken at the time of observation denoted by the subscript 0. This value is the same throughout the universe for a given comoving ...
The Hubble Space Telescope is known for its dazzling images of cosmic phenomena, but it didn't exactly start that way. Its first ever image, captured 25 years ago today, is decidedly less exciting ...
It was used by Edwin Hubble to make observations with which he produced two fundamental results which changed the scientific view of the Universe. Using observations he made in 1922–1923, Hubble was able to prove that the Universe extends beyond the Milky Way galaxy, and that several nebulae were millions of light-years away.
1923 – Edwin Hubble measures distances to a few nearby spiral nebulae (galaxies), the Andromeda Galaxy (M31), Triangulum Galaxy (M33), and NGC 6822. The distances place them far outside the Milky Way, and implies that fainter galaxies are much more distant, and the universe is composed of many thousands of galaxies.
Later in the 1920s, Edwin Hubble showed that Andromeda was far outside the Milky Way by measuring Cepheid variable stars, proving that Curtis was correct. [6] It is now known that the Milky Way is only one of as many as an estimated 200 billion (2 × 10 11) [7] to 2 trillion (2 × 10 12) or more galaxies in the observable Universe.
Comet Hubble, formally designated C/1937 P1, is the first and only comet discovered by astronomer Edwin Hubble. The comet was already on its outbound flight when it was first spotted in August 1937 as a magnitude 13.5 object in the constellation Sagittarius. [1] [5] It is the fourth comet discovered in 1937.
