Hubble's results for Andromeda were not formally published in a peer-reviewed scientific journal until 1929. [29] Hubble's classification scheme. Hubble's findings fundamentally changed the scientific view of the universe. Supporters state that Hubble's discovery of nebulae outside of our galaxy helped pave the way for future astronomers. [30]
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.

The discovery of Hubble's law is attributed to work published by Edwin Hubble in 1929, [2] [3] [4] but the notion of the universe expanding at a calculable rate was first derived from general relativity equations in 1922 by Alexander Friedmann.
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 ...
Edwin Hubble performed many critical calculations from work on the Hooker telescope. In 1923, Hubble discovered the first Cepheid variable in the spiral nebula of Andromeda using the 2.5-meter telescope. This discovery allowed him to calculate the distance to the spiral nebula of Andromeda and show that it was actually a galaxy outside the ...
It hosts a black hole that is 100 million times the mass of the sun.
In 1929, Hubble discovered a correlation between distance and recessional velocity—now known as Hubble's law. [59] [60] Independently deriving Friedmann's equations in 1927, Georges Lemaître, a Belgian physicist and Roman Catholic priest, proposed that the recession of the nebulae was due to the expansion of the universe. [61]
In the 1920s, astronomers Georges Lemaître and Edwin Hubble discovered that the universe has been expanding since its birth 13.8 billion years ago. But research that began in the 1990s has shown ...
