Most of the more than or so extrasolar planets found so far were actually discovered by telescopes on the ground. Still, Hubble has made some important advances in our research into alien worlds, such as determining the composition of the atmosphere of an exoplanet for the first time and actually imaging the visible light of Fomalhaut b.
Before Hubble, it was highly uncertain as to when the universe was born, which could lead to unbearable paradoxes, such as the laughable possibility that stars astronomers detected were older than our universe.
By greatly narrowing down the rate at which the universe is expanding, Hubble helped refine estimates of the universe's age down to roughly Stars that are billions of light years away naturally took billions of years to get here, and.
The most amazing thing about Hubble besides its scientific findings could be how surprisingly long-lived it has proven. Five missions to service it over the years not only provided vital repairs but also upgrades that gave it new capabilities each time, enabling it to keep on coming up with new discoveries and even more breathtaking images. After the last mission to service it in , Hubble could go on working for at least five years.

When Was Gorilla Glass Invented. Must Read. Speed The Shift - October 2, The observations also showed that the speed was linked directly to the galaxies' distance from Earth. Hubble discovered that the farther away a galaxy is, the greater its speed. This scientific rule is called " Hubble's Law. Who invented Hubble telescope? Who discovered Hubble's law? Who discovered the first galaxy? Charles Messier. How is space infinite? If the universe is infinite , it has always been infinite.
At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded. In the infinite case, you wouldn't have enough curvature for spacetime to form the hypersphere. How old is our universe? Who discovered red shift? What is Hubble's theory? By , Hubble had discovered enough galaxies to compare them to each other. He created a system for classifying galaxies based on their shape that is still used today, in an evolved form.
Based on this observation, Hubble concluded that the universe is expanding uniformly. Edwin Hubble worked at the Mount Wilson Observatory until the summer of , when he left to do war-related work at the Aberdeen Proving Ground, Maryland.
