A century ago, Edwin Hubble revolutionized our understanding of the universe by proving that the Milky Way is just one of many galaxies in an ever-expanding cosmos. This breakthrough led to the ...

Curtis argued that the spiral nebulas were galaxies in their own right, but said that the Milky Way was only 10,000 light years across. Shapley argued the opposite. Hubble enters the fray Edwin ...

Edwin Hubble was young and ambitious ... His measurements marked the end of the Great Debate about the Milky Way's size and the nature of the nebulae. Hubble wrote about his discovery to Harlow ...

Edwin Powell Hubble is renowned for determining that there are other galaxies in the Universe beyond the Milky Way, and for observing that the universe is expanding at a constant rate. Hubble was a ...

It definitively showed that Andromeda was far outside of our Milky Way. Edwin Hubble went on to measure the distances to many galaxies beyond the Milky Way by finding Cepheid variables within ...

Say hello to one of the Milky Way's neighbors! This NASA/ESA Hubble Space Telescope image features a scene from one of the closest galaxies to the Milky Way, the Small Magellanic Cloud (SMC).

A century ago, Edwin Hubble revealed that the "spiral nebula" was not part of our Milky Way but located 2.5 million light-years away, about 25 times the Milky Way's diameter. Before this discovery ...

which is three times the size of the Milky Way. Using observations from the Hubble Space Telescope, the Giant Metrewave Radio Telescope, the Atacama Large Millimeter Wave Array and multi ...

Were they part of the Milky Way or entire galaxies on their own? Edwin Hubble set out to answer this cosmic riddle. Vesto Slipher's observations of redshifted light revealed that spiral nebulae ...
