Edwin hubble expanding universe graphs and charts

Edwin Hubble's groundbreaking discovery of the expanding universe a century ago, while working at Carnegie Observatories, revolutionized the understanding of the cosmos, revealing the Milky Way as just one among countless galaxies.

This finding led to the realization that the universe is expanding, forming the foundation of modern cosmology, including the concepts of redshift and the Hubble Constant.

The Sun is the most significant star in the universe, and the Andromeda galaxy contains the second-most significant star.

The flickering star is located 2.2 million light-years away and is 1/100,000th as bright as the faintest star visible to the naked eye.

The ostensibly unlucky star, known as V1, opened a treasure trove of time and space mysteries that continue to confound astronomers today.

Hubble discovered the modest star in 1923 using the world's largest telescope at the time, the 100-inch Hooker Telescope, which was funded by the Carnegie Foundation and located at Mount Wilso
