In 1925, Edwin Hubble discovered that there are other galaxies beyond our Milky Way. He also observed that these galaxies were moving away from us, leading to the discovery of the expansion of the universe.
Edwin Powell Hubble discovered that our galaxy was not the extent of the universe. Hubble was also the one to first realize that the universe is expanding. The Hubble Space Telescope was named in his honor.
Nebulae have been observed for centuries, but the first documented discovery of a nebula is attributed to Charles Messier in the 18th century. Messier cataloged various astronomical objects, including nebulae, which are now known as the Messier objects.
Philo Farnsworth is credited with inventing the first fully functional all-electronic television system in 1927. However, John Logie Baird is also known for demonstrating the world's first working television system in 1925.
In his first attempts to develop a working television system, Baird experimented with the Nipkow disk, and in February 1924 demonstrated to the Radio Times that a semi-mechanical analogue television system was possible by transmitting moving silhouette images, such as his fingers wiggling, in his London laboratory. Baird gave the first public demonstration of moving silhouette images by television at Selfridges department store in London in a three-week series of demonstrations beginning on March 25, 1925.
Emmett Chappelle was born in Phoenix, Arizona on October 25, 1925.
In 1923, Edwin Hubble showed that the "spiral nebulae" that were presumed to be within our galaxy, the Milky Way, were actually other galaxies that lay far beyond our. The following year, he showed that the Milky Way was just one of many galaxies in the universe. Hubble's discovery, announced on January 1, 1925, fundamentally changed the view of the universe.

Edwin McClellan was born in 1925.
Edwin Nixon was born in 1925.
a telescopeIn 1925, Edwin Hubble discover cepheid variable(s) in what we now call the Andromeda Galaxy. From those he could tell that the group of stars was too far away to be part of the Milky Way. It was the first proof that other galaxies exist.
